| January 18, 749|
| Bilad al-Sham province, Umayyad Caliphate
(modern-day Israel, Syria, Palestine (West Bank), Jordan) and Lebanon|
unknown, reportedly tens of thousands
A devastating earthquake known in the scientific literature as the Earthquake of 749 struck on January 18, 749 in areas of the Umayyad Caliphate, the worst affected being parts of Palestine and western Transjordan. The cities of Tiberias, Beit She'an, Hippos and Pella were largely destroyed while many other cities across the Levant were heavily damaged. The casualties numbered in the tens of thousands.
In Jewish sources this earthquake is known, in Hebrew, as רעש שביעית, Ra'ash Shevi'it, lit. "seventh noise", interpreted by scholars to mean The Earthquake of the Sabbatical Year, because 749 was a sabbatical year, literally "the seventh year" in the Jewish calendar.

According to historical sources, supported by archaeological findings, Scythopolis (Beit She'an), Tiberias, Capernaum, Hippos (Sussita), Jerash and Pella, suffered widespread damage. A Coptic priest from Alexandria reported that support beams had shifted in houses in Egypt and a Syrian priest wrote that a village near Mount Tabor had "moved a distance of four miles." Other sources reported tsunami in the Mediterranean Sea, several days of aftershocks in Damascus, and towns swallowed up in the earth. The town of Umm el Kanatir and its ancient synagogue were destroyed.
Historical sources describe how the death toll in Jerusalem numbered in the thousands. Many buildings, among them the Al-Aqsa Mosque, were severely damaged. However, some caveats are required. The view of the severity of the damage provoked by the 749 quake is contested by new research. Earlier claims that the large Umayyad administrative buildings south of the Al-Aqsa Mosque were so badly damaged that they were abandoned and used as stone quarries and sources of lime, lime kilns being found at the site, is reportedly wrong, the buildings staying in use until the 1033 earthquake. Similarly, the new Arab capital city at Ramla only shows minimal signs of damage.
"Ra'ash shvi'it" is mentioned in piyyutim (Jewish liturgical poems). Some rabbis believe the earthquake struck in a Sabbatical year, in which case, the translation of the term would be "earthquake of the seventh year".
