Hi all, Noted a mention to the chicxulub asteroid impact in a paper clipping with regard to the equivalent earthquake magnitude. According to a geophysicist, Brian Toon, at the University of Colorado in Boulder; it was equivalent to a magnitude 12-13, far greater than any known earthquake. The clipping mentions ground upheaval for hundreds of yards; as far as 600 miles from ground zero. The suggestion of such seismic upheaval sounds like it might stimulate alot of the impact or earth anti-pod (at that time), lava activation proponents. The June issue of the Journal Geology is supposed to have a article relating to this event/extinction period, although I've not seen it.
