Seismograph, instrument that makes a record of seismic waves caused by earthquakes and other Earth-shaking phenomena.

Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic …

A seismograph is a device for measuring the movement of the earth, and consists of a ground-motion detection sensor, called a seismometer, coupled with a recording system.

What is a seismograph and how does it work? A seismograph is an instrument which uses a seismometer to detect, measure and record ground movements caused by seismic …

Aug 30, 2023 · Have you ever wondered how scientists record local earthquakes without the equipment shaking? A seismograph is an instrument that can detect and record ground …

Seismograph and seismometer are both instruments used to measure seismic activity, but they serve slightly different purposes. A seismograph is a device that records the motion of the …

Jun 13, 2025 · A seismograph is a sensitive instrument that measures the ground motion caused by seismic waves. It consists of a sensor, known as a seismometer, which detects the ground …

Jun 20, 2025 · A seismograph is the device that scientists use to measure earthquakes. The goal of a seismograph is to record the motion of the ground during a quake accurately.

A seismograph is an instrument that measures and records the motion of the ground caused by earthquakes, volcanic eruptions, and other seismic events. It consists of a sensor, called a …

Seismic waves lose much of their energy in traveling over great distances. But sensitive detectors (seismometers) can record theses waves emitted by even the smallest earthquakes. When …
