Introduction
Introduction

Khirbet es-Suyyagh, located on the northeastern fringe of the Judaean Shephelah (foothills), was occupied from late Hellenistic/Early Roman period to the Abbasid period

History of Research

Khirbet es-Suyyagh was first mentioned by the surveyors of the British Palestine Exploration Fund (PEF), who visited the place (which they called Khǔrbet es-Sîâgh) in 1872. They described it as “foundations and cisterns. Apparently an ancient site” (Conder and Kitchener 1883:125). During the late 20th century the site was surveyed at least three more times by scholars from the IAA. The surveyors of the map of Nes Harim described the site as follows: “Remains of Structures: remains of an oil press and a wine press, rock-hewn steps and cuttings in rock outcrops, on slope (the site was destroyed by development works). Pottery: Roman, Byzantine and Early Islamic” (Weiss, Zissu and Solimany 2004:30*). The site was included also within the survey of Ramat Beth Shemesh and was described in detail. Within its area the surveyor identified foundations of buildings, architectural elements,remains of an oil press, a wine press, a cistern and rock cuttings. He also estimated the total area of the site at 1 hectare – a much larger area than was apparent from the present excavation.This high estimate may have resulted from the fact that the slopes of the spur were also included within the site’s area. According to the surveyor,the pottery found at the site was from the EarlyBronze Age II-III (a few sherds on the eastern slope), Iron Age II (a few sherds throughout the area), Roman and Byzantine (a large quantity)and Early Islamic (a few sherds). 150 m south of the site four rock-cut basins and two cup-marks, an opening of a silt-filled cave and an agricultural enclosure wall, were identified. Associated with these remains were a few sherds from the Iron Age II and many sherds from the Byzantine and Ottoman periods (Dagan, forthcoming).2 In 1998, the site and its immediate vicinity were surveyed, and a few more spots with remains of agricultural installations and Byzantine-period pottery were identified (Greenhut, Weiss and Solimany 2000). Following this survey, a small-scale salvage excavation was conducted to the northwest and south of the site (Greenhut 2001).

In 2004, prior to the present excavation, a limited salvage excavation was conducted at the site by E. Kogan-Zehavi, on behalf of the IAA. The excavation included nine squares and several trenches which were dug in different places throughout the area. These probes yielded parts of a Late Byzantine and Early Islamic complex, to which three architectural phases were attributed. Based on these finds, the excavator was the first to suggest that the complex was a monastery (Kogan-Zehavi 2008).

The excavations conducted at Khirbet es-Suyyagh by the author in 2004 and 2005 included an area of more than 0.2 hectares, within which a built complex was almost fully unearthed. The lion’s share of the remains and finds belong to the Late Byzantine and Umayyad periods, reinforcing Kogan-Zehavi’s suggestion that the complex was a monastery.3 This monastery was part of a small group of Byzantine rural monasteries known so far in the Judaean Shephelah, and one of the few that has been excavated. The present excavations, therefore, provide important additional knowledge not only about the history of the Judaean Shephelah during the discussed periods (and others), but also about the general phenomenon of rural monasticism in Palestine and different aspects related to it.

Chronology
Phasing

Phase Period Comments
I THE LATE HELLENISTIC/EARLY ROMAN AND LATE ROMAN/EARLY BYZANTINE PERIODS Some find spots and a few architectural remains that pre-dated the foundation of the Christian monastery were unearthed. The only feature which can be securely dated to the late Hellenistic/Early Roman period (i.e., the late Second Temple period) is a cistern unearthed in Squares D-E/9-10 (Figs. 2.1:24, 2.2, 2.3).

... ‎ The relatively small number of finds belonging to this period and their concentration in the northern part of the site, points to small-scale activity taking place here during that time. Based on the finding of the cistern and the relatively varied pottery assemblage, it seems that there was here a small farmhouse, perhaps inhabited by no more than one family (Chapter 10).

