On August 17, 1983, at 20:17 PST (UTC+08:00), an earthquake struck the island of Luzon in the Philippines. The shock had a surface wave magnitude of 6.5 and a maximum Mercalli intensity of VIII (Severe), killing 16 people and injuring 47. Seven towns were damaged, several buildings collapsed, and electricity was cut off in Laoag. Features like sand volcanoes and cracks formed during the quake.

A landslide occurred at about 05:38 local time on 24 June 2017 in Diexi Town, Mao County, Sichuan Province in south-western China. It destroyed 40 homes in Xinmo Village and killed 10 people, with a further 73 people missing, as of 27 June. A second smaller landslide at around 17:19 impeded rescue efforts.

The 1998 Papua New Guinea earthquake occurred on July 17 with a moment magnitude of 7.0 and a maximum Mercalli intensity of VIII (Severe). The event occurred on a reverse fault near the north coast region of Papua New Guinea, 25 kilometers (16 mi) from the coast near Aitape, and caused a large undersea landslide which caused a tsunami that hit the coast, killing between at least 2,183 and 2,700 people and injuring thousands.

An earthquake occurred in southern Mongolia on December 4, 1957, measuring Mw 7.8–8.1 and assigned XII (Extreme) on the Modified Mercalli intensity scale. Surface faulting was observed in the aftermath with peak vertical and horizontal scarp reaching 9 m (30 ft). Because of the extremely sparse population in the area, this event, despite its magnitude, was not catastrophic. However, 30 people died and the towns of Dzun Bogd, Bayan-leg and Baruin Bogd were completely destroyed.
