It's known that large quakes trigger smaller quakes hours later as the strong seismic waves pass through the Earth. USGS and UC Berkeley seismologists have now shown that at least some large quakes – strike-slip as opposed ...
Researchers have discovered New Zealand's earthquake-prone landscape is even more unstable than previously thought, recording deep tremors lasting up to 30 minutes on its biggest fault line.
A northeast Ohio well used to dispose of wastewater from oil and gas drilling almost certainly caused a series of 11 minor quakes in the Youngstown area since last spring, a seismologist investigating the quakes said Monday.
In the ongoing quest to better anticipate future earthquakes, scientists embarked on an ambitious experiment: Identify the likeliest places where magnitude-4.9 quakes or stronger would occur in seismically active California ...
A rare 5.8 earthquake that rattled the eastern United States on Tuesday was felt over a wide area from Toronto, Canada down to Georgia due to the hard, brittle quality of the ground, experts said.
Researchers believe Colorado River damming projects that followed the creation of the Salton Sea could be one reason why Southern California is overdue for a major earthquake.
Japan's seismologists were so entrenched in outdated beliefs about seismic hazard that they became blinkered to the risk of the March 11 mega-quake, a commentary in a top science journal charged on Wednesday.
Monster earthquakes like the 9.0-magnitude event that occurred off Japan on March 11 are unlikely to trigger a large quake in distant regions of the world, according to a study published on Sunday.
(PhysOrg.com) -- Tokyo may be at serious risk from a massive aftershock and associated tsunami as a result of the devastating March 11 earthquake near Sendai, Japan, according to UC Davis seismologist John Rundle.
