Once the earthquake waves are far enough away from the location where the earthquake occurred, they can no longer be felt by people, BUT they can still be detected by sensitive seismic instruments. 1. 2. 10. EarthScope Consortium WebEarthquake detection. A seismogram is a record of the ground motions caused by seismic waves from an earthquake. A seismograph or seismometer is the measuring instrument that creates the seismogram. Almost all seismometers are based on the principle of inertia, that is, where a suspended mass tends to remain still when the ground moves.
