What tool is used to record earthquake waves?
Question Date: 2007-09-23
Answer 1:

This is called a seismograph. The basic idea is to record the ground motions in terms of displacement, velocity and accelerations at a fixed location during the event. Ground motion is caused by the propagation of seismic (elastic waves) due to rupture or failure of rocks, due to the local stresses exceeding the brittle of rock strength.
