Maps and Plans Chronology
Beirut Conversion Quake Tsunami (?) - 347/348/349 CE

Several catalogs ( e.g. Ambraseys, 1962, Antonopoulos, 1979, Antonopoulos, 1980a, and Sbeinati et. al., 2005) consider the possibility that a tsunami was associated with The Beirut Conversion Quake of 347/348/349 CE. While this is valid speculation, none of the historical sources mention a tsunami. The way a tsunami entered these catalogs is likely via Sieberg (1932b) who mentioned damage on the Island of Arwad due to this earthquake.

Translation : Earthquake on the Syrian Coast where Beirut and Arwad Island suffered.
The Island of Arwad is approximately 100 km. from Beirut. In the apparently larger 551 CE Beirut Quake, Sieberg (1932b) mentions widespread destruction in Beirut and that the earthquake was only felt in the Island of Arwad. He does not say it suffered. Based on this, if Sieberg (1932b) mentions suffering on the Island of Arwad due to the Beirut Conversion Quake, the suffering would likely be due to a tsunami rather than seismic shaking. Unfortunately, Sieberg (1932b) did not list his sources. As neither of the sources (Theophanes and Cedrenus) mention damage on the Island of Arwad, this tsunami report, though possible, is likely a false one. Salamon et. al. (2011) concurred that this tsunami report was probably false.
