Facts About Earthquakes

Earthquakes are movements of the Earth’s surface, often as a result of a fault, or fracture deep in the crust. They occur commonly in some parts of the world, as compared to others.

 An earthquake occurs when there is a sudden movement in the rocks underground.

 Earthquakes happen where the plates of the earth’s crust are moving in different directions. The rocks in the crust begin to bend because of the pressure, just as a stick would snap if you keep bending it.

 If the earthquake happens under the ocean, then it results in waves that travel through the water. They move in the same way that the ripples travel out from a pebble thrown into a pond. Waves made by earthquakes are called ‘tsunami’.

 Given here are some recorded facts about earthquakes:
 1. The worst ever earthquake to have occurred in the Middle East and North Africa was on 20th May 1202. This has been considered to be the worst ever known earthquake in which about 10,00,000 people lost there lives.

 2. On 2nd February 1556, 8,20,000 people were killed in the earthquake that rocked Shenshi in China.

 3. On 11th October 1737, a deadly earthquake is known to have rocked Calcutta in India, killing about 3,00,000 people.

 4. On 16th December 1920, an earthquake and landslides in Kansu Province left approximately 1,80,000 people dead.

 5. An earthquake in Tang-shan, China, on 28th July 1976, left approximately 2,42,000 people dead.

 6. An earthquake that rocked Kashmir going up to parts of Pakistan, on 11th October 2005, caused the death of approximately 1,00,000 people.

 7. An earthquake does not last more than a minute, two; however, an earthquake that rocked Alaska, on 27th March 1964, lasted for approximately 5 minutes. Thankfully, only 131 deaths happened. However, the damage done amounted to approximately 450,000,000 Dollars.

 8. On 26th December 2004, a Tsunami was created by an undersea earthquake, which caused catastrophic floods in Indonesia, Sri Lanka, Myanmar, The Maldives, Malaysia, India and a few parts of Africa, leaving over 2,83,000 people dead.
