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.

As their names suggest, ULVZs slow down seismic waves, and scientists have known about these strange areas that tend to hang around hotspots, which are regions where mantle wells up through the ...

Waves from these quakes traveled through the core and up to North America, where they were recorded by EarthScope, a project that deployed portable seismic monitors across the U.S. between 2003 ...

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth’s inner core, according to seismologists from The Australian National University (ANU).

Probably the most important data we can collect about Earth's interior is how quickly seismic waves generated by earthquakes pass through the planet. Depending on the layers they intersect, the waves ...

Scientists recorded a seismic event so strange that they named it a USO—unidentified seismic object. It reverberated around the world for a staggering 9 days.

Seismic Waves tell lithospheric delamination mechanism in south China. University of Science and Technology of China. Journal Nature Communications DOI 10.1038/s41467-023-37855-5. Keywords ...

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 ...

It turns out that the interior of Mars exhibits seismic waves just like the Earth, according to a new study published in the Proceedings of the National Academy of Sciences. Using seismic data ...
