Broadband Seismometer

Broadband seismometers can detect motion over a wide range (or band) of frequencies and usually over a large range of amplitudes (the dynamic range). Broadband sensors respond to most frequencies from 0.01 Hz to 50 Hz. For regional seismology, the frequency range of interest is from 0.05 to 20 Hz therefore; broadband sensors are most useful for recording regional earthquakes and teleseismic events.
