Earthquake

Crystal to point an early start for the active global process that shapes Earth's surface and climate

How do these subduction zones originate, and how do they evolve over time?

Simulation approach works for a large mountain.

Earthquake depth impacts potential tsunami threat.

They are slower and last longer.

The results point to a cool, more sluggish early mantle.

The quakes add weight to the idea that the location is a center of seismic activity.

Scientists reviewed current knowledge, and introduce a novel framework to help characterize earthquake-triggering processes.

The answer lies in the consideration of major heat-loss mechanisms

Oceanic lithosphere carries volatiles, notably water, into the mantle through subduction at convergent plate boundaries. This subducted water exercises control on the production of...

Most of what we know about the interior of the Earth comes from the study of seismic waves from earthquakes. These waves contain vital...

Temporal changes of inner-core (IC) seismic phases have been confirmed with high-quality waveform doublets. However, the nature of the temporal changes is still controversial. Geologists...
