Prof. . Militzer. Background/Method. As seismic waves travel through different mediums in the earth, the different mediums create different wave velocities. With geophones, the amplitude of the wave response can be measured at the surface and overlaid to create travel-time curves that tell what’s underneath..

A short lecture activity sequence designed to engage students in learning about EQ epicenter location . 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.. earthquake.
