1114 CE Jerusalem Quakes

All of the buildings were destroyed at the end of Phase IIb, probably by the strong earthquake that struck the region in 1033/4 [i.e., the 11th century CE Palestine Quakes]; both historical sources and the remains in other cities attest to this event. Following the earthquake, some of the buildings were left in ruins, but others were rebuilt. The buildings in Area A, for example, was never restored: the columns that had collapsed in the earthquake were discovered toppled on the floors of the courtyards belonging to the Phase IIb building.

The archaeological data testify to an uninterrupted occupancy from eighth century until 1000 A.D. of the Hisham palace (Whitcomb, 1988). Therefore, if earthquakes occurred in this time period, the effects should not have implied a total destruction with consequent occupancy contraction or abandonment. Toppled walls and columns in the central court cover debris containing 750-850 A.D. old ceramic shards (Whitcomb, 1988). Recently unearthed collapses north of the court confirm a widespread destruction after the eighth century (Jericho Mafjar Project - The Oriental Institute at the University of Chicago). These elements support the action of a destructive shaking event at the site later than the 749 A.D. earthquake. The two well-constrained, major historical earthquakes recognized in the southern Jordan Valley are the 749 and 1033 A.D. (Table 1; Marco et al (2003); Guidoboni and Comastri, 2005). We assign an IX—X intensity degree to the here-recorded Hisham damage, whereas a VII degree has been attributed to the 749 A.D. earthquake at the site (Marco et al, 2003). Furthermore, Whitcomb (1988) defines an increment of occupation of the palace between 900 and 1000 A.D. followed by a successive occupation in the 1200-1400 A.D. time span. On the basis of the above, and because no pottery remains are instead associated with the 1000-1200 A.D. period at Hisham palace (Whitcomb, 1988), we suggest a temporary, significant contraction or abandonment of the site as consequence of a severe destruction in the eleventh century.

A massive stone collapse had covered the floors of the different architectural units. The many broken pottery vessels date the collapse of the building to the Abbasid period or to the beginning of the Fatimid period (10th–11th century CE)

We believe that filling up the cavea and orchestra of the theater happened parallel with the construction of the enclosing wall that essentially put all of the remaining building underground. Underground facilities are significantly less vulnerable to seismic excitation than that above-ground buildings (Hashash et aL, 2001). Understandably, when each wall and arch are supported by embedding sediment (dump in Beit-Ras), the observed deformations of the excavated theater mostly cannot develop unless unsupported. Therefore, evidence of damage due to any subsequent events, such as A.D. 551, 634, 659, and 749, cannot be observed, because the possibility of collapse of buried structures is not plausible. However, potential collapse of other above-ground structures within the site of Beit-Ras cannot be ignored, such as the upper elements of the theater's structures, which were still exposed after the filling of the theater with debris. Several observations indicated that many collapsed elements of the upper parts of the theater were mixed with the debris, as documented in excavation reports by Al-Shami (2003, 2004). Another example suggesting the effect of the later events, such as that of A.D. 749. Mlynarczyk (2017) attributed the collapse of some sections of the city wall of Beit-Ras to this event, based on the concentration of collapsed ashlars and the age of collected pottery from two trenches excavated to the west of the theater structure.

The basalt masonry in the upper left suggests a later local collapse and repair phase, where the basalt courses are overlaying the marly-chalky limestone to the left of the walled arched eastern gate.
