Introduction
ChatGPT Introduction

The Umayyad House in Jerash is a large elite residence built on level ground north of the South decumanus and in a quarter NE of the south Tetrapylon of Jerash. Excavations indicated that the house was in use from the 7th - 9th [?] centuries CE. The Umayyad House itself is notable for its well-preserved layout, with thick walls, reused Roman material, and an interior cistern. It remained in use for several generations and underwent internal modifications over time.

Notes by JW

Gawlikowski (1992:358) reports that the Umayyad house was built on level ground after an earthquake. They discuss its date of construction below:

The construction is well dated by the numismatic findings: on one hand coins of Constantius II (641-668), the last Byzantine coins having been used in Syria-Palestine, found within the fill (at depth and on the surface), and on the other hand Arab-Byzantine coins minted at Scythopolis (Beisan) and Jerash itself, "sealed" under the ground of the House. The exact dating of the latter coinage is not assured, but it is reasonable to place it around the middle of the 7th century, if not later (Bates, 1976). Therefore, I propose that the the earthquake that preceded construction as the one that struck Syria-Palestine in June 658, according to the testimony of Theophanes (Grumel 1958:479; Kallner-Amiran 1950-51:226). A recent discovery by J. Seigne corroborates our identification: the collapse of the vaulted corridor of the lower terrace of Zeus buries under the rubble a herd of goats; the age of a kid indicates that the cataclysm took place in May-June and moreover a Byzantine currency with an Arab countermark indicating the beginning of Muslim government (Seigne, unpublished report of 1984, kindly communicated by the author).
The archaeoseismic evidence is based on rebuilding evidence. No seismic effects from a 7th century CE earthquake are mentioned.

Gawlikowski (1992)

Chat GPT Summary of Archaeoseismic Evidence

Archaeoseismic evidence for a mid-7th century CE earthquake at the Umayyad house in Jerash is based on a clear phase of post-earthquake construction. According to Gawlikowski (1992:358), the house was built on level ground after an earthquake. It was bordered on both sides by high fill deposits, interpreted as clearance layers from this seismic destruction.

The event is dated through numismatic evidence: coins of Constans II (r. 641–668) were found within the underlying fill, while Arab-Byzantine coins from Scythopolis and Jerash were sealed beneath the house’s floors. The author proposes a terminus post quem in the mid-7th century, suggesting the structure was built after the June 658 earthquake [JW: slightly incorrect date for 659/660 CE Jordan Valley Quake(s)], described by Theophanes.

Additional supporting evidence comes from Jacques Seigne, who reported that a vaulted corridor on the lower terrace of the Zeus sanctuary collapsed, burying a herd of goats. The age of a kid and a coin with an Arab countermark place the event in May–June, shortly after the Muslim conquest.

No direct seismic damage (e.g., tilted walls, collapsed vaults, faults) from the 7th century was reported in the house itself. Instead, the archaeoseismic signal is inferred from stratigraphic evidence and intentional rebuilding.

Chat GPT Summary of Archaeoseismic Evidence

The excavators at the Umayyad house in Jerash found no conclusive evidence of destruction attributable to the 749 CE earthquake. Although the structure was Umayyad in plan and date, it showed no signs of structural collapse or violent damage that could be linked to a seismic event in the mid-8th century.

According to Gawlikowski (1992:358), the house’s interior was reoccupied and repurposed during the Abbasid period. Rooms were subdivided, new installations were added, and signs of domestic activity continued. The modifications were interpreted as signs of impoverishment rather than destruction and rebuilding.

The absence of a collapse layer or widespread clearing of debris suggests that this particular structure may have escaped major damage during the 749 CE earthquake. As such, the archaeoseismic evidence from this location is negative or absent for the 8th century.
