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 ...

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

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 ...

Scientists from Utrecht University have discovered two enormous structures deep in Earth's mantle, suggesting that these regions are significantly older and hotter than surrounding tectonic plates.

Seismic waves were seen to slow down drastically in these areas, which earned them the awkward scientific name of Large Low ...

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." ...
