Seismograph?
The answer is: Richter scale or Richter scale.
A seismograph is a device that detects and records seismic waves when a mass moves. It consists of two axes, the horizontal axis measures time in seconds, and the vertical axis measures displacement. Developed by Charles Francis Richter in 1935, the Richter scale is a numerical scale used to measure the intensity of earthquakes. Using a seismograph or seismometer, scientists and researchers can detect and record earthquake vibrations and vibrations, making them useful for detection and surveying. This device has been an invaluable tool for understanding seismic events, providing researchers with detailed information about their size and location.
