Earthquakes are broken down into two basic wave types: body waves (often called P-waves or S-waves which travel through the Earth) and surface waves (which travel along the Earth’s surface).

The strength and type of the seismic waves during an earthquake establish the severity of damage a region will sustain during the quake. ... There are two types of body waves. P, ...

Their goal is to build a catalogue of earthquake zones, showing which faults can generate the strongest and most dangerous types of seismic waves. The research was funded by the U.S. Geological ...

Ultrasounds and seismic waves are both types of sound waves, and they need a medium like air, liquid or rock to travel through. Because of that, when they come to a boundary between two substances ...

Earthquakes, more so than many other types of geologic or environmental disasters, defy prediction and prevention. Hurricanes can be identified many days before they arrive, giving coastal ...

A worldwide Android smartphone-based earthquake detection and early warning system can detect seismic activity in real time.

"The earthquake waves — seismic waves — can actually travel much further" on the East Coast, ... The types of earthquakes that occur on the East and West coasts are also different.

Supershear earthquakes occur when a fault ruptures faster than seismic shear waves can travel through rock. The events were thought to be rare because scientists had mostly looked for them on land.
