Tsunami model amplitude information is shown colour-coded to the scale. Filled colours show maximum computed tsunami amplitude in cm during 24 hours of wave propagation. Black contours show computed tsunami arrival time. . Seismograph. Or seismometer, is an instrument used to detect and record earthquakes.. Seismogram. A record written by a seismograph in response to ground motions produced by an earthquake, explosion, or other ground-motion sources.. Tectonic plates are huge rock pieces within the earth’s crust. The plates are usually marked by fractures or fault lines formed when the plates tear apart or slide or collide past each other. This results in a change of the earth’s interior masses which send out powerful shock waves with enough force to alter the surface of the earth. The shock waves can thrust up cliffs and open huge cracks on the ground leading to an earthquake event. Earthquake Risk. Earthquakes are likely wherever plate movement stores energy in the rock along faults.. Geologists can determine earthquake risk by locating where faults are active and where past earthquakes have occurred.. Alan Kafka, Boston College. Michael Hubenthal, IRIS. Did you feel it?.
