Scientists Warn Of Major Earthquakes In Himalayas And Pacific Northwest
2012-12-04 15:18:09

Lee Rannals for redOrbit.com — Your Universe Online Scientists at the American Geophysical Union meeting in San Francisco this week reported that the Himalayas and Pacific Northwest could experience major earthquakes. Researchers have begun studying the complexity of the Himalayan range in greater detail, particularly the fault that separates the two plates known as the Main Himalayan Thrust (MHT). Previous observations indicated a fault that dipped a few degrees to the...

Deep Tectonic Tremors Provide Clues About Shallow Earthquakes

Brett Smith for redOrbit.com - Your Universe Online Although the earth is shaken by approximately 80,000 earthquakes every month, not many of them will send you running for the nearest doorway. However, scientists, led by a team at Karlsruhe Institute of Technology (KIT) in Germany, have recently started investing more time and research into understanding these subtle vibrations that occur deep in the Earth´s crust. More specifically, these researchers are interested in tectonic...

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...

Just a few years ago, Dan Farber happened to be doing field work in Peru with students when the 8.0 Pisco earthquake struck. As a scientist working in the active tectonics of the Peruvian Andes - funded through the Lawrence Livermore National Laboratory's Institute for Geophysics and Planetary Physics - Farber was asked by colleagues if he could participate in a rapid response team to map the damage of the seismic deformation and install a system of geodetic stations. He jumped at the...

For most of a decade, scientists have documented unfelt and slow-moving seismic events, called episodic tremor and slip, showing up in regular cycles under the Olympic Peninsula of Washington state and Vancouver Island in British Columbia. They last three weeks on average and release as much energy as a magnitude 6.5 earthquake. Now scientists have discovered more small events, lasting one to 70 hours, which occur in somewhat regular patterns during the 15-month intervals between episodic...

In the last decade, scientists have recorded regular episodes of tectonic plates slowly, quietly slipping past each other in western Washington and British Columbia over periods of two weeks or more, releasing as much energy as a magnitude 6 earthquake. 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 from Italy and the University of Washington have...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
