Archaeological and textual evidence indicates that a destructive earthquake affected the area of the Temple of Allat at Palmyra in the 10th or 11th century CE, resulting in the final destruction of a domestic structure rebuilt from the Praetorium. According to Kowalski (1994:59), the house built over the former Praetorium on the Temple of Allat terrace was ultimately destroyed by an earthquake, following a phase of earlier abandonment. The structure appears to have fallen out of use by the 9th century CE, consistent with wider abandonment in this sector of the city. Its main entrance was walled up, and the building remained unoccupied until its destruction. After the earthquake, Kowalski (1994:59) reports that the "ruin was buried in earth."

Kowalski (1994:59), suggests that the caustive earthquake was the 1042/3 CE Tadmur and Baalbek Earthquake while noting that Colledge (1976:22) placed the earthquake in the 10th century CE. Kowalski (1994:59 n.20) also claims that the historian Ibn Taghri Birdi recorded an earthquake in A.H. 434, corresponding to 1042/3 CE, in his chronicle An-Nujum al-Zahira. Neither Ambraseys (2009) nor Guidoboni and Comastri (2005) mention Ibn Taghri Birdi as a source for the 1042/3 CE Tadmur and Baalbek Earthquake, listing as‑Suyūṭī instead.
