Is there a "machine" that can cause earthquakes? There is more than one.
EISCAT (European Incoherent Scatter Scientific Association) operates an ionospheric heating facility capable of transmitting over 1 GW (1,000,000,000 watts) effective radiated power (ERP), near Tromsø in Norway.
Russia has the Sura ionospheric heating facility, in Vasilsursk near Nizhniy Novgorod, capable of transmitting 190 MW ERP.
There is another site operated by a military subcontractor under an arrangement between the US and Canadian governments. It is located near Cape Race, Newfoundland, Canada (N46° 38.649' W53° 9.010'). Since this site originally had minimal to no grid power available, it may be a passive listening post for transmissions emitted by other HAARP sites.
In August 2002, further support for those critical of HAARP technology came from the State Parliament (Duma) of Russia. The Duma published a report on HAARP written by its International Afairs and Defense Committees. It was signed by 90 deputies and presented to President Vladimir Putin.
The report claimed that "the U.S. is creating new integral geophysical weapons that may influence the near-Earth medium with high-frequency radio waves... The significance of this qualitative leap could be compared to the transition from cold steel to firearms, or from conventional weapons to nuclear weapons. This new type of weapons differs from previous types in that the near-Earth medium becomes at once an object of direct influence and its component."
However, given the timing of the Russian intervention, it is possible that it was related to a controversy at the time concerning the US withdrawal in June 2002 from the Russian-American Anti-Ballistic Missile Treaty.
This high level concern is paralleled in the April 1997 statement by the U.S. Secretary of Defense over the power of such electromagnetic weaponry.
Russia owns and operates an ionospheric heater system as powerful as HAARP called Sura, located roughly 150 km from the city of Nizhny Novgorod.
The objectives of HAARP became the subject of controversy in the mid-1990s, following claims that the antennas could be used as a weapon.
A small group of American physicists aired complaints in scientific journals such as Physics and Society. They charged that the HAARP project could be seeking ways to destroy or disable enemy spacecraft or disrupt communications over large portions of the planet.
The physicist-critics were not complaining about the project's initial stages. They were expressing fears that HAARP could be expanded into a weapon. That this is where it was headed was apparent by its funding. It was coming from the Office of Naval Research and the Air Force Research Laboratory.
These concerns were amplified by Bernard Eastlund, a physicist who developed some of the concepts behind HAARP in the 1980s and proposed using high-frequency radio waves to beam large amounts of power into the ionosphere. This would energize its electrons and ions and disable incoming missiles with the idea of knocking out satellite communications.
The US military became interested in the idea as an alternative to the laser-based "Star Wars" Strategic Defense Initiative (SDI). However, Eastlund's ideas were eventually dropped as SDI mutated into the limited National Missile Defense. Contractors selected to build HAARP have denied that any of Eastlund's patents were used in the development of the project.
After the physicists raised early concerns, controversy was stoked by local activism. In September 1995, a book entitled Angels Don't Play This HAARP: Advances in Tesla Technology by Nick Begich, Jr. -- son of the late Congressman Nick Begich (D-AK) and brother of US Senator Mark Begich (D-AK) -- claimed that the project in its present stage could be used for "geophysical warfare."
