A seismometer is a device designed to measure movement in the Earth. Seismometers are typically used to measure seismic waves originating from an earthquake or explosion, and traveling through the ground as waves of force in the rocks and soil. The basic design of seismometers is typically based on two objects, or masses.Measuring Earthquakes. The vibrations produced by earthquakes are detected, recorded, and measured by instruments call seismographs. The zig-zag line made by a seismograph, called a "seismogram," reflects the changing intensity of the vibrations by responding to the motion of the ground surface beneath the instrument. The Modified Mercalli Intensity value assigned to a specific site after an earthquake has a more meaningful measure of severity to the nonscientist than the magnitude because intensity refers to the effects actually experienced at that place.v. t. e. The Richter scale [1] ( / ˈrɪktər / ), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale".
