In general sense, the word earthquake is used to describe any seismic event, a natural event or an event caused by humans - that produces seismic waves. Earthquakes are often caused by geological faults, large amounts of gas migration, mainly methane deep inside the earth, volcanoes, landslides, and nuclear tests are the main faults. The starting point of the earthquake is called center or hypocenter. The word epicenter means the point just above the ground level. Earthquakes often occur in volcanic regions as well, for two reasons there are tectonic faults and lava movements in volcanoes. Such earthquakes can be an early warning of volcanic eruptions. Many times a series of earthquakes occur in the form of earthquake storms, where earthquakes cause group faults, redistribution of the stress of the former shock in each shock. This is similar to the latter shock but is the trailing part of the blame, these storms occur over a period of several years. So, take this quiz and increase your knowledge about the world earthquake.
