The S wave shadow zone is the area of the Earth’s surface where S waves are not detected following an earthquake. This shadow zone has led geologists to a model of the Earth with a solid mantle ...

There are different kinds of earthquake waves: body waves and surface waves. Body waves pass through the interior of the Earth whereas surface waves travel along the Earth's surface. Explain that ...

A recording of an earthquake has recognizable characteristics. Typically, one can recognize the arrival of different wave types. The P waves (the fastest traveling waves), S waves, and Surface waves ...

A seismometer is an instrument that records the shaking of the Earth's surface caused by seismic waves. The term seismograph usually refers to the combined seismometer and recording device. The first ...

To figure out just where that earthquake happened, you need recordings from seismic stations in other places. While earthquake locations are normally done with a computer that can quickly determine ...

Researchers examining seismic data recorded on Mars say the have found evidence supporting the presence of liquid water deep ...

S waves do not pass through the Earth's core ... It is the slowest of the three types of seismic wave. Surface waves usually have larger amplitude than the other waves and cause the most damage.
