A measure of the strength of an earthquake.

Shallow earthquakes are between 0 and 70 km deep; intermediate earthquakes, 70 - 300 km deep; and deep earthquakes, 300 - 700 km deep. In general, the term "deep-focus earthquakes" is applied to earthquakes deeper than 70 km. All earthquakes deeper than 70 km are localized within great slabs of lithosphere that are sinking into the Earth's mantle.10. Each time the magnitude increases by one unit, the measured ground motion becomes 10 times larger. The Richter Scale. A measure of the degree to which an earthquake is felt by people and the amount of damage caused by the earthquake. intensity. Seismologists in the U.S. use this to measure earthquake intensity.Measures the total energy released by an earthquake. Moment magnitude is calculated from the area of the fault that is ruptured and the distance the ground moved along the fault. The Richter scale and the moment magnitude scale are logarithmic. The amplitude of the largest wave increases ten times from one integer to the next. Magnitude and intensity are different, yet related concepts. The size of an earthquake, or magnitude, is a single value, while seismic intensity, a measure of the strength of shaking at a specific location, varies depending on location. Three learning options provide hands-on activities to understand the differences between an earthquake’s magnitude and shaking intensity using different ...

A normal (dip-slip) fault is an inclined fracture where the rock mass above an inclined fault moves down (Public domain.) An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts ...Earthquake epicenters occur mostly along tectonic plate boundaries, and especially on the Pacific Ring of Fire. An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth 's lithosphere that creates seismic waves. v. t. e.
