How much bigger is a magnitude... larger …An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two …A swarm, on the... "Foreshock" and "aftershock" are relative terms. Foreshocks are earthquakes that precede larger earthquakes in the same location. An earthquake cannot be identified as a foreshock until after a larger earthquake in the same area occurs. Aftershocks are smaller earthquakes that occur in the same general area during the days to ...

The magnitude, or size, of an earthquake is related to the total amount of energy released by the earthquake source. So a given earthquake has only one magnitude, but will produce different intensities of ground shaking at different locations. In this animation we use a light bulb to describe the difference between magnitude and intensity.

8. Almost all earthquakes occur in very narrow bands along oceanic ridges and transform faults, along continental transcurrent faults, or in broader zones below and behind island arcs. The depth distribution of earthquakes is also very limited.

Earthquakes can be measured in two ways. One method is based on magnitude—the amount of energy released at the earthquake source. The other is based on intensity—how much the ground shakes at a specific location.

In this activity, students explore the relationship between an earthquake's magnitude and intensity. Students calculate the energy released during a weight drop (magnitude) and use an accelerometer (iPhone, QCN, or other) to investigate what happens to this energy as the source is moved further and further from the sensor (intensity).

The moment magnitude scale is based on the total moment release of the earthquake. Moment is a product of the distance a fault moved and the force required to move it. It is derived from modeling recordings of the earthquake at multiple stations. Moment magnitude estimates are about the same as Richter magnitudes for small to large earthquakes.
