When an earthquake hits, it is rarely an isolated event. Foreshocks precede quakes, and aftershocks follow them. To quantify seismic hazards, scientists must disentangle the factors that contribute to these shaking sequences.

When two rocks interact with each other in a fault zone, the roughness of their surfaces could influence the outcome, including when they cause earthquakes. Still, the underlying mechanics of this relationship remain unclear.

Earthquakes in the Nenana Basin region of Interior Alaska last longer and feel much stronger than a quake of comparable magnitude would in a non-basin region, due to the behavior of the seismic waves once they reach the area.

A trio of researchers from James Cook University, working with a colleague from the University of Adelaide, has found metamorphic diamonds in rocks near Australia's northeast coast. In their paper published in the journal ...
Strike-slip faults can be fickle about their movement—they can move slow and steady or remain stationary until their built-up stress is let loose in one go. But how do these faults' movements change from a locked and sudden ...
