Migowski et. al. (2004) dated a small seismite (0.5 cm. thickness) from the En Gedi core to ~90 AD. There are no known historical reports of an earthquake in the vicinity of the Dead Sea during this time.

Textual Evidence

Sieberg (1932a or 1932 b) apparently lists an earthquake in Syria with destruction in Antioch between 84 and 92 AD but Sieberg (1932a or 1932 b) did not cite a source. Sbeinati et. al. (2005) duplicated Sieberg’s catalog entry with the following description
82-94 Antioch: VI-VII, Syria. Aftershocks.

Seismological compilations
Sieberg (1932): between 82-94 A.D., a strong widespread earthquake struck Syria causing destruction of many houses at Antioch. Shocks lasted for 40 days.
Karcz and Lom (1987) noted/discovered that Sieberg (1932a and 1932b) included some of Willis’(1928) uncorrected A.H. [1] dates from the Arabic source as-Soyuti. This indicates that some of Sieberg’s (1932a and 1932b) entries like Willis (1928) before him are approximately 622 years too old [2]. An online calenderic conversion of Sieberg’s 94 date leads to ~713 AD [3].

Ambraseys (2009) lists an earthquake in Northern Syria in 713 AD and cites one source, al-Yaq’ ubi, who records an earthquake that lasted 40 mornings and occurred in A.H. year 94. Another Arabic source (al-Isfah) stated that the earthquake lasted 40 days and destroyed many houses in Antioch. Finally, as-Soyuti, provided similar information about 40 days of shaking and destruction of buildings in Antioch. As-Soyuti dates this earthquake to 94 A.H. Based on this information, it is clear that the 82 – 94 AD catalog entry of Sieberg (1932a or 1932b) and Sbeinati et. al. (2005) is incorrectly dated and occurred in 713 AD. Needless to say, it did not create a ~90 AD Dead Sea seismite indicating that the mysterious source of this potential seismite endures.

Archeoseismic Evidence

Paleoseismic Evidence

En Gedi (DSEn)

Migowski et. al. (2004) dated a small seismite (0.5 cm. thickness) at a depth of 266 cm. (2.66 m) to ~90 AD.

Other locations

Although no other researchers dated a seismite to ~90 AD, they did date seismites and seismic events around this time. Consult the Paleoseismic Section of the Jewish War Quake for more information.

[1] A.H. = Anno Hegirae in Latin, i.e. "in the year of the Hejira”. Hejira refers to the migration of Mohammed and his followers from Mecca to Yathrib (later renamed Medina) in 622 AD. This migration marks the beginning of the Islamic calendar.
