Initial earthquake behavior does not predict outcome

Can seismologists tell from the first few seconds of recorded seismic data how big an earthquake is going to be, or does it take longer and require data that come in after a quake rupture has progressed along the fault? The answer to this question underpins the usefulness of earthquake early warning systems and has perplexed scientists for decades. In a new study, researchers looking at near-source seismic recordings from shallow crustal earthquakes have found that, within the first few seconds of rupture, large and small earthquakes appear indistinguishable from one another, hinting that initial rupture behavior may be universal among variously sized events.

Vital seconds: The journey toward earthquake early warning for all

People living along the U.S. West Coast are keenly aware that they live near faults that could quake at any moment. The good news is that earthquake early warning — providing warnings seconds to minutes before damaging seismic waves hit — is progressing from being just a good idea to reality.

Seismic citizens: Volunteers host home-based seismometers to help assess earthquake threat

A network of volunteer hosts and home-based seismometers around Washington’s Puget Sound region report earthquake data to the U.S. Geological Survey (USGS) and the Pacific Northwest Seismic Network (PNSN) through the volunteer-powered NetQuakes program. Driven by a desire to to help the area better prepare for future large earthquakes, to be part of a group effort, and by an abiding (though not necessarily professional) interest in science and technology, the members of this unusual family are part of a growing movement in earthquake research and monitoring that is making use of the explicit support of citizen scientists.

Behind the scenes with NetQuakes' Doug Gibbons

Doug Gibbons, a research assistant in the University of Washington’s Department of Earth and Space Sciences and a NetQuakes technician, is one of several people involved in managing and maintaining the Pacific Northwest Seismic Network’s (PNSN) portion of the U.S. Geological Survey (USGS) NetQuakes program. Having installed many of PNSN’s NetQuakes seismometers, he is a point man for outreach and interaction with current and prospective volunteers.

Hazardous Living: Collision forces behind devastating Turkey quake

By Tuesday evening local time, close to 500 people have been confirmed dead and more than 1,300 injured following a major magnitude-7.2 earthquake that struck eastern Turkey on Sunday at 1:41 p.m. local time. Countless people are still trapped under debris after the shallow quake, only 20 kilometers deep, leveled at least 2,260 buildings in Van, Ercis and other cities and villages, according to news reports.
