New methods of machine learning are bringing the phase arrival time and polarity picking used for automatic determination of earthquake fault planes to accuracies better than human analysists.Read More »Geology & Geophysics
Scientists show small earthquakes caused by fracking near Guy-Greenbrier, Ark., in 2010 that could have been early indicators of high stress levels on larger faults deeper underground.Read More »
Last year, two major earthquakes—one 12 days after the first—shook Mexico. New analysis blames this very unlikely event on chance. But one of the pair may have triggered a third large nearby temblor.Read More »
New evidence about where a major earthquake struck central Washington State 145 years ago raises the possibility that today’s unusually frequent quakes in the area still echo that 1872 event.Read More »Geology & Geophysics
A new finding rests on the recognition that fault types differ between the two regions. It helps explain prior evidence that human-induced quakes and natural ones behave the same in the nation’s center.Read More »Ocean Sciences
Simulations of the historical quake raise new concerns: A similar event in the future could cause a devastating tsunami in Chile’s most populated coastal region.Read More »Geology & Geophysics
A new approach may fine-tune estimates of the range of shaking from earthquakes and help define areas of potential damage.Read More »Mathematical Geophysics
