Plates at subduction zones typically move just a few centimeters per year. But when accumulated stress at these convergent plate boundaries releases suddenly, the plates can slip several meters and ...

Two strong earthquakes struck Japan Tuesday at magnitudes of 5.4 and 4.7, according to data from the United States Geological Survey (USGS). The first quake struck in the Pacific Ocean about 80 miles ...

Seismologists have classified the event as a rare earthquake doublet, in which two major earthquakes of similar strength ...

The vertical components of all four earthquakes were analyzed. The Japanese earthquakes were recorded using short-period seismometers at Hi-net borehole stations deeper than 100m 33 operated by the ...

Researchers have developed a laboratory earthquake model that connects the microscopic real contact area between fault surfaces to the possibility of earthquake occurrences. Published in the ...
