Earthquakes (M6.0+) since 1900 through 2017 Earthquakes of magnitude 8.0 and greater from 1900 to 2018. The apparent 3D volumes of the bubbles are linearly proportional to their respective fatalities. [1] One of the most devastating earthquakes in recorded history was the 1556 Shaanxi earthquake, which occurred on 23 January 1556 in Shaanxi, China.
Earthquakes are common on the West Coast, with multiple plate boundaries like the San Andreas fault making geologic activity more likely. They are rarer on the East Coast, but they do happen .
A type of seismic zone is a Wadati–Benioff zone which corresponds with the down-going slab in a subduction zone. [2] The world's greatest seismic belt, known as the Circum-Pacific seismic belt, [3] is where a majority of the Earth's quakes occur.

About 55 earthquakes a day – 20,000 a year – are recorded by the National Earthquake Information Center.Most are tiny and barely noticed by people living where they happen. But some are strong ...
Most earthquakes occur at the boundaries between tectonic plates, such as the 'Ring of Fire' around the Pacific Ocean plate. Earthquakes within a tectonic plate, like those in the eastern U.S., do ...
Focal depths of earthquakes occurring in continental crust mostly range from 2 to 20 kilometers (1.2 to 12.4 mi). [8] Continental earthquakes below 20 km (12 mi) are rare whereas in subduction zone earthquakes can originate at depths deeper than 600 km (370 mi).
Earthquakes frequently occur in the region at depths of up to 670 kilometres (420 mi) beneath the surface. [13] Several large earthquakes have taken place here, including the M w 8.2 1994 Bolivia earthquake (631 km deep), the M w 8.0 1970 Colombia earthquake (645 km deep), and M w 7.9 1922 Peru earthquake (475 km deep).
