A recent study has mathematically clarified how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. The researchers derived a new equation that ...

Seismic waves can be generated also by the impact of objects on the ground. The analysis of seismic waves provided insights on what happened September 11, ... There are no P- or S-Waves, ...

Researchers have mathematically elucidated how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. A novel equation was derived to describe the travel of ...

If you're in an earthquake-prone area and own an Android phone, it could save your life. It may even have already done so.

Unlike the direct and strong P- and S-seismic waves produced by an earthquake or explosion event, coda waves arrive later and are more sensitive to scattering by the rock that they pass through.

The first studies of the 28 March 2025 magnitude 7.8 Myanmar earthquake suggest that the southern portion of its rupture ...

Two Australian scientists argue in a new paper that within the Earth’s core, based on measurements of waves reverberating along the Earth’s diameter, is an innermost inner core, about 800 ...

A Revolutionary Way to Study Earth’s Core. Seismic waves, traditionally generated by earthquakes, can now be detected from the movement of ocean waters caused by intense storms.

The P-wave (P for “primary” because it’s the first to arrive) is analogous to a sound wave, as it compresses the rock in the same direction it’s traveling.

For 20 minutes on Nov. 11, 2018, strange seismic waves reverberated around the Earth for nearly 11,000 miles — and we have no idea what they were. No one felt them; nothing was destroyed by them ...

Unlike the direct and strong P- and S-seismic waves produced by an earthquake or explosion event, coda waves arrive later and are more sensitive to scattering by the rock that they pass through.
