The Umayyad Congregational Mosque of Jerash was uncovered in the 2000s and lies in the southern half of the city, just north of the Oval Plaza. Rattenborg and Blanke (2017) and Walmsley and Damgaard (2005) both date its construction to around 725 CE. Blanke and Walmsley (2022:95–97) state that “in 749, after only a few decades of use, the mosque along with most of Jarash’s urban fabric was devastated by one or more massive seismic events.” Following these events, the mosque was rebuilt to its former dimensions, but its main entrance was blocked, as was its central miḥrāb. The only archaeoseismic evidence for mid-8th-century earthquakes in the Umayyad Mosque consists of rebuilding evidence.
