biology of earthquake
Answers
Answer:
An earthquake is an abrupt, rapid vibration of the earth, caused by the sudden release of accumulated potential energy into the kinetic energy of motion. Most earthquakes are produced along faults, tectonic plates, boundary zones, or along the mid-oceanic ridges. More than 150,000 shakes strong enough to be felt by humans arise each year worldwide. An earthquake is usually followed by a series of aftershocks because of the continued release of frictional stress. Most aftershocks are smaller than the main earthquake, but they can still cause considerable damage to already weakened natural and human constructed features. Approximately 13 million people have died as the result of earthquakes during the past 4,000 years.
Answer:
Explanation:
The boundary of tectonic plates along which failure occurs is called the fault plane. When the failure at the fault plane results in a violent displacement of the Earth's crust, the elastic strain energy is released and seismic waves are radiated, thus causing an earthquake.
