2006 Kuril Islands earthquake and tsunami – magnitude 8.3 earthquake, no injuries or fatalities anywhere; 2009 Samoa earthquake and tsunami – magnitude 8.0 earthquake with an epicenter 120 miles (190 km) southwest of American Samoa generated tsunami waves up to 16 feet (5 m), killing 34 people in American Samoa and causing extensive damage [39]
Even at low magnitudes, earthquakes can be felt in different cities than they originate in, just like Michigan's most recent 3.2-magnitude earthquake in 2020 with an epicenter about 2 miles ...
Millions of minor earthquakes occur every year worldwide, equating to hundreds every hour every day. [15] On the other hand, earthquakes of magnitude ≥8.0 occur about once a year, on average. [15] The largest recorded earthquake was the Great Chilean earthquake of May 22, 1960, which had a magnitude of 9.5 on the moment magnitude scale. [16]
Much of an earthquake's total energy as measured by M w is dissipated as friction (resulting in heating of the crust). [52] An earthquake's potential to cause strong ground shaking depends on the comparatively small fraction of energy radiated as seismic waves, and is better measured on the energy magnitude scale, M e. [53]
A magnitude 4.2 earthquake was felt widely across the nation's second largest city Friday and shook things off shelves near the epicenter in a small mountain community east of Los Angeles, but ...
Magnitude 4.2 earthquake rattles Idaho with shaking reported ...
2010 Mentawai earthquake and tsunami: VI. Strong: 0.12 g 0 (1.2 m/s 2) Felt by all, and many are frightened. Some heavy furniture is moved; a few instances of fallen plaster occur. Damage is slight. 2021 West Sulawesi earthquake, 2000 Enggano earthquake, and 1982 Baghlan earthquake: VII. Very strong: 0.22 g 0 (2.2 m/s 2)
An average of 25 earthquakes with magnitudes between 4.0 and 5.0 occur per year in California and Nevada, according to a recent three-year data sample. The earthquake occurred at a depth of 5.6 miles.
