I guess you don't like Stan Deyo either--even though he successfully predicted the Sumatran Tsunami and many since then.

He has more false positives than he probably would wish. But he seems to be on to something about a great temperature differential on opposing sides of a big plate fault being predictive of a significantly increased likelihood of a big quake within several days of such.

ROFL..Stan Deyo...complete fraud and clown.

I'm truly sorry for anyone gullible enough to believe his claims of "successful" earthquake prediction.

People seem to be uniquely susceptible to utter BS when it comes to earthquakes..perhaps only surpassed by "alternative" health quackery.

Deyo basically carpet-bombs the earth with vast areas of vague forecasts day after day (especially making sure that basically every plate boundary is covered with a forecast) such that he can claim a successful prediction for any notable quake.

And that isn't even getting into the area of his methodology being utter nonsense.

ALL VALID QUAKE PREDICTIONS MUST HAVE THESE FOUR COMPONENTS:

1) A SPECIFIC time frame for the forecast (beginning hour/day ending hour/day)

2) A SPECIFIC magnitude range (e.g. between magnitude 5 and magnitude 7)

3) A SPECIFIC land area (either a "box" of latitude/longitude, or a radius around a specific point, that is "within 100 miles of LA City Hall" for example.)

4) Perhaps most importantly, a forecaster needs to calculate HIMSELF the probability he'll have a successful forecast by "dumb luck." This requires work, looking at quake catalogs, but other people shouldn't have to do his work for him.

For example, a forecast of "A magnitude 2.0 or higher quake within 200 miles of LA City Hall from midnight Pacific time 4/19 to midnight 4/26" is a completely worthless forecast, because there's such a quake EVERY week.

Any forecast not containing the above elements is worthless and should be ignored. The main way the uneducated get snowed by bogus quake predictors like Deyo and Berkland is them not understanding the truly huge number of earthquakes that occur on a regular basis, and not understanding statistics...bogus quake predictors make a LOT of VAGUE predictions, and then highlight the significant quakes that end up easily falling into their forecasts,and ignore the others.
