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 ...

• 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 ...

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 ...

(Phys.org)—A team of researchers with members from several institutions in Singapore, France and Indonesia has found evidence of a possible new plate boundary forming on the floor of the Indian Ocean ...

A hidden shard of ancient crust has been detected where California’s San Andreas system collides with the Cascadia subduction zone, reshaping how I understand the tectonic engine of the West Coast.

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 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 ...

Earthquakes, large and small, happen every single day along zones that wrap around the world like seams on a baseball. Most don't bother anybody, so they don't make the news. But every now and then a ...

September 2017 saw a pair of weird earthquakes in Mexico. A magnitude 8.2 on September 8 just offshore the state of Chiapas was followed by a magnitude 7.1 on September 19—this time much closer to ...

A new study led by the Institut de Ciències del Mar (ICM-CSIC) in Barcelona and the Institució Catalana de Recerca i Estudis Avançats (ICREA) has revealed the exact location of the boundary between ...
