Answer:
The epicenter is the map location on Earth's surface, above where earthquake began. An earthquake actually begins inside the earth at the hypocenter.Volcanoes and earthquakes are not randomly distributed around the globe. Instead they tend to occur along limited zones or belts. With the understanding of plate tectonics, scientists recognized that these belts occur along plate boundaries.Three Types of Waves
Major earthquakes occur when there is rock movement along a fault (crack in the crust). The sudden slippage of huge rock masses sets up shock waves that travel through the earth. The point within the earth where the actual movement takes place is called the focus. As shown in Figure 1, the point on the surface directly above the focus is called the epicenter.
An earthquake epicenter can be located from records made of earthquake waves on devices called seismographs. One type of seismograph is a visible recording machine, shown in Figure 2. A pen draws a pattern of the waves on paper that is attached to a revolving drum. The wave record from a seismograph is known as a Three Types of Waves
