"Western experts are said to be astonished that such a weapons program was ever attempted. Many believe the notion of triggering and controlling earthquakes is pure science fiction."<<

Oh yes... everything is science fiction, until it is done. Going to the moon is science fiction, cloning is science fiction, and one nation posessing the ability to incinerate the globe several times over is science fiction.

On February 28, 2001, a deep magnitude 6.8 earthquake occurred in the Seattle, WA. -Vancouver, B.C. area. HAARP began bombarding the earth's ionosphere and magnetosphere at very high signals on February 17 in conjunction with US bombing in Iraq and continued until the day of the earthquake, February 28. Looking at data correlations between ultra low frequency electromagnetic and seismic signals, the anomalous profile of the Seattle-Vancouver earthquake indicates that it could have been triggered by electromagnetic ionization. The earthquake was a 6.8 magnitude earthquake at a depth of 40 miles, which, in the words of one observer, "looked like a 3.0 magnitude."

ELFRAD, a group that monitors electromagnetic events, admitted that HAARP operations may have "inadvertently" affected the earthquake. HAARP currently functions as a global missile-tracking facility by ionizing and disrupting both the ionosphere and the magnetosphere. The magnetosphere is vital to the stability of the tectonic plates that float on the surface of the earth. By disrupting the magnetosphere, HAARP could cause tectonic instabilities, i.e., earthquakes.