The next stage of occupation at the site can be dated, on the basis of pottery and coins, to the Late Roman and/or Early Byzantine period (the 4th- [early?] 5th centuries CE). As in the Early Roman period, the architectural remains and most of the pottery that belong to this span of time were also concentrated in the north of the site.
II THE LATE BYZANTINE/EARLY UMAYYAD PERIOD The architectural picture of Khirbet es-Suyyagh, as known from the excavations, originated mainly in the Late Byzantine to Abbasid periods. Two major stages of site formation can be identified within Phase II, which represent the time of the monastery’s heyday during the Late Byzantine and early Umayyad periods (the 6th century CE to late 7th/early 8th century CE). Attributed to the first stage (Phase IIA) is the foundation of the monastery and its main time of existence, which ended in the destruction of parts of the monastery sometime around the mid-7th century CE. The second and shorter stage (Phase IIB) represents the time between its reconstruction and its abandonment by the monastic community. It must be noted that there were sometimes difficulties in determining whether a certain remnant or feature belonged to Phase IIA or Phase IIB, or to Phase IIB or Phase III.

... Phase IIB seems to have ended around the late 7th/early 8th century.
III THE LATE UMAYYAD/'ABBASID PERIODS Due to later use in the post-monastery phase and the remodelling which took place at that time, it was not always easy to distinguish between the remains and finds of Phases IIB and III. However, the nature and location of some of the features which postdate Phase II clearly indicate that at the time of their construction the site no longer functioned as a monastery, and therefore they can be securely attributed to Phase III.

Phase IIB seems to have ended around the late 7th/early 8th century. Later, maybe after a short gap in occupation, the site was resettled. This time the inhabitants were no longer Christian monks, but simple peasants, who’s religious identity is yet unclear

Most of the walls attributed to Phase III were built rather poorly compared to the walls of Phase IIA and even to some of those of Phase IIB. These walls can be distinguished from the walls of the previous phases by their rough, sometimes slapdash construction, which used stones of various sizes, including older ashlars and other architectural elements in secondary use. Architectural remains and small finds which can be attributed to this phase were found throughout the site. The most prominent characteristics of the building activity of Phase III are the re-division of rooms and spaces and the blocking of old doorways and passages.

End of Phase IIA Earthquake(s) - 7th century CE

Taxel et al (2009) surmised that Phase IIA ended with an earthquake and established a terminus post quem of 629/630 CE for repairs to damaged parts of the monastery at the start of Phase IIB. This was based on a 629/630 CE coin found below the mosaic floor in the northern aisle of the church (Locus 387) attributed to Phase IIB. Another coin of Constans II (641-648 CE) was found in the fill that covered the corridor north of the main gate (Locus 281) however it was noted that this fill could also be related to the construction of the blocking wall of the corridor in Phase III. Pottery found below the fieldstone paving which abutted on the new (southern) storeroom in the external courtyard and to the repaired doorway of the subsidiary gate (Loci 181 and 183) was dated to the mid-late 7th century. Lack of fire evidence and evidence of archaeoseismic damage led Taxel et al (2009) to conclude that observed damage and repairs of damage was probably due to an earthquake(s) although destruction due to Persian and, later on, Muslim military activity could not be entirely ruled out.

Khirbet-es-Suyyagh in Context

The monastery in its original form (Phase IIA) continued to exist as a strong economically independent unit until the end of the Byzantine period or sometime after, when the complex was partially destroyed probably by one of the earthquakes which hit Palestine in the 7th century. The damaged parts of the monastery were then renovated in a relatively rough manner. The terminus post quem of these repairs is given most precisely by the coin dated to 629/630 CE which was found below the mosaic floor in the northern aisle of the church (Locus 387) attributed to Phase IIB. There are also other finds which can date the beginning of Phase IIB to the mid-7th century. The first is a coin of Constans II (641-648 CE), which was found in the fill that covered the corridor north of the main gate (Locus 281). This coin, however, can also be related to the construction of the blocking wall of the corridor in Phase III. The other finds are represented by the pottery found below the fieldstone paving which abutted on the new (southern) storeroom in the external courtyard and to the repaired doorway of the subsidiary gate (Loci 181 and 183).

