Seismograph, the Richter Scale and the Mercalli Scale are used for measuring the direction and intensity of earthquakes.No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. That is, the longer the fault, the larger the earthquake. A fault is a break in the rocks that make up the Earth's crust, along which rocks on either side have moved past each other. No fault long …

Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations. Each earthquake produces three basic types of seismic waves. Each seismic wave has a different type of motion and travels through the earth at different speeds. Scientists measure seismic waves produced by an earthquake using devices such as a seismograph (or seismometer). A seismograph records ground vibrations.
