Seismometer: measure moions of the ground watch how a seismograph works" on youtube. Principle of the seismograph: the ineria of the mass tends to keep it moionless. While the recording drum,which is anchored provides a reference point from which to measure the amount of displacement occurring as the seismic wave passes through the ground. This draws the squiggly line on the rotaing drum shown on the right. Seismometer can detect energy from an earthquake, but how do we actually ind the focus of an. We irst need to know what seismic waves are, and how they behave. Body waves" - energy (waves) that are radiated in all direcions from the focus.
