893 Armenia earthquake

978 Taheri (Siraf) earthquake
The 978 Siraf earthquake struck the port city of Siraf, near present Taheri in Bushehr Province, Iran, on 17 June 978, damaging most of its houses and contributing to the port's decline.
Aftershock
An aftershock is a smaller earthquake that follows a larger mainshock in the same area. Aftershock sequences follow statistical patterns, allowing seismologists to forecast them.
April 2015 Nepal earthquake
The April 2015 Nepal earthquake, known as the Gorkha earthquake, was a magnitude 7.8 quake that struck central Nepal on April 25, 2015, killing nearly 9,000 people.
Earthquake
An earthquake, also called an earth tremor, is a shaking of the ground caused by a sudden slip on a fault, releasing energy as seismic waves through the crust.
Earthquake early warning system
An earthquake early warning (EEW) system detects the first, fast seismic waves of an earthquake in progress, alerting people seconds before slower, damaging shaking arrives.
Earthquake light
Earthquake light, also called earthquake lightning, is an atmospheric luminous phenomenon, seen as sheet lightning, balls of light, or glows, reported before, during, and after earthquakes since antiquity.
Earthquake prediction
Earthquake prediction is the claim that the date, location, and magnitude of a future earthquake can be specified in advance, which the USGS says is not yet possible.
Earthquake zones of India
The earthquake zones of India are four seismic hazard zones, II to V, defined by the Bureau of Indian Standards, with Zone V the most severe.
Elastic-rebound theory
Elastic-rebound theory explains earthquakes as the sudden release of elastic strain that builds up in rock around a locked fault, proposed by Harry Fielding Reid after the 1906 San Francisco earthquake.
Epicenter
The epicenter, also spelled epicentre, is the point on the Earth's surface directly above the hypocenter, where an earthquake's rupture begins at depth. It is located by triangulation among seismographs.
European macroseismic scale
The European Macroseismic Scale 1998 (EMS-98) is a twelve-degree seismic intensity scale, developed from the MSK-64 scale and used as the standard for rating earthquake shaking in European countries.
Fault scarp
A fault scarp is a step in the ground surface caused by slip on a fault, formed when earthquake rupture breaks through to the surface, and serves as primary evidence of past earthquakes.
Great Hanshin earthquake (阪神・淡路大震災)
The Great Hanshin earthquake, also known as the Kobe earthquake, was a magnitude 7.3 quake that struck Kobe, Japan, on January 17, 1995, killing 6,434 people.
Hakuhō earthquake
The Hakuhō earthquake (白鳳地震, also called the Tenmu earthquake) was a magnitude 8.3 earthquake that struck Japan on 29 November 684, the oldest recorded great earthquake along the Nankai Trough.
Jōgan earthquake
The Jōgan earthquake (貞観地震) was a great earthquake and tsunami that struck Mutsu Province in northern Japan on 9 July 869, drowning roughly 1,000 people on the Sendai plain.
Kiyoo Wadati
Kiyoo Wadati (和達清夫, 1902–1995) was a Japanese seismologist who established that earthquakes occur at depths of several hundred kilometers, and whose name is attached to the Wadati–Benioff zone.
