An earthquake is the shaking of the surface of Earth resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes may also be referred to as quakes, tremors, or temblors. The word tremor is also used for non-earthquake seismic rumbling . In its most general sense, an earthquake is any seismic event ...
The Chi-Chi earthquake [4] [5] [6] (later also known as the Jiji earthquake [a] or the great earthquake of September 21 [b] ), was a 7.3 M L or 7.7 M w earthquake which occurred in Jiji (Chi-Chi), Nantou County, Taiwan on 21 September 1999 at 01:47:12 local time.

The USGS provided a map of Asia in May 2008, which showed a total of 122 earthquakes occurring on the continent. The large red square near the center of the map depicts the 7.9 magnitude Chengdu quake in the Sichuan province. A USGS map shows that dozens of aftershocks occurred in a small region following the quake.
At least 19,747 people killed, 2,556 missing, 6,242 injured, 130,927 displaced and at least 332,395 buildings, 2,126 roads, 56 bridges and 26 railways destroyed or damaged by the earthquake and tsunami along the entire east coast of Honshu from Chiba to Aomori . 2011 Tōhoku earthquake and tsunami.

Seismology ( / saɪzˈmɒlədʒi, saɪs -/; from Ancient Greek σεισμός ( seismós) meaning "earthquake" and -λογία ( -logía) meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through the Earth or other planetary bodies. It also includes studies of ...
A major earthquake occurred in Christchurch on Tuesday 22 February 2011 at 12:51 p.m. local time (23:51 UTC, 21 February). [2] [10] The Mw 6.2 ( ML 6.3) earthquake struck the Canterbury region in the South Island, centred 6.7 kilometres (4.2 mi) south-east of the central business district. [11] It caused widespread damage across Christchurch ...
v. t. e. Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location. Magnitudes are usually determined from measurements of an earthquake's ...
