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 ...

In a groundbreaking studypublished in Seismological Research Letters, Australian National University (ANU) scientists have found that powerful winter storms in the North Atlantic Ocean send seismic ...

Strange seismic waves that rippled around world leave scientists bewildered 'I don't think I've seen anything like it,' seismologist says. Harry Cockburn. Thursday 29 November 2018 16:58 GMT.

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 ...

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 ...

Seismologists may have determined the origin of a strange type of seismic wave. Michael Thorne, University of Utah. PKP waves are a subset of P-waves (primary waves), which are compressional ...

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 ...

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.

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 ...
