The 2021 Temebok earthquake and tsunami, also known as the Great Temebok Tsunami, was a shallow, large earthquake that struck with a magnitude of 8.4 30 miles north of Temebok, Qolaysia, on June 29th, 2021. It was the strongest quake in the Emmiria Sea since the 1932 Ascacia earthquake, and was felt as far away as Nebetia, Saint Croix and Bens, Alecburgh, and Zalluabed. This event was preceded by a sequence of foreshocks, the largest of which was a magnitude 6.1 tremor that occurred earlier that day.
Following the mainshock, a tsunami alert was issued for the coastal areas of northern Qolaysia, specifically Temebok. A seires of tsunamis struck Temebok, sweeping shore-lying houses and buildings on its way. The combined effects of the earthquake and tsunami led to the deaths of an estimated 11,340 people. This makes it the deadliest earthquake to strike Qolaysia, as well as the deadliest earthquake worldwide in 2021. The tsunami's height reached an estimated maximum of 4 to 7 metres (13 to 23 ft), striking the settlements of Hauialn, Lianan, and Cahai.
The earthquake caused major soil liquefaction in areas in and around Hauialn, leading to mudflows in which many buildings became submerged causing hundreds of deaths with many more missing. Additionally, Mount Abu began erupting as a result of the earthquake, with massive ash plumes disrupting aerial supply drops in the humanitarian relief effort.
