Topic/Area of Geology: Earthquakes Fact: Earthquakes occur when two blocks of the earth's crust suddenly slip past each other. The blocks of the crust are constantly moving due to the slow but continuous movement of tectonic plates. The energy released in the form of seismic waves during an earthquake can be measured using different magnitude scales, such as the Richter scale or the moment magnitude scale. The largest earthquake ever recorded was the 1960 Chilean earthquake, which had a magnitude of 9.5 on the moment magnitude scale. Earthquakes can cause considerable damage to buildings, roads, and other infrastructure, as well as triggering landslides and tsunamis. Scientists continue to study earthquakes and how they occur in order to improve our understanding of the Earth's geology and to predict and mitigate the risks associated with seismic activity.
