Ben-Menahem (1979:259) and
Ben-Menahem (1991:20198) report that three structures in the Araba were fortified to withstand earthquakes between the years 9 BCE and 50 CE.
This could reflect indirect evidence of a recent earthquake; primarily due to a Nabatean pattern of quickly repairing structures after earthquakes during this prosperous period.
He locates these structures in Petra, Tel el Haliefe, and Wadi Ramm. His references were
Avi-Yonah (1975) Vol III and IV and
Tel el Haliefe site does not appear to contain any evidence for fortification of structures between 9 BCE and 50 CE. Pratico and DiVito (1993), Avi-Yonah (1975), and Glueck (1940) all state that the site appears to have been abandoned by 4th or 3rd century BCE at the latest.
