Agathias of Myrina wrote a contemporaneous account
of the earthquake, as he was about twenty-one years old and
living in Alexandria, Egypt when it occurred. Although
Agathias combined accounts of other earthquakes – such as the
554 CE Constantinople event – into his narrative, creating
some chronological ambiguity, it is possible to isolate his
description of the
551 CE Beirut Quake to several
details: the destruction at Beirut, the transfer of the law
school from Beirut to Sidon, an earthquake occurring in the
summer, and probably the “slight tremor” felt in Alexandria.
Ambraseys (2009) noted that if the
law school was temporarily relocated to Sidon, the lesser
damage there would imply an epicenter located nearer to Beirut.
