Tectonic weapon Tectonic weapon A tectonic weapon is a hypothetical device or system which could create earthquakes, volcanoes, or other seismic events in specified locations by interfering with the Earth's natural geological processes. It was defined in 1992 by Aleksey Vsevolovidich Nikolayev, corresponding member Russian Academy of Sciences: "A tectonic or seismic weapon would be the use of the accumulated tectonic energy of the Earth's deeper layers to induce a destructive earthquake". He added "to set oneself the objective of inducing an earthquake is extremely doubtful". Theoretically, the tectonic weapon functions by creating a powerful charge of elastic energy in the form
