Detailed explanation-1: -Seismometers allow us to detect and measure earthquakes by converting vibrations due to seismic waves into electrical signals, which we can then display as seismograms on a computer screen. Seismologists study earthquakes and can use this data to determine where and how big a particular earthquake is.

Detailed explanation-2: -A seismometer, or seismograph, is a device that geologists use to measure and record seismic waves. By studying these recordings, scientists can map the earth’s interior, and they can measure or locate earthquakes and other ground motions.

Detailed explanation-3: -This article was reviewed by a member of Caltech’s Faculty. It is not currently possible to predict exactly when and where an earthquake will occur, nor how large it will be. However, seismologists can estimate where earthquakes may be likely to strike by calculating probabilities and forecasts.
