I like reading conspiracy theories - not because I believe them easily but because they are in most cases very creative and reveal interesting information and other views at our world. I can recommend watching this this youtube video
with some very interesting statements.
Should this be true (who knows), then something like an earth quake weapon exists: The Ionosphere is pushed up by the HAARP
, causing an earth quake when it rebounces.
Seen in action lately in China (remember the strange lights reported shortly before the earthquake
?) or in Niigata, Japan 2007, where the epicenter was curiously enough exactly Japan's biggest nuclear plant. Oddly enough, also in China the epicenter was quite near to a military nuclear facility, it seems.
So I hope this one really is a conspiracy theory. :)
