While earthquake locations are normally done with a computer that can quickly determine the paths of seismic waves through the Earth to many seismic stations, you can get a good estimate of an ...

There are a number of ways to measure the magnitude of an earthquake. Most scales are based on the amplitude of seismic waves recorded on seismometers. These scales account for the distance between ...

But beneath that simple diagram lies a way more complicated and mysterious story—one that scientists are only now beginning to understand. Using seismic waves from earthquakes as a kind of X-ray ...

The S wave shadow zone ... detected following an earthquake. This shadow zone has led geologists to a model of the Earth with a solid mantle and a liquid core. From the diagram, we can see the ...

These plates move slowly, but can cause earthquakes and volcanoes where they meet. The seismic waves produced by an earthquake are monitored and tracked. The Earth is almost a sphere. These are ...
