Volcanic eruptions release a huge amount of lava and magmatic materialIn areas of active volcanoes, this can trigger earthquakes and is called a Volcanic earthquake.Tsunami waves do not cause earthquakes but they are the result of an earthquake.Areas with large reservoirs and dams are prone to reservoir induced earthquakesMany times in areas of intense mining the underground roof collapses which give rise to collapse earthquakesThe explosion of nuclear devices can result in the release of a large amount of energy which triggers explosion earthquakes.Additional InformationAn earthquake in simple words is the shaking of the earth.It is caused due to the release of energy, which generates waves that travel in all directions.The vibrations called seismic waves are generated from earthquakes that travel through the Earth and are recorded on instruments called seismographs.The location below the earths surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicentre.
