Along the remote coast where the San Andreas Fault meets the Cascadia subduction zone, earthquakes too small for humans to ...

Seismic tremors reveal a shallow fragment of ancient tectonic plate beneath Northern California, helping explain damaging ...

The San Andreas Fault (red lines) and the other plate boundaries (green lines). Color contours indicate the presumed fault slip distribution of the 1700 Cascadia Subduction Zone earthquake. Circles ...

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

Evidence that a complete stress release may have contributed to the 2011 Tohoku earthquake that broke records. Both sedimentary formations above and below the plate boundary fault lie in the stress ...

• Due to a lack of data, the studies available so far underestimated the seismic and tsunami risk of these large faults. A new study led by the Institut de Ciències del Mar (ICM-CSIC) in Barcelona and ...

Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy.

The Pacific and Australian plates collide and interact in complex ways around New Zealand. Electrical resistivity data reveal that subduction-zone fluids exert an important influence on deformation in ...

Scientists discover ultra-weak faults near the 7.2 magnitude earthquake in Haiti that continued to slip for weeks.

Scientists have transformed the UNICORN computing code into an AI-like algorithm to more quickly simulate tectonic plate deformation due to a phenomenon called a ''fault slip,'' a sudden shift that ...
