Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

Seismic readings of the interior of Mars strongly suggest large quantities of water buried 6 to 12 miles underground.

"We combined the measured seismic wave speed, gravity measurements and rock physics models. The rock physics models are the same as the ones we use to measure properties of aquifers on Earth or ...

The questions in this quiz are suitable for GCSE physics students who are studying sound waves, ultrasound and seismic waves. If you struggled with the quiz, don't panic - we've got you!

Research in the last decade has concentrated on developing methods to focus seismic models derived from surface wave dispersion information to tectonic scales, particularly in the US and China. Recent ...

which uses "electrical energy . . . as a wave source" that "monitor[s] seismic wave energy" on dry, wet, and frozen diabase samples. Experimentation revealed that the seismic velocities of the dry ...

Seismologists have long known that seismic waves—generated by earthquakes—do not travel through all parts of Earth's interior at the same speed. This principle has allowed them to visualize ...

Scientists have long known that there are LLVPs — one below the Pacific Ocean and the other below Africa. In these regions, seismic waves from earthquakes travel 1% to 3% more slowly than they ...

Seismic waves passing through these soft sediments grow stronger in amplitude, leading to stronger shaking that is more likely to damage infrastructure. Singapore lies a few hundred kilometers ...
