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 earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (M w) that can exceed 9.0. [1] [2] Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes. [3]
The U.S. Geological Survey said the earthquake struck at 9:33 a.m. local time (12:33 p.m. GMT), and its epicenter was 42 kilometers (26 miles) southwest of Huasco, a city in Chile’s Atacama region.
It is the largest earthquake to hit the state since 2014. [332] On Hutchinson Island, the earthquake caused land to slump into the Savannah River, seriously damaging the parking garage of a dock situated above. [333] — — 19 [334] Japan, Ishikawa, 61 km (38 mi) north northeast of Nanao: 5.1 10.0 VI
A magnitude 4.3 earthquake struck West Bengal, India on February 6, killing 1 person. [9] A magnitude 6.9 earthquake occurred in the Northern Atlantic Ocean on February 8. [21] A magnitude 6.6 earthquake struck the South Sandwich Islands on February 10. [22] A magnitude 6.5 earthquake struck Oaxaca, Mexico on February 12. [23]
Large earthquakes also occurred near the junction in northern California in previous Decembers, according to the geological survey. There were two, a 6.1 and 6.0, near Petrolia in 2021 and a 6.4 ...
The 2003 San Simeon earthquake struck at 11:15 PST (19:15 UTC) on December 22 on the Central Coast of California, about 7 miles (11 km) northeast of San Simeon. Probably centered in the Oceanic fault zone within the Santa Lucia Mountains , it was caused by thrust faulting and the rupture propagated southeast from the hypocenter for 12 miles (19 ...
