What the record says

NCEI’s account, from the sources it cites.

859 (possibly 861), November. Levantian Sea, Near East. A strong earthquake occurred on the coast from Antiochia to Akko. Large rockfalls and landslides. In the region of Samandagi (some references give Akko), the sea receded and then flooded the coast. (reference #2130)

859, November. Syrian coasts, near Samandag (iii). (reference #15, #20

859, November. Syrian Coasts near Samandag (iii). During one of the earthquakes of 245 AH, most probably in the month of Shaban (1 to 30 November 859 AD), a strong earthquake shook the Syrian coasts from Antiochia to Akka. As-Soyuti says that this earthquake shattered a mountain near Antiochia which fell into the sea together with 1005 houses and 90 villages. El-Macin, Abul-Faragi and Tabar add that the mountain was called Acraus or Rock and that it was closer to Akka rather than to Antiochia. All writers agree that when the mountain collapsed into the sea, the water retired and then returning surged he shores. (reference #24)
