This fact sheet provides an overview of the basic components of a seismometer and physical science principles behind its operation.
- Seismometer: What is it and what does it measure? - Sensor TipsA seismometer is an instrument used to measure seismic (ground motion) activity caused by earthquakes, volcanic eruptions, the use of explosives or other forces.
- Seismographs - Keeping Track of Earthquakes | U.S. Geological SurveySeismic 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 detectors are connected to a system that produces a permanent recording, they are called seismographs.
- Seismometers | SAGE - IRISWhat is a seismometer? A seismometer is a very sensitive instrument that can detect movements of the Earth's surface. The surface is in constant motion due to natural and man-made phenomena. For example, the solid Earth tide is the stretching of the Earth due to the gravitational pull of the moon.
- Seismometers, seismographs, seismograms - what's 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.
