The 2021 Haiti earthquake was the largest to strike the country since the 1842 Cap-Haïtien earthquake. More than 138,000 buildings were damaged or destroyed, most of them in Les Cayes and Nippes. 2,248 people were killed, 12,763 others were injured and 329 people remained missing. It is the deadliest earthquake of 2021. [338] 2,248 12,763 16 [339]
The following is a list of significant earthquakes from 2021–2030, listing earthquakes of magnitude 7 and above, or which caused human fatalities. Deaths due to earthquake-caused tsunamis are included.

The earthquake occurred as a result of oblique-reverse faulting on an 80 km (50 mi) section of the Enriquillo–Plantain Garden fault zone, [20] 125 km (78 mi; 67 nmi) west of the Haitian capital Port-au-Prince, consistent with its location and the observed focal mechanism. It had an estimated hypocentral depth of 10.0 km (6.2 mi). [1]
The earthquake ruptured an area of about 120 mi × 60 mi (193 km × 97 km), equal to about 7,200 sq mi (19,000 km 2). The estimated maximum slip along this fault surface was about 3 to 4 m (9.8 to 13.1 ft). [30] The earthquake appears to have only partially ruptured the Shumagin segment of the subduction zone, at 75%.
The 2021 South Sandwich Islands earthquakes were a pair of powerful earthquakes, followed by many strong aftershocks which struck along the South Sandwich Trench in August 2021. The quakes measured 7.5 and 8.1 on the moment magnitude scale , according to the United States Geological Survey .
The earthquake occurred at a relatively shallow depth, only 20 kilometres (12 mi) below the surface, which would have amplified the shaking effect. [7] Earthquakes of this size according to the U.S. Geological Survey are 40 km × 20 km (25 mi × 12 mi) in rupture size. [1] The earthquake occurred at the southern extent of the Guerrero Gap.
A moment magnitude (M w) 6.2 earthquake struck Majene Regency in West Sulawesi, Indonesia, on 15 January 2021, at 02:28 WITA (18:28 UTC). The reverse faulting shock initiated at 18.0 km (11.2 mi) depth with an epicenter inland, located 32 km (20 mi) south of Mamuju. It was preceded by a M w 5.7 foreshock several hours prior.
