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 measuring and …

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 these …

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

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 phenomena, …

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 motions in the earth's …

Jun 20, 2025 · Seismographs record a zigzag trace that shows the varying amplitude of ground oscillations beneath the instrument. Sensitive seismographs, which greatly magnify these ground …

May 28, 2024 · At its core, a seismograph is an instrument comprising essentially two parts: a mass that remains relatively stationary when the Earth shakes, and a recording device connected to a base …

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 is called a …

These seismogram displays depict ground motion recorded by seismograph stations in real-time, updated every few minutes. Each plot represents 24 hours of data from one station.