Theoretically, the Sassanid-Persian conquest of 614 CE could have been responsible for the destruction at the end of Phase IIB. The literary sources which deal with the conquest mention the destruction of churches and monasteries and even massacre of Christian communities in western Galilee but mainly in Jerusalem and nearby (Schick 1995:21, 31, 33-39). However, these events occurred only in the initial stage of the conquest, and were not reported from the period of the Persian occupation which lasted until 628 CE. Some of the damaged buildings – mainly in Jerusalem – were repaired soon after the conquest, and the reoccupation of some of the abandoned monasteries also occurred at about that time (Schick 1995:41-43). Some renovations were probably carried out after the renewal of the Byzantine rule in Jerusalem in 630 CE, but these were few and undocumented in the archaeological record (Schick 1995:65-67). Therefore, it does not seem very plausible that the monastery of Khirbet es-Suyyagh was damaged in the conquest of 614 and remained partially destroyed (and abandoned?) until at least 629/630 CE. Furthermore, the nature of the damage and renovations does not indicate violent destruction by human agency. The almost total absence of traces of fire weaken the possibility that the monastery of Khirbet es-Suyyagh was damaged during the Persian conquest.

Nor does it seem that this destruction should be attributed to the Muslim conquest of Palestine in the 630s. There is little evidence for deliberate violent destruction of Christian sites at the beginning of the Early Islamic period (Schick 1995:128). Nonetheless, the excavator of nearby Khirbet Fattir suggested that the destruction of that site in the 7th century was caused either by the Persian invasion or by the Muslim army who defeated the Byzantines at the battle of Ijnādayn in 634 CE and “…plundered and destroyed the Christian villages with their sanctuaries in the neighborhood…” (Strus 2003:430). Similarly, the Persian or Muslim conquest was identified as the cause of the destruction of the farmhouse of Khirbet el-Jiljil, although the excavators did not rule out the possibility that an earthquake was responsible (Strus and Gibson 2005:72).

One of two earthquakes documented by contemporary and later sources could have hit Khirbet es-Suyyagh. According to Russell, the first earthquake occurred in September 633 (1985:46), although Guidoboni predates this event to 631/2 CE (1994:504). The intensity of this earthquake and the exact area affected by it are unknown. The only place mentioned in the sources as damaged by the earthquake is the church of the Holy Sepulchre in Jerusalem [JW: This was a mistake made by Michael the Syrian attributing seismic destruction to the Church of the Holy Sepulcher. The Church of the Holy Sepulcher was destroyed in 614 during the Sasanian conquest of Jerusalem and was fully rebuilt when Omar visited it in 637 CE. See Sword in the Sky Quake -> Textual Evidence -> Michael the Syrian. In fact, part of the mystery of the Sword in the Sky Quake is that no locations are mentioned by the various authors]. According to Russell it [the Sword in the Sky Quake] was less destructive than other recorded earthquakes and affected a relatively limited area (1985:46) [JW: Russell (1985) lacked sufficient evidence to make such a statement]. Schick suggested that this earthquake could have been responsible for the destruction of ecclesiastical complexes in Palestine and Transjordan, mainly along the Jordan valley (1995:24, 66, 125).

