Geological setting
The Dead Sea Transform (DST) is a 1,000 km (620 mi) transform fault that spans from the Red Sea in the south to the East Anatolian Fault in Turkey to the north. The southern extent of the DST is known as the Wadi Araba fault (after the Arabah valley). This portion of the DST runs 160 kilometers (99 mi) from north of Aqaba/Eilat to south of the Dead Sea and has a slip rate of 4 mm ±2 mm per year.[5] The temporal pattern of large events has not been clarified yet, with only four well-documented large earthquakes reported in the Araba valley over the last few thousands of years occurring in 1068, 1212, 1293 and 1458 CE.[2]
In 1998, Zilberman thought to locate the epicentre of the 1068 event at the Avrona playa, i.e. in the southern part of the Arava Valley.[6][7] Ambraseys (2005) separates between a March event with the epicentre near Tabuk, and a May event closer to Ramla.[1]

Other events
In addition to the event in 1068, the southern portion of the DST has experienced three other historical events (all having an estimated magnitude of 6.5–7.0) with two in the northern section near the Dead Sea, and one closer to Aqaba. The event in 1212 caused significant damage to towns in the Arabah Valley as well as the destruction of a church on the Sinai Peninsula. In 1293, near the southern portion of the Dead Sea, an earthquake destroyed three towers of a castle[
