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

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 ...

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 ...

Falcon 9 sonic booms can feel more like seismic waves Trajectories, wind shear, temperature gradients, topography, and weather can affect how a sonic boom spreads.

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 ...

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 ...

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

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other ...

About 2,890 kilometres beneath our feet lies a gigantic ball of liquid metal: our planet’s core. Scientists like me use the seismic waves created by earthquakes as a kind of ultrasound to “see ...

This seismic scattering has long puzzled scientists, but a new study pinpoints where more of these mysterious areas may be hiding.

A previously unknown doughnut-shaped region found inside Earth’s core deepens understanding of planet’s magnetic field ...

Structures that scatter seismic waves deep in Earth's mantle seem to be everywhere researchers look.
