WebJan 25, 2024 · An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves. Note: The above text is excerpted from the Wikipedia article "Earthquake", which ... WebSeismic waves travel outward in all directions from a point call the focus of an earthquake. The focus is usually far below the Earth, in which case it is useful for geologist to determine the epicenter, the point on the Earth’s surface that is directly above the focus. This is the area that can experience the most Figure 2. Location of the ...

The place right above the focus (at the ground surface) is called the epicenter of the earthquake. Cutaway view of the reverse fault. The earthquake starts at the focus, with slip continuing along the fault.
WebEarthquakes develop in the crust part of the earth. The crust involves the earth’s surface, submarine levels, and down to the ocean floors. The inner part of the earth contains massive energy. Some of this energy escapes through cracks and other volcanic activity, but the bulk of it is stored within the earth’s inner part, contained in the ... WebAn earthquake is happening.
