Earthquake Prediction

So far earthquake engineering (i.e. efficient and economic design of structures that may have to withstand the shaking of earthquakes) risk analysis, hazard maps, land-use regulation, building codes and disaster preparedness have done more to reduce casualties and lower economic losses than earthquake predictions.

In May 1975 Scientific American wrote the following about earthquake prediction: “Recent technical advances have brought long-sought goals within reach. With adequate funding several countries, including the U.S, could achieve reliable long-term and short-term forecasts in a decade.”

Today 30 years (that is three decades) later a new report published by Nature disclosed that a long-term study in the U.S. (California) aimed at predicting earthquakes has ended in a sad failure.

To a certain extent scientists can predict location and size, but the timing is obviously a great problem – leaving people in Kashmir and other quake prone regions unprepared.
Earthquake prediction is still an imprecise science.

Earthquake Prediction is Improving ...

World - Earthquake and Tsunami Prediction. Based on animal behaviour. Keep your pet on a leash when risk is greater than 40%. Note; A risk of 80% or higher indicates the possibility of a tsunami. We forecast earthquakes greater than 6.3. Forecasts made in Eastern Time Zone USA 7.0-7.9 Major earthquake. Can cause serious damage over larger areas. 8 or greater Great earthquake. Can cause serious damage in areas severalhundred kilometers across. http://www.colorwize.com/Earthquake%20Prediction.html

I don't think earth quake prediction has made a huge jump forward since 2005, or am I wrong? And yet here is a guy who seems to know that the North American Pacific coast is in for a big earthquake soon: http://www.newsweek.com/2011/03/13/the-scariest-earthquake-is-yet-to-come.html

(found it via http://twitter.com/#!/Allochthonous/status/50038835190579200)

Now, it's a safe bet that there will be further big earthquakes along the San Andreas fault in the future, I suppose. But the following claim reads like pure scaremongering:

"It is as though the earth becomes like a great brass bell, which when struck by an enormous hammer blow on one side sets to vibrating and ringing from all over. Now there have been catastrophic events at three corners of the Pacific Plate—one in the northwest, on Friday; one in the southwest, last month; one in the southeast, last year. That leaves just one corner unaffected—the northeast. And the fault line in the northeast of the Pacific Plate is the San Andreas Fault"

That sounds like rubbish to me.

Chris Rowan is more polite by calling it "some rather strange ideas about quake triggering".

It must be fun to be a "geo-popularizer". I wonder wether I should get in on that racket? I could write a book about "Runaway subduction reloaded: All you need to know about emergency sheep building and why you'll need it soon".
