The activity of the solid Earth—for example, volcanoes in Java, earthquakes in Japan, etc.—is well understood within the context of the ~50-year-old theory of plate tectonics. This theory posits that Earth's outer shell ...

Applying deep learning to seismic data has revealed tremor and slip occur at all times—before and after known large-scale slow-slip earthquakes—rather than intermittently in discrete bursts, as previously believed. Even ...

Up to now, there was no way of predicting whether a powerful earthquake was likely to be followed by one of even greater magnitude. But the results of a study recently published in Nature by Laura Gulia and Stefan Wiemer ...

A devastating wall of water gushed down the Bhotekoshi/Sunkoshi River in Nepal on July 5, 2016. It came from a lake that had been dammed by a glacial moraine, but the dam broke and discharged more than 100,000 tons of water ...

A comprehensive analysis of 101 major earthquakes around the Pacific ring of fire between 1990 and 2016 shows that most of the aftershock activity occurred on the margins of the areas where the faults slipped a lot during ...

(Phys.org)—A trio of researchers with Istituto Nazionale di Geofisica e Vulcanologia in Italy has created an earthquake warning system that reliably predicted a series of aftershocks after a major quake in Italy. In their ...
Major earthquakes - magnitude 8.5 and stronger—occur where faults are mostly flat, say University of Oregon and French geologists. Curvier faults, they report in the journal Science, are less likely to experience earthquakes ...

The main fault at the foot of the Himalayan mountains can likely generate destructive, major earthquakes along its entire 2,400-kilometer (1,500-mile) length, a new study finds. Combining historical documents with new geologic ...