A stronger earthquake occurred in June 659 followed by another in 660 CE (Russell 1985:47) which caused destruction throughout Palestine and Transjordan [JW: We do not know if the Jordan Valley Quake(s) was/were stronger than the Sword in the Sky Quake and, more importantly, which quake(s) would have generated higher intensities at Khirbet es-Suyyagh]. The sources mention several specific settlements and ecclesiastical complexes in Jerusalem and the Jordan valley that were damaged or destroyed by this earthquake, such as the monastery of Euthymius [JW: true]. Indeed, excavation of this monastery revealed evidence of its almost complete renovation after the earthquake of 659 CE (Hirschfeld 1993:357) [JW: also true]. This earthquake was identified archaeologically also at other sites in the Jordan valley, including Pella (Schick 1995:66, 125- 126; Walmsley 1992:254) [JW: Walmsley dated seismic destruction at Pella to the 7th century], and at Caesarea (Raban, Kenneth and Bukley 1993:59-61) [JW: Langgut et al (2015) report that destruction of a building in Caesarea Maritima was tentatively attributed to the 659 CE earthquake by Raban et al (1993:59-61)].

It is hard to determine which of the two above-mentioned earthquakes hit Khirbet es-Suyyagh. Apparently, the finding of the 629/630 coin below the church mosaic make the option of the 631/2 or 633 earthquake more plausible. However, archaeological evidence from other sites in Palestine and the neighbouring regions clearly shows that coins of Heraclius remained in circulation well into the Umayyad period (Magness 2003b:149, 170; Walmsley 2000:332-333). On the other hand, support for the 659/660 earthquake can be given by the pottery found in Loci 181 and 183, which can be dated to the mid-late 7th century. Thus, the possibility that the site was hit by the 659/660 earthquake rather than that of 631/2 or 633 seems somewhat more reliable. Still, the possibility that another undocumented earthquake hit the site sometime around the mid-7th century, as maybe happened at Beth Shean, cannot be ruled out (Tsafrir and Foerster 1997:143-144).

Earthquake-related Damage Discussion

Damage to man-made features and natural bedrock is recognized at some points at the site of Khirbet es-Suyyagh. There are three types of plausible causes for this damage: deliberate man-made destruction, slow protracted wear of masonry and erosion of underlying rock, and catastrophic earthquakes. Distinguishing the three types is important for understanding the human and natural history of the region in general and of Khirbet es-Suyyagh in particular. Damaged architectural remains can be recognised throughout the site. Signs of destruction and nearly immediate rebuilding combined with absence of signs of man-made violent actives are typical earthquake-related features.

The area of the large courtyard (Fig. 2.1:8-10) had been completely rebuilt after a destructive event. An earlier construction phase, which is observed south of the centre of the courtyard (Fig. 2.1:9), is covered by a later floor. Fallen masonry and subsequent repairs were observed in the southern part of the apse of the church, with its inner face remaining asymmetric. Since the damage is observed close to the foundations of the church it seems that the damage had a pervasive affect on the entire structure. A section of about 10 m in the southern end of W33 seems also to have been rebuilt. Similarly, in W100 there is a warped contact in room 19, where two different styles of masonry meet but are misaligned.

Another type of damage appears in two broken door thresholds, that of the main gate and that of the small courtyard in the south of the monastery. The large, monolithic and nicely carved stones are placed in-situ but broken by a width wise crack into two pieces. Assuming the thresholds were carved from intact rocks without significant fractures, we can envision strong vertical acceleration, perhaps of the order of 1g, which caused the fracturing. Such strong shaking is known based on modern earthquakes to occur either near the epicentre of strong earthquakes (of the order of magnitude 7 and above) or in places with strong local amplification of seismic waves.

Each of the damaged elements alone would not suffice to indicate an earthquake as the damaging agent. However, the occurrence of many such elements, the extensive repair and reconstruction of features without any sign of human violence and in short time, together with the frequent occurrence of earthquakes in the region supports the association of the damage to earthquake/s.

Ideally, the proposed evidence for earthquake related damage would be corroborated by historical accounts and/or by additional independent archaeological observations in contemporary sites and/or geological evidence. Geological evidence for strong earthquake shaking in the vicinity of the site is found in the form of fallen cave deposits (speleothems), in particular stalactites and stalagmites. The damage events to speleothems were dated using the Uranium-series method (Kagan et al. 2005). Several breakage events of speleothems were identified in the Soreq and Har Tuv caves, the age of the youngest of which is estimated by five millennia. A doctorate in progress by E. Kagan (the Hebrew University of Jerusalem) indicates that the analytical methods that were used in the previous stage (i.e., alpha counting) are not sensitive enough and by using MC-ICP-MS system younger historical events are emerging (personal communication).

