In September 2023, a global seismic mystery began to unfold. Every 90 seconds, the Earth pulsed with a strange, low-frequency ...

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

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.

There are actually many types of seismic core phases that traverse a specific ray path. For example, PcP waves begin as a primary wave (P-wave) and deflect at the CMB and return as a P-wave.

Seismic waves suggest that Earth has a hidden heart, a distinct region within the solid part of the planet’s core.

SEIS was the first ever seismometer to operate on Mars, and it was sensitive to three different types of seismic wave emanating from marsquakes.

Over a thousand miles from the surface, in Earth’s D” layer—right on the edge of the liquid metal outer core—there is a weird acceleration of seismic waves. Experiments recreating the ...

Seismic data would likely be integrated with many types of measurements to produce the comprehensive picture of groundwater dynamics needed to manage the valuable resource in a data-informed and ...

By tracking seismic waves from earthquakes that have passed through the Earth’s inner core along similar paths since 1964, the authors of the 2023 study found that the spin followed a 70-year cycle.

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 ...

Measuring the wiggles in this laser light gives researchers information about the passing wave, making the 10-kilometer cable equivalent to a line of thousands of conventional seismic sensors.
