Earthquake Forecasting. The Future
Posted by Don in Hollister on October 21, 2003 at 02:48:04:

Hi All. This may or may not be what the future earthquake forecasts may be based on, but it does appear to be promising. Certainly it’s a lot better then what we currently have. Take Care…Don in creepy town

“August 11, 2003: For many people, earthquakes are synonymous with unpredictability. They strike suddenly on otherwise normal days, and despite all the achievements of seismology, scientists still can't provide warning of an impending quake in the way that weathermen warn of approaching storms.”

“Although earthquakes seem to strike out of the blue, the furious energy that a quake releases builds up for months and years beforehand in the form of stresses within Earth's crust. At the moment, forecasters have no direct way of seeing these stresses or detecting when they reach critically high levels.”

“That may be changing, however. Satellite technologies being developed at NASA and elsewhere might be able to spot the signs of an impending quake days or weeks before it strikes, giving the public and emergency planners time to prepare.”

“This technique is sensitive enough to detect slow ground motions as tiny as 1 mm per year. That kind of sensitivity, combined with the landscape-wide view that satellites can offer, lets scientists see the tiny motions and contortions of land around a fault line in more detail than ever before. By watching these motions, they can figure out where points of high strain are building up.”
