That's why you haven't heard from them. Anyway, why don't you send them an email and tell them they were part of a major US conspiracy, or whatever. Go on, if you feel so strongly, stick it to them. seismo.ethz.ch > Earthquakes are basically soundless --very low frequencies, infrasounds-- whereas nuclear blasts leave a footprint in the acoustic spectre. Now what are you saying? That seismographs can't detect earthquakes -- or nuclear explosions?! It seems to me you invent science as you go along. How would you explain this?economictimes.indiatimes.com >>Two weeks on, the earth is still vibrating from the massive undersea earthquake off Indonesia that triggered the tsunami, Australian researchers said on Sunday. The Australian National University (ANU) said the reverberations were similar in form to the ringing of a bell, though without the sound, and were picked up by gravity monitoring instruments. “These are not things that are going to throw you off your chair, but they are things that the kinds of instruments that are in place around the world can now routinely measure ,” said ANU Earth Sciences researcher Herb McQueen. “It is certainly above the background level of vibrations that the earth is normally accustomed to experiencing.” The magnitude 9.0 earthquake, the strongest for 40 years, struck off the coast of Indonesia's Sumatra island on December 26. The tsunami it generated claimed more than 156,000 lives. <<
