A new kind of earthquake has been detected in western Canada, one that shakes the ground slower and longer than typical ...

Most of what is known about what lies beneath comes from seismic waves — the vibrations of earthquakes traveling through and around the planet. Think of them as a giant sonogram of Earth.

The messages claimed that the "Seismic Waves Card" file was being displayed as photos of the earthquake. "This is false," a WhatsApp spokesperson told us via email at the time.

The wave pattern seen on 11 November resembled these slow-moving waveforms usually seen following large earthquakes - only, in this case, there had not been a perceptible earthquake.

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%.

Each year, National Earthquake Information Center locates approximately 20,000 earthquakes around the world. That is about 55 earthquakes per day. By some estimates, there may be even more ...

Strange waves rippled around the world, and nobody knows why. Instruments picked up the seismic waves more than 10,000 miles away—but bizarrely, nobody felt them.

An earthquake is primarily measured by an instrument called a ‘seismograph’, which produces a digital graphic recording of the ground motion caused by seismic waves, called a ‘seismogram’.

People close to the epicenter of an earthquake typically feel the more intense P waves, even though the S waves come right after them, according to the U.S. Geological Survey.

Researchers have developed a new hybrid earthquake early warning system called HEWFERS, which leverages advanced machine ...

These mysterious waves, known as PKP precursors, arrive just before a type of seismic wave known as PKP waves, which travel through the Earth during an earthquake.
