Johannes Malalas wrote a contemporaneous account
that assigns the event to 551 CE. He records that “a severe
and tremendous earthquake occurred throughout the land of
Palestine, in Arabia and in the land of Mesopotamia,
Antioch, Phoenice Maritima and Phoenice Libanensis,” where
“the following cities suffered: Tyre, Sidon, Berytus,
Tripolis, Byblus, Botrys and parts of other cities.”
Malalas also notes a rockslide in Botrys and that “at the
time of the earthquake the sea retreated [at an unspecified
location] for a mile and many ships were destroyed,” followed
by the sea being “restored to its original bed.”
