'Virtual earthquakes' used to forecast Los Angeles quake risk
Stanford scientists are using weak vibrations generated by the Earth's oceans to produce "virtual earthquakes" that can be used to predict the ground movement and shaking hazard to buildings from real quakes.
Eight seconds of terror
(Phys.org) —Twenty years ago this week, in the predawn darkness of Jan. 17, 1994, at five seconds before 4:31 a.m. PST, the ground ruptured violently on a blind thrust fault (a crack in Earth's crust that ...
Earthquake lights linked to rift environments, subvertical faults
Rare earthquake lights are more likely to occur on or near rift environments, where subvertical faults allow stress-induced electrical currents to flow rapidly to the surface, according to a new study published ...
Slippery fault unleashed destructive Tohoku-Oki earthquake and tsunami
For the first time, scientists have measured the frictional heat produced by the fault slip during an earthquake. Their results, published December 5 in Science, show that friction on the fault was remark ...
Scientists calculate friction of Japan's 9.0 earthquake in 2011
An international team of scientists that installed a borehole temperature observatory following the 2011 Tohoku-Oki earthquake in Japan has been able to measure the "frictional heat" generated during the rupture of the fault ...
Strong earthquake hits Indonesia; no casualties
A strong, shallow earthquake rocked parts of eastern Indonesia early Sunday, but there were no immediate reports of damage or injuries.
Strong earthquake rocks eastern Indonesia
A strong undersea earthquake shook eastern Indonesia on Tuesday, but there were no immediate reports of serious damage or casualties.
Study links earthquake faults to slow-moving depths
(Phys.org) —Most earthquakes erupt suddenly from faults near Earth's surface, and the big ones can topple cities. But miles below, rocks heated to the consistency of wax moving over thousands to millions ...
Quakes rattle Spain, offshore gas storage project blamed
Hundreds of small earthquakes which have rattled Spain's eastern coast were blamed Wednesday by green groups and geologists on a large offshore gas storage plant that started operating in June.
Report: Tsunami would swamp California's economy (Update)
If a monster earthquake struck off Alaska's coast, tsunami waves would rush toward California, crippling the nation's busiest port complex and flooding coastal communities, a report released Wednesday suggests.
SF Bay Area building demolition fuels quake study (Update)
It took just seconds for a 13-story building overlooking San Francisco Bay to implode, spewing smoke and chunks of concrete as it crumbled into a heap of rubble. But U.S. Geological Survey scientist Rufus ...
