State Seismological Bureau; the government agency responsible for monitoring earthquakes and coordinating disaster mitigation in China

seismology; the scientific study of earthquakes

An instrument used to detect and record the timing, intensity, and location of earthquakes.

an earthquake that can be felt by people; according to some systems, these are classified into six levels from micro to violent

seismic area; region or belt prone to earthquakes

seismologist; earthquake scientist

An instrument used to monitor earthquakes by automatically recording their intensity, depth, location, and time.

seismic sea wave; tsunami caused by an undersea earthquake

A measure of the degree of ground shaking and damage to buildings at a specific location caused by an earthquake. It is abbreviated as [[烈度|烈度|lie4 du4]] and is distinct from earthquake magnitude.

a logarithmic scale used by seismologists to measure the size of earthquakes in terms of the energy released

measure of the energy released by an earthquake as indicated by seismograph readings

A measurement of the amount of energy released by an earthquake; expressed as a single number that remains the same regardless of the location from which it is measured.

real-time report of earthquake data or an earthquake alert

The scale measuring the energy released by an earthquake; often abbreviated as [[震级|震級|zhen4 ji2]].

an earthquake of high intensity or magnitude

earthquake caused by the shifting or breaking of fault lines in the earth's crust

The most common and destructive type of earthquake, caused by the shifting of fault lines in the earth's crust; also called [[断层地震|斷層地震|duan4 ceng2 di4 zhen4]]

an earthquake with a focus located at a depth of less than 70 kilometers

seaquake; an underwater earthquake occurring at the bottom of the ocean that often causes significant changes to the seafloor structure

An earthquake occurring at a depth greater than 300 kilometers below the surface.

An earthquake caused by underground magma activity or a volcanic eruption, typically characterized by relatively low intensity and a limited impact area.

a series of many small earthquakes occurring in a localized area over a short period of time

Richter magnitude scale, used to measure the power of earthquakes; the numerical scale used to measure the magnitude of energy released by an earthquake

An earthquake where the focus occurs between 70 and 300 kilometers below the earth's surface

The massive earthquake of 1923 that devastated the Tokyo and Yokohama areas of Japan.

The massive earthquake that occurred in July 1976 in the Tangshan and Fengnan area of Hebei province; it is one of the deadliest earthquakes in history, with a death toll of approximately 250,000.

the massive earthquake that occurred in Sichuan province, China, in May 2008

a type of cloud formation that some people claim is a precursor to an earthquake, though it is not recognized by mainstream science

a facility equipped with instruments to detect and record earthquakes; seismograph station

seismological bureau; earthquake bureau

Measure of the local effects and damage caused by an earthquake at a specific location. It varies by distance from the epicenter and local geology; simplified as [[震度|震度|zhen4 du4]].

A temporary shelter used during or after an earthquake to protect people from potential building collapses or aftershocks

seismic zone; earthquake belt
