While earthquakes are most common along the fault lines of tectonic plates—of which there are seven major ones in the world—the seismic quakes can actually hit anywhere, at any time, according ...
In its most general sense, the word earthquake is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear tests. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the epicenter.
The USGS estimated that the earthquake could cause economic losses measuring between 1–10% of Vanuatu's GDP. [19] The United Nations Office for the Coordination of Humanitarian Affairs estimated that 116,000 people had been directly affected by the earthquake, [43] equivalent to a third of Vanuatu's population.

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 ...
