Ambraseys (2009) states that "Russell ... argues that Pella and Ramat Rahel were damaged" in the 551 CE Beirut Quake, where sources indicate limited destruction south of Tyre. Ambraseys continued that "Pella is 100 km southeast of Tyre" and "Ramat Rahel is just south of Jerusalem", making it "impossible that this earthquake damaged the latter." Ambraseys further adds that "Ambraseys et al. (1994, 24–25) wrongly place the epicentral region of this event in the Jordan Rift Valley," attributing this mislocation to "the bias of information from the debatable archaeological evidence in Russell (1985)."
