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 mysterious earthquake waves suggest that these features might be widespread. ULVZs, which are located in the lower mantle near the core-mantle boundary, can slow seismic waves by up to 50%.

A magnitude 3.8 earthquake was recorded at 10:22 a.m. on Monday and was about 10 kilometers southeast of York Harbor, ...

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 ...

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 ...