Hence, the regional seismic activity is capable of triggering severe damage in the vicinity of Beth Shemesh. The time of the damaging episode in Khirbet es-Suyyagh is determined by the ceramic and numismatic finds to around the middle of the 7th century. This is supported by historical accounts on 7th century earthquakes, which report considerable damage in Judaea by earthquakes that are dated to 631/2 CE and 659 CE (Amiran, Arieh and Turcotte 1994; Guidoboni 1994:355-358; and see Chapter 10). These reports need to be examined in detail and cross-checked in further studies.

The most likely source of earthquakes in this region is the Dead Sea fault, an active boundary between the Sinai and the Arabia tectonic plates. The plates’ relative movements of average 4-5 mm/yr trigger occasional strong earthquakes. The earthquakes are recognized in numerous damaged archaeological sites throughout the Middle East as well as in deformed rock units (e.g., Amit et al. 2002; Kagan et al. 2005; Marco and Agnon 2005; Marco et al. 2005) The nearest segment of this fault is in the Jordan valley, some 50 km east of the site, which ruptured in the earthquakes of 31 BCE, 363 CE, 749 CE, and 1033 CE (Marco et al. 2003).

In conclusion, it is highly likely that the observed damage and subsequent repairs in Khirbet es-Suyyagh were caused by one or more earthquakes.

The Gatehouse

The destruction caused to the monastery by the earthquake that marked the end of Phase IIA is very apparent in the area of the main gate. The massive threshold was broken into two large pieces (see Chapter 9). The remains which point to the architectural changes that took place here during Phase IIB are:
  1. The western part of the monastery’s southern wall, which included the main gate, is not built exactly on the same line as the rest of the wall. In addition, the level of the main gate’s threshold itself is 0.5-0.6 m higher than that of the path which leads to it from the south. This height difference did not, of course, allow comfortable passage from the path into the monastery

  2. The western edge of the gate ended without being connected to any of the other nearby walls, e.g., those of the church complex (Fig. 2.15). Actually, only a thin wall (W218; whose first course is built of three small coarsely-carved stones) abutted on it from the south and connected it to the church’s apse, while creating a small trapezoidal room (Room 33; 2.3-3.3×2.2 m)

  3. The path and the entrance corridor to its north was found covered with a fill rich in pottery sherds and other finds.
At the time of the reconstruction, the gate was not only rebuilt along a somewhat different line than the rest of the southern wall, but also its threshold was raised. The original, broken, threshold remained in use in the new gateway. It is possible that the continuation of this wall toward the church complex was also destroyed, and the present thin wall was built instead. The problem of height difference in the gate area was solved by laying an earth fill (Loci 341, 358, 362, 370, 379) which covered the outer path and created a ramp that led to the new threshold level. The same fill continues north of the gate – all along the entrance corridor, up to the height of the second stair from the bottom (Loci 240, 281, 325, 330, 342, 368, 374). It was found that W207 was founded on the same fill, 0.45 m higher than the bedrock surface. This wall was indeed built from ashlars, but rather crudely without any real foundation course. It seems, therefore, that the original wall was also destroyed or damaged by the earthquake, and rebuilt later at a higher level than before.

Wall W33

Another alteration identified in this area is the rebuilding of the last 10 m of the southern end of W33. This section of the wall, excluding maybe the foundation course, was completely destroyed and rebuilt in a different manner than was usually common at the site. The rebuilt part, which was 0.4 m wider than the original wall, was made of small and medium-sized fieldstones bound with mortar. Theoretically, it seems that the southern end of W33 was destroyed during the earthquake that hit other parts of the monastery at the end of Phase IIA. However, we cannot say if the renovation of the damaged section occurred during Phase IIB or only in Phase III.

