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

Seismograph is another Greek term from seismós and γράφω, gráphō, to draw. It is often used to mean seismometer, though it is more applicable to the older instruments in which the …

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 …

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.

A seismometer is an extremely sensitive electromechanical device used to measure ground movement in a particular area in the order of nanometres (millionths of a millimetre). The …

Seismograph A seismograph is an instrument used to measure seismic waves. Seismic waves are energy that passes through Earth's crust, or top layer. Seismic waves occur for many …

During an earthquake, vibrations caused by the breakage of rock along a fault zone radiate outward from the point of rupture. The instrument used to record and measure these vibrations …

A seismograph is a scientific instrument used to detect and record seismic waves, which are the vibrations caused by earthquakes, volcanic eruptions, or large explosions.

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 …

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.
