Seismometers. For information on how seismometers are used, please see the related question.
The success rate of a seismograph is typically high, as it is designed to accurately record seismic activity. However, the effectiveness of a seismograph can be influenced by factors such as maintenance, calibration, and installation location. Routine checks and maintenance can help ensure the reliability and accuracy of the data recorded by a seismograph.
a seismograph
An earthquake is measured using a machine called a seismograph. The magnitude of an earthquake was measured at one time using the Richter magnitude scale., but that has been superseded by the moment magnitude scale (MMS). Subjective impressions of the intensity of an earthquake is sometimes reported using a modified Mercalli scale.

A seismograph is the device that scientists use to measure earthquakes. The goal of a seismograph is to accurately record the motion of the ground during a quake
