Researchers just discovered a geological hidden passageway.
For some time, seismologists have been aware of brief, subtle anomalies in underground electrical fields leading up to an earthquake, sometimes occurring as soon as a few weeks before the quake happens.
What’s driving Earth’s deepest earthquakes? Diamonds may hold answers.
Abundant data on little quakes can help scientists learn more about what triggers the big ones
An international team led by the Innsbruck geologists Arata Kioka, Tobias Schwestermann, Jasper Moernaut, and Michael Strasser could quantify for the first time the entire trench-wide volume of marine sediments that were remobilized by the magnitude 9 Tohoku-oki earthquake in 2011 and transported into the up to 8 km deep Japan Trench.
A swarm of more than 200 earthquakes struck Yellowstone National Park over the past two weeks, but that probably doesn’t mean the “big one” is coming anytime soon, according to geologists from the park. The 200 temblors began on Feb. 8 and ramped up on Feb. 15 in an area about 8 miles (13 kilometers)
Researchers have developed a new approach to estimate the true size of very large earthquakes.
A tiny slowdown in Earth’s rotation next year could trigger more earthquakes than usual, new research suggests.
A new study along the San Andreas Fault revealed evidence of more ground-rupturing earthquakes in Southern California.
