In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed the rift was the beginning of a new ocean as two parts of the African continent p...
Earth Sciences |"Looking for something like hurricane records in seismology doesn't occur to anybody," said Carl Ebeling, of Northwestern University in Evanston. "It's a strange and wondrous ...
Earth Sciences |Paul Silver* and Taka'aki Taira of the Carnegie Institution's Department of Terrestrial Magnetism, with Fenglin Niu of Rice University and Robert Nadeau of the University of California, Berk...
Earth Sciences |The team, led by scientists from the University of Edinburgh, says that the new method, which uses data collected from earthquakes, potentially allows the Earth's seismic activity to be mapped mo...
Earth Sciences |Increases in mysterious underground tremors observed in several active earthquake fault zones around the world could signal a build-up of stress at locked segments of the faults and presumably an incr...
Earth Sciences |The special issue will feature seismological research on all aspects of rotational ground motions (including theory, instrumentation, observation, and interpretation) and on rotations in structural re...
Earth Sciences |The study analyzes the interactions on the Moon among electrostatic adhesive forces, the angle of incidence of the sun's rays, and lunar gravity. It concludes that the stickiness of lunar dust on...
Physics and Astronomy |Flying twin-engine light aircraft the equivalent of several trips around the globe and establishing a network of seismic instruments across an area the size of Texas, a U.S.-led, international team of...
Earth Sciences |The slip events coincide with regular occurrences of what scientists call nonvolcanic tremor, which showed up clearly on seismometers but for which the origins were uncertain.Now researchers f...
Earth Sciences |"Using land-based measurement, we can see that over the time periods when the magma is erupting, the ground surface deflates into a bowl of subsidence and when the magma is sealed underground, th...
Earth Sciences |Nestled within the metal pyramid is the heart of the Monterey Accelerated Research System (MARS)-the first deep-sea ocean observatory offshore of the continental United States. Six years and $13.5 mil...
Life Sciences |A group of researchers has presented the new ocean bottom seismometer (OBS) in the magazine IEEE Transactions on instrumentation and measurement. Thanks to its low consumption batteries, the machine c...
Earth Sciences |The 700 km long Talas-Fergana fault in Kyrgyzstan is similar to the San-Andreas fault in the USA and geologists believe the area is highly vulnerable to seismic activity. The fault cuts across...
Studies and Analyses |The geysers of Yellowstone National Park owe their eistence to the "Yellowstone hotspot"--a region of molten rock buried deep beneath Yellowstone, geologists have found. But how hot ...
Earth Sciences |A study by a group of prominent seismologists suggests that a pattern of subtle but active faults makes the risk of earthquakes to the New York City area substantially greater than formerly believed. ...
