Latest Episodic tremor and slip Stories
Scientists at the American Geophysical Union meeting in San Francisco this week reported that the Himalayas and Pacific Northwest could experience major earthquakes.
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.
Earthquake scientists trying to unravel the mysteries of an unfelt, weeks-long seismic phenomenon called episodic tremor and slip have discovered a strange twist.
Just a few years ago, Dan Farber happened to be doing field work in Peru with students when the 8.0 Pisco earthquake struck.
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.
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.
