Earthquakes occur most often along the edges of oceanic and continental plates. Oceanic plates are the large pieces of the Earth's crust that are located beneath the oceans. Continental plates hold the Earth's large land masses.
Earthquakes occur when the Earth's plates move and rub against or bump into each other. Quakes occur most frequently along the edges of plates, but they are also common along faults, which can be far from the edge of a plate. Faults are cracks where smaller sections of the plate move against each other. Cracks may be defined as normal, reverse or strike-slip faults. One of the most well-known faults, the San Andreas Fault, is a strike-slip fault.Learn More
The Richter Scale measures the magnitude of an earthquake. The scale was created in 1935 by American seismologist and physicist Charles F. Richter.Full Answer >
Seismic activity is described by geologists as an elastic wave traveling through the Earth following an earthquake or other geological disturbance. Seismic activity encompasses the frequency, size and type of earthquake, according to the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization, which monitors seismic activity throughout the world.Full Answer >
An earthquake is defined as a series of vibrations within the earth's crust that are caused by the rupture of its rocks. This rupture is due to the gradual accumulation of elastic strain within the crust.Full Answer >
Seismology is the study of waves of energy, especially earthquakes, that move through and around the Earth. These waves of energy are called seismic waves, and the scientists who study them are called seismologists.Full Answer >
