He pointed out that seismograph records of the earthmovements due to distant earthquakes proves that an earthquake is the source of two types of wave motion which pass through the body of the ...

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).

Scientists say a warning system could have given people on the Alaska Peninsula 10 seconds or more to brace themselves for July's M7.3 earthquake.

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).

Seismic sound waves crossing the deep ocean could be a new thermometer Sumatran earthquakes can be used to track the warming of the Indian Ocean.

Using a novel device that simulates earthquakes in a laboratory setting, scientists have shown that seismic waves -- the sounds radiated from earthquakes -- can induce earthquake aftershocks ...

A new kind of earthquake has been detected in western Canada, one that shakes the ground slower and longer than typical seismic events. These earthquakes, recorded during hydraulic fracturing for ...

A rare type of deep-Earth tremor called an S wave generated by a rapidly strengthening storm could help scientists map the planet’s mantle and core.

An 8.8-magnitude earthquake struck off Russia’s eastern coast on late Wednesday morning, local time. The quake triggered ...
