Subduction zones arise where one tectonic plate descends beneath another, driving a suite of processes that shape Earth’s surface and generate significant seismic hazards. At these convergent margins, ...

Groundbreaking research has provided new insight into the tectonic plate shifts that create some of the Earth's largest earthquakes and tsunamis. Groundbreaking research has provided new insight into ...

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 ...

When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth's surface. The magma escapes through weaknesses in the rock and rises up through a ...

Evaluation of landforms, soils, and deposits formed by active tectonics is providing basic data necessary for long-term earthquake prediction, seismic-hazard evaluation, and probabilistic seismic-risk ...

Jessica DePaolis (second from left) and the team of researchers studied and compared sedimentary core samples in Montague Island, Alaska, and found evidence that four of the past eight earthquakes ...

Volcanic eruptions frequently interfere with human affairs; impacts range from minor nuisances to major disasters. Some 50 to 65 different volcanoes typically are active in any given year, and among ...
