Seismic Global Activity & Nuclear Underground Testing, Bad Combo.

  1. Mar 26, 2004 #1
    Hello All,

    I've always been curious about historical seismic activity prior to the 20th century. Then the advent of the last century until now, i have heard that seismic activity has increased dramatically.

    Then i got to conceptualizing how many underground nuclear test's have been conducted in our combined history to present?

    I read somewhere it is in the thousands, recently a couple of years ago India & Pakistan both denoted their first nukes underground. Where do all those shock waves go once a nuclear bomb is set off underground? Does it just dissapate from a torrent to that of a lingering vibration hundreds of miles away sonically?

    I'm guessing that a geologist, volcanist, and a nuclear physicist can help answer this preliminary theory. What if in our past one of these nukes were denoted near a seismic fault line or dormant volcano? Would the sonic impact to such tectonic plates mearly absorb the energy. Or somehow accerelate seismic activity on our planet worldwide. Perhaps like winding up a "jack in the box" until the eventual pop takes effect in a series of earthquakes or volcanic blasts.

    Has there been any talk of any such studies being conducted? Perhaps mathematically calculating the combined impact of all global nuclear denonations. In terms of kinenetic energy released underground, while having a overlay seismic map of any nearby fault lines and other geological activity landmarks. (such as volcano's, etc..)

    I'm always been curious of this, but i'm just a hobbyist conceptual builder.

    a Nuke might cause some small scale tremors to come out of a fault line, but that would not cause global increases in tectonic activity.

    this perception that a nuclear bomb is some sort of super weapon capable of blowing the planet into an asteroid belt is ridiculous. all you get is a really big explosion and in the case of a Plutonium bomb, a lot of radiation that is hard to clean up.

    I would also suggest that perhaps the increase in recorded siesmic activity is largely due to the increase in seismic monitoring. Since the invention of the seismometer, geologists have recorded dozens of tremors per day that went undetected before.
