An earthquake can range from a mild tremor to a large-scale movement causing extensive damage over a wide area. Major earthquakes can be devastating, breaking electrical lines or gas pipes and causing fires. Tremors during earthquakes can also cause soil liquefaction by making saturated soil lose strength and transform from solid to liquid. Some historical earthquakes in India include the 1905 Kangra earthquake that killed 20,000 people, and the 1934 Bihar earthquake that killed nearly 11,000. The 2001 Bhuj earthquake killed over 13,000 and destroyed 800,000 homes and damaged roads and bridges.
