Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock.

earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger


Earthquakes. Earthquakes are the result of plate tectonics, or shifting plates in the crust of Earth, and quakes occur when the frictional stress of gliding plate boundaries builds and causes ...


Earthquake: Earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another. Learn more about the causes and effects of earthquakes in this article.


Earthquakes happen when two large pieces of the Earth's crust suddenly slip. This causes shock waves to shake the surface of the Earth in the form of an earthquake.


Earthquake prediction is a branch of the science of seismology concerned with the specification of the time, location, and magnitude of future earthquakes within stated limits. Many methods have been developed for predicting the time and place in which earthquakes will occur.


The Science of Earthquakes The Science of Earthquakes. We usually only learn about the magnitude of an earthquake and the location of the epicenter. This infographic explains how ground waves and ...


An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. Current instrumentation shows that around 500,000 total earthquakes occur each year. Of those, around 100,000 are large enough to be felt by people.

Someday, researchers hope to find a way to predict earthquakes in advance, and perhaps even control them. In this article, we'll give you the latest scientific knowledge about earthquakes, and discuss how humans can cope with them. But first, here are some basic earthquake facts.
