Large earthquakes may broadcast warnings, but is anyone tuning in to listen?

12-12-2007 · EurekAlert!

There may be a way to detect the footfalls of large earthquakes a week or more before they strike. A Stanford professor thinks a method to provide such warnings may have been buried in the scientific literature for over 40 years.Antony Fraser-Smith, professor emeritus of electrical engineering and of geophysics, has evidence that big temblors emit a burst of ultra-low-frequency electromagnetic radio waves days or even weeks before they hit.

Scientists launch deep-sea scientific drilling program to study volatile earthquake zone
09-20-2007 · EurekAlert!
Scientists begin exploring the origins of earthquakes at their source with the launch of the Nankai Trough Seismogenic Zone Experiment. On Sept. 21, the Japanese drilling vessel Chikyu departs from Shingu Port with scientists aboard, ready to log, drill, sample and install monitoring instrumentation in one of the most active earthquake zones on Earth. Situated off Japan's southwest coast, the Nankai Trough has generated large-scale earthquakes and tsunamis for millions of years.

Tonga quake not conducive to tsunami
03-12-2007 · EurekAlert!
Seismologists at Washington University in St. Louis and their colleagues in Australia, Japan and Tonga have determined why a large earthquake in Tonga did not cause a large tsunami. A tsunami warning was issued around the Pacific Rim following the magnitude 8.0 earthquake on May 3, 2006, but the resulting tsunami was very minor and caused no damage. It all has to do with Tonga's tearing seafloor.

The area of influence of earthquakes could be larger than is currently thought
11-21-2006 · EurekAlert!
Dr Álvaro Corral, a UAB Department of Physics researcher, studies the relationships between the time and place of earthquake occurrences using statistical physics methods. By analysing data on the distance between consecutive earthquakes, Dr Corral has concluded that the area of influence of seismic activity could be larger than was thought until now.
