The geological events we see on the surface of the Earth as mountains, volcanoes and earthquakes are expressions of processes that are happening deep in our planet. Here on the Earth's crust, we're part of a conveyor belt ...

Subduction zones, where a slab of oceanic plate is pushed beneath another tectonic plate down into the mantle, cause the world's largest and most destructive earthquakes. Reconstructing the geometry and stress conditions ...

In modern subduction zones—regions around the world that have one tectonic plate sliding past another—one area can act like molasses for seismic waves. These anomalous areas are called low-velocity zones, or LVZs. In ...

Earthquakes—like lightning—strike unpredictably. The Earth's tectonic plates, however, hide subtle warnings that a major fault may soon break. Like forecasting a thunderstorm, knowing how to read the warnings could help ...

Slow earthquakes are long-period earthquakes that are not so dangerous alone, but are able to trigger more destructive earthquakes. Their origins lie in tectonic plate boundaries where one plate subsides below another. Though ...

Subduction zones are cornerstone components of plate tectonics, with one plate sliding beneath another back into Earth's mantle. But the very beginning of this process—subduction initiation—remains somewhat mysterious ...
