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 ...

While we detected seismic waves on the moon while the Apollo seismometer network was active, this is the first time we've detected seismic surface waves on any body other than Earth before.

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.

Why seismic waves spontaneously race inside the Earth. Story by Peter Rüegg • 1w. E arthquakes, volcanic eruptions, shifting tectonic plates—these are all signs that our planet is alive.

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 ...

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 ...

Two types of seismic signals. Ocean waves generate microseismic signals in two different ways.. The most energetic of the two, known as the secondary microseism, throbs at a period between about ...

Seismic waves inside Mars' core hint at how it became hostile to life : Read more The article gets the Earth's solid inner and liquid outer core backwards.

Samuel’s team went beyond considerations of density, composition, and seismic velocity and looked at how the interior structure of Mars attenuated seismic waves. “From this, we were able to infer the ...

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 ...

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 ...

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 ...
