  • Seismometer - Wikipedia
    A seismometer is an instrument that responds to ground displacement and shaking such as caused by quakes, volcanic eruptions, and explosions They are usually combined with a timing device and a recording device to form a seismograph [1]
  • Seismometers, seismographs, seismograms - whats the difference? How do . . .
    A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with "seismograph" Seismographs are instruments used to record the motion of the ground during an earthquake
  • How Does a Seismometer Work? - IRIS
    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 This fact sheet provides an overview of the basic components of a seismometer and physical science principles behind its operation
  • How a seismometer works - SEIS Mars InSight
    A seismometer is a device that is sensitive to vibrations It works on the principle of a pendulum: a heavy, inert mass with a certain resistance to movement (i e inertia) due to its weight is suspended from a frame by a spring that allows movement
  • How seismometers work step-by-step | Description, Example Application
    Learn how seismometers work step-by-step Discover the principle of operation, types of seismometers, and applications in seismology Seismometers are devices used to measure seismic waves, which are waves of energy that propagate through the Earth’s crust following an earthquake or other seismic event
  • Seismometer: What is it and what does it measure? - Sensor Tips
    A seismometer is an instrument used to measure seismic (ground motion) activity caused by earthquakes, volcanic eruptions, the use of explosives or other forces
  • What is a Seismometer? (with pictures) - AllTheScience
    A seismometer is a device designed to measure movement in the Earth Seismometers are typically used to measure seismic waves originating from an earthquake or explosion, and traveling through the ground as waves of force in the rocks and soil
  • Real-time Seismogram Displays - USGS Earthquake Hazards Program
    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 Read more »
  • Sensors | EarthScope Primary Instrument Center
    Seismometers are instruments that measure and record motions of the ground, including those of seismic waves generated by earthquakes, nuclear explosions, and other seismic sources Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources
  • Seismograph vs. Seismometer — What’s the Difference?
    Seismographs record earthquake data on paper, while seismometers measure ground motion digitally or mechanically A seismograph is a device that includes both a seismometer and a recording system; it produces a physical record of seismic waves on paper or film
