Detailed explanation-1: -Earthquake shaking causes movement or dam-age of equipment and contents. This movement can result in released flammable gases or liquids and other combustible material coming into contact with ignition sources, such as open flames or electrical arcing.
Detailed explanation-2: -Ground shaking is the vibration of the ground during an earthquake. The shaking triggers other hazards such as liquefaction and landslides. Most earthquake damage results from the seismic waves passing beneath buildings, roads, and other structures.
Detailed explanation-3: -Earthquakes are caused by a sudden release of stress along faults in the earth’s crust. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake.
Detailed explanation-4: -Earthquakes can be induced by a wide range of causes including impoundment of reservoirs, surface and underground mining, withdrawal of fluids and gas from the subsurface, and injection of fluids into underground formations.
