Its murmurs tend not to be signs of volcanic unrest but rather the signature of avalanches large enough to register on nearby ...

In 2023, a strange seismic signal was detected every 90 seconds for nine days. Researchers identified tsunami waves trapped ...

Seismic waves accelerate in the D" layer, about 2,700 km deep, due to the alignment of post-perovskite crystals, which occurs as solid mantle rock flows horizontally under extreme pressure and ...

Researchers have unveiled the first direct evidence of these massive waves and linked them to bizarre seismic signals that ...

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 ...

They have demonstrated why earthquake waves change abruptly at a depth of 2,700 kilometres at the so-called D‘’ layer. The reason for this is a type of solid rock that nevertheless flows. This mineral ...

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades. Close. Advertisement. Skip to content.

A seismograph in Norman, Oklahoma, recorded the seismic surface wave generated by a 7.0 magnitude earthquake off the northern coast of California on December 5, 2024. SAGE ...

On September 16, 2023, several seismic stations worldwide detected a bizarre signal. Earthquakes are not rare. In 2023 alone, 1,712 earthquakes of magnitude 5 or more were registered worldwide.

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 ...

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 ...

They analyzed changes in the velocity of seismic waves traveling through the LA basin, tracking these changes in space and time between January and October 2023. Advanced Search.
