earthquakes

Description

earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. Seismic waves are produced when some form of energy stored in Earth’s crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and “slip.”

The most destructive earthquake

The earthquake of May 22, 1960, that struck the town of Valdivia in southern Chile is the most powerful ever recorded and has become known as the Great Chilean Earthquake. It is thought to have measured 9.5 on the moment magnitude scale (MMS).

Did you know... On the morning of November 1st, 1755 at 9:40, the Great Lisbon earthquake hit Portugal, as well as other parts of the Iberian Peninsula and Northwest Africa. Seismologists estimate the earthquake had a magnitude of 8.5 to 9.

The largest tsunami ever seen

On July 9, 1958, an earthquake along the Fairweather Fault in the Alaska loosened about 30.6 million cubic meters of rock high above the northeastern shore of Lituya Bay. This mass of rock plunged from an altitude of approximately 914 meters down into the waters of Gilbert Inlet. The impact force of the rockfall generated a local tsunami that crashed against the southwest shoreline of Gilbert Inlet.
