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 ...

Slow slip earthquakes, a type of slow motion tremor, have been detected at many of the world's earthquake hotspots, including those found around the Pacific Ring of Fire, but it is unclear how they are connected to the damaging ...

When two of Earth's tectonic plates collide, the heavier plate is forced underneath and back into the mantle in a process called subduction. During the early stages of newly initiated subduction zones, the uppermost part ...