Subsidiary Gate and Central Courtyard

The original arrangement of the courtyard was changed, probably due to the earthquake that struck the monastery at the end of Phase IIA. The walls of the entrance room or corridor were demolished down to their foundation course. The floor of this room/corridor, which was lower than those of the courtyards themselves, was raised to create a uniform-level platform in which were embedded the remains of the entrance room.

The storerooms in the Western Unit

The construction of this storeroom can be attributed to Phase IIA, and it probably collapsed in the earthquake that ended this phase.

Damage Descriptions for entire site (some repetitive)

Damaged architectural remains can be recognised throughout the site. Signs of destruction and nearly immediate rebuilding combined with absence of signs of man-made violent actives are typical earthquake-related features.

The area of the large courtyard (Fig. 2.1:8-10) had been completely rebuilt after a destructive event. An earlier construction phase, which is observed south of the centre of the courtyard (Fig. 2.1:9), is covered by a later floor. Fallen masonry and subsequent repairs were observed in the southern part of the apse of the church, with its inner face remaining asymmetric. Since the damage is observed close to the foundations of the church it seems that the damage had a pervasive affect on the entire structure. A section of about 10 m in the southern end of W33 seems also to have been rebuilt. Similarly, in W100 there is a warped contact in room 19, where two different styles of masonry meet but are misaligned.

Another type of damage appears in two broken door thresholds, that of the main gate and that of the small courtyard in the south of the monastery. The large, monolithic and nicely carved stones are placed in-situ but broken by a width wise crack into two pieces. Assuming the thresholds were carved from intact rocks without significant fractures, we can envision strong vertical acceleration, perhaps of the order of 1 g, which caused the fracturing. Such strong shaking is known based on modern earthquakes to occur either near the epicentre of strong earthquakes (of the order of magnitude 7 and above) or in places with strong local amplification of seismic waves.

Each of the damaged elements alone would not suffice to indicate an earthquake as the damaging agent. However, the occurrence of many such elements, the extensive repair and reconstruction of features without any sign of human violence and in short time, together with the frequent occurrence of earthquakes in the region supports the association of the damage to earthquake/s.

    At the time of the reconstruction, the gate was not only rebuilt along a somewhat different line than the rest of the southern wall, but also its threshold was raised. The original, broken, threshold remained in use in the new gateway. It is possible that the continuation of this wall toward the church complex was also destroyed, and the present thin wall was built instead. The problem of height difference in the gate area was solved by laying an earth fill (Loci 341, 358, 362, 370, 379) which covered the outer path and created a ramp that led to the new threshold level. The same fill continues north of the gate – all along the entrance corridor, up to the height of the second stair from the bottom (Loci 240, 281, 325, 330, 342, 368, 374). It was found that W207 was founded on the same fill, 0.45 m higher than the bedrock surface. This wall was indeed built from ashlars, but rather crudely without any real foundation course. It seems, therefore, that the original wall was also destroyed or damaged by the earthquake, and rebuilt later at a higher level than before

Southern end of Wall W33


  • Another alteration identified in this area is the rebuilding of the last 10 m of the southern end of W33. This section of the wall, excluding maybe the foundation course, was completely destroyed and rebuilt in a different manner than was usually common at the site. The rebuilt part, which was 0.4 m wider than the original wall, was made of small and medium-sized fieldstones bound with mortar. Theoretically, it seems that the southern end of W33 was destroyed during the earthquake that hit other parts of the monastery at the end of Phase IIA. However, we cannot say if the renovation of the damaged section occurred during Phase IIB or only in Phase III. - Taxel et al (2009:186-187)

