Seismic waves from earthquakes have always offered a window into Earth’s hidden interior. For decades, researchers believed ...

This early rocky shell featured chemical signatures previously thought to occur only in continental crusts made by the ...

The tiny Juan de Fuca plate is largely responsible for the volcanoes ... The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another ...

Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones. As these older sections of plates sink, newer and less dense sections of plate are pulled along behind.

Tectonics is the study of the structural geology ... the Lesser Antilles subduction zone act as a strong asperity on the plate interface and release fluids that drive hydrofracturing and ...

Its study includes plate tectonics, volcanism, the chemistry of lava and volcanic rocks, gravity and geomagnetic anomalies as well as seismic investigations into the structure of the mantle.
