New analysis of earthquake zone raises questions

Space & Earth / Earth Sciences

Aug 26, 2008 | 4.4 / 5 (11) | 0

Oregon State University scientists have completed a new analysis of an earthquake fault line that extends some 200 miles off the southern and central Oregon coast that they say is more active than the San Andreas Fault in ...

New study cites lower rate of quakes along some subduction zones

Most earthquakes occur along fault lines, which form boundaries between two tectonic plates. As the relative speed of the plates around a fault increases, is there a corresponding increase in the number of earthquakes produced ...

New way to monitor faults may help predict earthquakes

(PhysOrg.com) -- U.S. seismologists have found evidence that the massive 2004 earthquake that triggered killer tsunamis throughout the Indian Ocean weakened at least a portion of California's famed San Andreas ...

Using new technique, scientists find 11 times more aftershocks for 2004 quake

Natural gas that lies under Turkey's Marmara Sea close to Istanbul could provide advance warning of an earthquake experts believe will hit the country's largest city, scientists said on Tuesday.

New study sheds light on earthquake hazard along San Andreas Fault

Space & Earth / Earth Sciences

Jul 27, 2009 | 3.7 / 5 (3) | 1

New research by a team of scientists from Scripps Institution of Oceanography at UC San Diego and the U.S. Geological Survey (USGS) offers new insight into the San Andreas Fault as it extends beneath Southern ...

Fault weaknesses, the center cannot hold for some geologic faults

Space & Earth / Earth Sciences

Dec 16, 2009 | 5 / 5 (4) | 0

Some geologic faults that appear strong and stable, slip and slide like weak faults. Now an international team of researchers has laboratory evidence showing why some faults that "should not" slip are weaker ...

Sichuan quake was once-in-4,000-year event: scientists

Space & Earth / Earth Sciences

Sep 27, 2009 | 3.8 / 5 (5) | 3

People who were killed, injured or bereaved in the 2008 Sichuan earthquake had the cruel misfortune to be victims of an event that probably occurs just once in four millennia, seismologists said on Sunday.

Deep creep means milder, more frequent earthquakes along Southern California's San Jacinto fault

Space & Earth / Earth Sciences

Nov 08, 2009 | 3.8 / 5 (6) | 1

With an average of four mini-earthquakes per day, Southern California's San Jacinto fault constantly adjusts to make it a less likely candidate for a major earthquake than its quiet neighbor to the east, the ...