Subsidiary Gate and The Large Central Courtyard

  • The area of the large courtyard (Fig. 2.1: Rooms 8-10) had been completely rebuilt after a destructive event. An earlier construction phase, which is observed south of the centre of the courtyard (Fig. 2.1: Room 9), is covered by a later floor. - Taxel et al (2009:186-187)
  • The original arrangement of the courtyard was changed, probably due to the earthquake that struck the monastery at the end of Phase IIA. The walls of the entrance room or corridor were demolished down to their foundation course. The floor of this room/corridor, which was lower than those of the courtyards themselves, was raised to create a uniform-level platform in which were embedded the remains of the entrance room. - Taxel et al (2009:35)

Apse of the Church



  • Fallen masonry and subsequent repairs were observed in the southern part of the apse of the church, with its inner face remaining asymmetric. Since the damage is observed close to the foundations of the church it seems that the damage had a pervasive affect on the entire structure. - Taxel et al (2009:186-187)

Main Gate


  • The large, monolithic and nicely carved stones are placed in-situ but broken by a width wise crack into two pieces. Assuming the thresholds were carved from intact rocks without significant fractures, we can envision strong vertical acceleration, perhaps of the order of 1g, which caused the fracturing. Such strong shaking is known based on modern earthquakes to occur either near the epicentre of strong earthquakes (of the order of magnitude 7 and above) or in places with strong local amplification of seismic waves. - Taxel et al (2009:186-187)

Gatehouse


  • The remains which point to the architectural changes that took place here during Phase IIB are:

    1. The western part of the monastery’s southern wall, which included the main gate, is not built exactly on the same line as the rest of the wall. In addition, the level of the main gate’s threshold itself is 0.5-0.6 m higher than that of the path which leads to it from the south. This height difference did not, of course, allow comfortable passage from the path into the monastery

    2. The western edge of the gate ended without being connected to any of the other nearby walls, e.g., those of the church complex (Fig. 2.15). Actually, only a thin wall (W218; whose first course is built of three small coarsely-carved stones) abutted on it from the south and connected it to the church’s apse, while creating a small trapezoidal room (Room 33; 2.3-3.3×2.2 m)

    3. The path and the entrance corridor to its north was found covered with a fill rich in pottery sherds and other finds.

    At the time of the reconstruction, the gate was not only rebuilt along a somewhat different line than the rest of the southern wall, but also its threshold was raised.

Discussion

Schmuel Marco in Taxel et al (2009:186-187) suggested that seismic intensity may have reached IX (1 g) apparently largely based on the broken threshold of the Main Gate (shown in Fig. 2.24 above and not necessarily fractured in an earthquake) and rebuilding evidence which inferred wall collapses down to the foundations. Archaeoseismic evidence at the Monastery of Euthymius as reported by Hirschfeld (1993) showed evidence for a near total rebuild after it was presumably destroyed in one of the Jordan Valley Quake(s) of 659/660 CE. Although direct archaeoseismic evidence was not observed at the Monastery of Euthymius, the contemporary Maronite Chronicle reported that the Monastery of Euthymius collapsed during this earthquake - which supports the idea that a near total rebuild supports such a high level of local seismic intensity. However, the Monastery of Euthymius is closer to active Jordan Valley faults that seem to have broken during the Jordan Valley Quake(s) which means that Khirbet es-Suyyagh, further away from these faults, would have likely experienced lower levels of intensity during this event(s). This would explain why there were repairs at Khirbet es-Suyyagh rather than a complete rebuild. Given the distance between Khirbet es-Suyyagh and the active faults of Jordan Valley and the Dead Sea, Schmuel Marco in Taxel et al (2009:186-187) suggested that such an elevated intensity estimate (guesstimate ?) of IX (1 g) could be explained by a site effect or being above the hypocenter when the Quake struck (e..g in a blind thrust scenario). While a site effect is possible as it is described as being located on a spur, the Deformation Map (see in Figures above) suggests that North-South walls were preferentially damaged which is not what one would suspect above a hypocenter where inclination and collapse typically do not display directional patterns. Such directional patterns, which seem to be evident at Khirbet es-Suyyagh, are what one would expect at some distance form the epicenter (e.g. see Korzhenkov and Mazor, 1999).
