WebJun 15, 2024 · A seismometer is an instrument used to measure seismic (ground motion) activity caused by earthquakes, volcanic eruptions, the use of explosives or other forces. … WebBasic Principles. Inertial seismometers have levers in them that keep rhythmic motion. A weight, usually called the internal mass, that can move relative to the instrument frame, but is attached to it by a system (such as a spring) that will hold it fixed relative to the frame if there is no motion, and also damp out any motions once the motion ...

WebApr 12, 2024 · Large earthquakes can produce ground shaking that is strong enough to damage buildings and topple geologic features. One important and unresolved problem in earthquake hazard analysis is knowing how strong ground motions are likely to be at distances very close to the fault surface.
