Subsequently, one may also ask, how do earthquakes happen National Geographic?
Earthquakes are the result of pressure -- specifically, pressure caused by extreme stress in the Earth's crust. That stress can be caused by volcanic activity or even manmade activities in certain areas. However, most earthquake-inducing stress is caused by the movement of tectonic plates.
Also Know, can a 7.1 earthquake cause a tsunami? It should be noted that not all earthquakes generate tsunamis. Usually, it takes an earthquake with a Richter magnitude exceeding 7.5 to produce a destructive tsunami. Most tsunamis are generated by shallow, great earthquakes at subductions zones.
Also, how does earthquake occur?
An earthquake is caused by a sudden slip on a fault. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the North American Plate.
Where do earthquakes occur most often?
- The world's greatest earthquake belt, the circum-Pacific seismic belt, is found along the rim of the Pacific Ocean, where about 81 percent of our planet's largest earthquakes occur.
- The Alpide earthquake belt extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic.
