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.
