=== Strong-motion seismometers ===
Another type of seismometer is a digital strong-motion seismometer, or [[accelerograph]]. The data from such an instrument is essential to understand how an earthquake affects man-made structures, through [[earthquake engineering]]. The recordings of such instruments are crucial for the assessment of [[seismic hazard]], through [[Engineering Seismology|engineering seismology]].

A strong-motion seismometer measures acceleration. This can be mathematically [[Integral|integrated]] later to give velocity and position. Strong-motion seismometers are not as sensitive to ground motions as teleseismic instruments but they stay on scale during the strongest seismic shaking.

Strong motion sensors are used for intensity meter applications.
