The Mercalli scale also measures the effects of an earthquake at different locations.Annual Earthquakes. In a single year, on average, more than 900,000 earthquakes are recorded and 150,000 of them are strong enough to be felt. Each year about 18 earthquakes are major with a Richter magnitude of 7.0 to 7.9, and on average one earthquake has a magnitude of 8 to 8.9. Magnitude 9 earthquakes are rare.One advantage of the moment magnitude scale over the Richter scale is that it can be used to measure earthquakes of any size, from the smallest to the largest.

Knowing how fast ...Earthquake detection. A seismogram is a record of the ground motions caused by seismic waves from an earthquake. A seismograph or seismometer is the measuring instrument that creates the seismogram. Almost all seismometers are based on the principle of inertia, that is, where a suspended mass tends to remain still when the ground moves. Although numerousintensity scales have been developed over the last several hundred years to evaluate the effects of earthquakes, the one currently used in the United States is the Modified Mercalli (MM) Intensity Scale. It was developed in 1931 by the American seismologists Harry Wood and Frank Neumann. Earthquakes are measured using instruments called seismometers, that detect the vibrations caused by seismic waves as they travel through the crust. Seismic waves can be both natural (from earthquakes) or caused by human activity (explosions). How is an earthquake's origin and intensity identified?

Seismographs - Keeping Track of Earthquakes. By Earthquake Hazards Program. Throw a rock into a pond or lake and watch the waves rippling out in all directions from the point of impact.
