Tectonic weapon
Encyclopedia
A tectonic weapon is a hypothetical device or system by which a nation could create earthquake
Earthquake
An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time...

: "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".

 in 1996, responding to a newspaper report that there had been two secret Soviet programs, "Mercury" and "Volcano", aimed at developing a "tectonic weapon" that could set off earthquakes from great distance by manipulating electromagnetism, said "We don't think it is impossible, or wrong, but past experience suggests it is very unlikely". According to Nature these programs had been "unofficially known to Western geophysicists for several years". According to the story the Mercury program began in 1987, three tests were conducted in Kyrgyzstan, and Volcano's last test occurred in 1992.

Such weapons, whether or not they exist or are feasible, are a source of concern in official circles. For example US Secretary of Defense William S. Cohen, said on 28 April 1997 at the Conference on Terrorism, Weapons of Mass Destruction, and U.S. Strategy, University of Georgia "Others are engaging even in an eco-type of terrorism whereby they can alter the climate, set off earthquakes, volcanoes remotely through the use of electromagnetic waves."
