Earthquakes are common on the West Coast, with multiple plate boundaries like the San Andreas fault making geologic activity more likely. They are rarer on the East Coast, but they do happen ...
In the (low seismicity) United Kingdom, for example, it has been calculated that the average recurrences are: an earthquake of 3.7–4.6 every year, an earthquake of 4.7–5.5 every 10 years, and an earthquake of 5.6 or larger every 100 years. [42] This is an example of the Gutenberg–Richter law.
An earthquake is a phenomenon that results from the sudden release of stored energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes may manifest themselves by a shaking or displacement of the ground and sometimes cause tsunamis, which may lead to loss of life and destruction of property. An earthquake is ...
A complete earthquake cycle can be divided into interseismic, preseismic, coseismic and postseismic periods. [1] During the interseismic period, stress accumulates on a locked fault due to plate motion. [2] In the preseismic period, this stress is approaching the rupture limit, and some earthquake precursors may occur. [1]

Turkey is reeling after being hit by two powerful earthquakes in quick succession on Monday morning.. The first, the worst to strike the country since the Erzincan quake of 1939, measured 7.8 on ...
An earthquake is caused by a sudden slip on a fault. Tectonic plates are always slowly moving, but they can get stuck at their edges due to friction.When the stress on the edge of a tectonic plate overcomes the friction, there is an earthquake that releases energy in waves that travel through the Earth's crust and cause the shaking that is felt.
Earthquakes (6.0+ M w) between 1900 and 2017. Earthquakes are caused by movements within the Earth's crust and uppermost mantle. They range from weak events detectable only by seismometers, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history. Below, earthquakes are listed by period ...
