Theophanes provides a date of 9 July and a probable
year of 551 CE. He recounts “a severe and frightful earthquake
throughout Palestine, Arabia, Mesopotamia, Syria, and
Phoenicia,” where “the following cities suffered: Tyre, Sidon,
Berytos, Tripolis, and Byblos.” He also reports a rockslide in
Botrys and that “the sea retreated [at an unspecified location]
one mile toward the deep and many ships were lost,” followed by
“a return of the sea to its own bed.”
