Ground movements that occur when blocks of rock in the Earth move suddenly and release energy.

A scientific scale for measuring the intensity of an earthquake's effects a specific location.

A series of extremely long waves that can travel across the ocean at speeds of up to 800 km/h.

A scientific scale for measuring the magnitude of an earthquake based on the amplification of seismic waves. (Recorded by a seismograph.)

Small earthquakes that occur in the main earthquake's area.

A crack in the Earth's crust alongside the movement of rock chunks.

P waves (Primary waves)

Squeezes rock in the same direction the wave is travelling.

S waves (Secondary waves)

The moving of rock side to side.

The study of seismic waves and seismology.

The movement of a mass of rock, debris, or the Earth down a slope by gravity.

An opening within a planet where molten rock, gas, and ash erupt from beneath the surface, often leading up to the formation of a mountain.

The point on the Earth's surface directly above the origin of an earthquake.

A scientific instrument that measures, records and analyzes the details of earthquakes; often relating to force and duration.

A point where light, sound, and energy converge.

A string of volcanoes amongst seismic activity or earthquakes, located around the edges of the Pacific Coean.

When loose soil behaves like a fluid while losing strength. (Due to stress and shaking from earthquake activity.) To summarize: The transition of a solid substance to a liquid.
