Slow Earthquakes May Predict Larger Events

Penn State Monitoring slow earthquakes may provide a basis for reliable prediction in areas where slow quakes trigger normal earthquakes, according to Penn State geoscientists. "We currently don't have any way to remotely monitor when land faults are about to move," said Chris Marone, professor of geophysics. "This has the potential to change the game for earthquake monitoring and prediction, because if it is right and you can make the right predictions, it could be big." Marone and...

Slow Earthquakes Take Weeks To Occur

Lee Rannals for redOrbit.com - Your Universe Online Researchers have been aware of slow earthquakes for only the past decade, but little has been understood about them. However, new tools may help explain what triggers these quakes. Scientists thought slow earthquakes were related to the type of rock in the fault, believing that clay minerals are important in slip behavior. A team writing in the journal Nature Geoscience performed laboratory experiments using natural samples taken where...

BSSA is published by the Seismological Society of America. 2010 Haiti quake possible start of new cycle of seismic activity, according to new study. The January 2010 quake that destroyed much of Port-au-Prince may have marked the start of a new cycle of active seismicity, putting Haiti and the Dominican Republic at high risk of future devastating earthquakes. The island of...

  Scientists hope findings bring them closer to earthquake forecasting "What do I remember about an earthquake? I was in the 7th grade. All of a sudden the floor just started shaking. Desks were falling over. Kids were falling on the ground. It was so scary. It happened so quickly!" For people like Tony Zurnick, part of growing up in California was getting caught off guard by the sudden rumbles of earthquakes. Anyone who has lived through a major earthquake will tell you they'd...

Earthquake scientists trying to unravel the mysteries of an unfelt, weeks-long seismic phenomenon called episodic tremor and slip have discovered a strange twist. The tremor can suddenly reverse direction and travel back through areas of the fault that it had ruptured in preceding days, and do so 20 to 40 times faster than the original fault rupture. "Regular tremor and slip goes through an area fairly slowly, breaking it. Then once it's broken and weakened an area of the fault, it can...

Scientists have made the surprising finding that typhoons trigger slow earthquakes, at least in eastern Taiwan. Slow earthquakes are non-violent fault slippage events that take hours or days instead of a few brutal seconds to minutes to release their potent energy. The researchers discuss their data in a study published the June 11, issue of Nature. "From 2002 to 2007 we monitored deformation in eastern Taiwan using three highly sensitive borehole strainmeters installed 650 to 870 feet...

Researchers are using modern technology to study "silent earthquakes" along a major fault zone beneath the Nicoya Peninsula in Costa Rica. Also known as slow slip events, they involve the same motion as an earthquake, but they occur so slowly that they can only be detected by networks of modern instruments. Scientists are using a network of 13 Global Positioning System (GPS) monitoring stations and 13 seismic stations to measure precisely the movements of the Earth's crust on the peninsula...

From June 17-19th 2007, Kilauea experienced a new dike intrusion, where magma rapidly moved from a storage reservoir beneath the summit into the east rift zone and extended the rift zone by as much as 1 meter. Researchers from the University of Hawaii at Manoa (UHM), Scripps Institution of Oceanography at UC San Diego, and the U.S. Geological Survey (USGS) Hawaiian Volcano Observatory have now discovered that the 2007 dike intrusion was not the only action going on: the dike also triggered a...

SAN FRANCISCO (Reuters) - Locating so-called "silent earthquakes" may help scientists better predict the probability of severe temblors, a Stanford University professor said on Wednesday. Silent earthquakes -- slow-moving events tracked by satellites measuring subtle changes on the earth's surface because they do not broadcast shock waves -- appear to build pressure on fault zones, contributing to weak magnitude-two and magnitude-three earthquakes, said Stanford geophysicist Paul...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
