A phase change in post-perovskite materials at the so-called D” discontinuity is also evidence for long-predicted slow, ...

Earthquakes, volcanic eruptions, shifting tectonic plates—these are all signs that our planet is alive. But what is revealed deep inside Earth surprises laymen and scientists alike: Almost 3000 ...

A New Frontier for Exoplanet Seismology While the JWST cannot directly detect seismic waves, it can measure variations in brightness—or photometric changes—with extraordinary precision.

A seismic wave recorded 15 minutes before the massive 2022 Tonga eruption could help scientists improve early-warning systems for remote oceanic volcanoes and mitigate tsunami risks.

The SEIS instrument, which contains the seismometer, uses the seismic waves naturally generated on Mars from Marsquakes or meteorite impacts to scan the planet's interior (Fig. 1).

Scientists have known that seismic waves slow down when passing through ultra-low velocity zones, or ULVZs, but only knew they existed around hotspots that create volcanic island chains. Now, a ...

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.

Geoscientists at ETH Zurich have solved a previously unexplained mystery using special laboratory experiments and computer simulations. They have demonstrated why earthquake waves change abruptly at a ...
