Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

Now, researchers have connected 49 seismic events to impact craters, proving that meteorite strikes leave distinct seismic ...

To find out, the team used whole-Earth oscillation data from 104 past earthquakes to create a detailed 3D model of the upper ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds.

Miller at Australian National University, concluded that the unusually long seismic wave could have been due to a "low-velocity layer at the base of the subducting Alboran slab." Seismic waves are ...

Because seismic waves pass more slowly through these objects, they are called “large low-shear-velocity provinces”, or LLSVPs. But not much else about their composition or origin is known.

Low-velocity layers, through which seismic waves are slowed and absorbed, often indicate that the waves have passed through melted or liquid material. Subducted slabs usually contain a low ...

And we see that seismic waves slow down there." Earth scientists therefore call these regions "Large Low Seismic Velocity Provinces" or LLSVPs. "The waves slow down because the LLSVPs are hot ...

Known as large low-seismic-velocity provinces (LLSVPs), these blobs ... "The only thing that we know of these is that when seismic waves travel through these places, they slow down." ...
