(a) Geological units and earthquake distribution of an oceanic subduction zone. The orange shadow beneath the volcanic arc represents partially molten areas and magma channels. (b) Thermal structure ...

One of the most terrifying discoveries for the US population in general has just been made off the north coast of California. Scientists have found geological faults that had remai ...

Geophysicists can use a new model to explain the behavior of a tectonic plate sinking into a subduction zone in the Earth's mantle: the plate becomes weak and thus more deformable when mineral grains ...

Subduction zones, where one tectonic plate slides beneath another, produce the most devastating seismic, volcanic, and landslide hazards on the planet. A new report presents an ambitious plan to make ...

An unprecedented observation of a major geological process is currently taking place off the North American coast. For the first time, a scientific team has documented the progressive fragmentation of ...

A hidden chunk of an ancient tectonic plate is stuck to the Pacific Ocean floor and sliding under North America, complicating earthquake risk at the Cascadia subduction zone.

Among seismologists, the geology of Alaska's earthquake- and volcano-rich coast from the Aleutian Islands to the southeast is fascinating, but not well understood. Now, with more sophisticated tools ...

Northern California’s coast keeps you on alert, even on quiet days. Offshore, three tectonic plates meet near Humboldt County ...

Tremors beneath Northern California show hidden plate movement, helping scientists better understand where future big ...
