Earthquakes are measured using the Richter scale, which assigns a magnitude value to indicate the strength of the earthquake. The units of magnitude used to measure earthquakes are logarithmic and are represented by whole numbers, such as 1, 2, 3, and so on.
seismograph is generally used to measure earthquakes.
The standard units used to measure the magnitude of earthquakes are the Richter scale and the moment magnitude scale.
