What is used to measure the magnitude of an earthquake.
The time, location, and magnitude of an earthquake can be determined from the data recorded by seismometer. Seismometers record the vibrations from earthquakes that travel through the Earth. Each seismometer records the shaking of the ground directly beneath it.
The Richter scale is used to rate the magnitude of an earthquake — the amount of energy it released. This is calculated using information gathered by a seismograph. The Richter scale is logarithmic, meaning that whole-number jumps indicate a tenfold increase. In this case, the increase is in wave amplitude. That is, the wave …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". [3] The Mercalli scale is a seismic scale used to measure the intensity of an earthquake. The measurement is based on observations and experiences, and it is currently measured on a scale of 12 degrees of intensity, indicated by Roman numerals I through XII. The Mercalli scale differs from the Richter scale, which measures the magnitude of earthquakes.The time, location, and magnitude of an earthquake can be determined from the data recorded by seismometer. Seismometers record the vibrations from earthquakes that travel through the Earth.
