China and Russia have modified an important layer of the atmosphere above Europe to test a controversial technology for possible military application, according to Chinese scientists involved in the project.

A total of five experiments were carried out in June. One, on June 7, caused physical disturbance over an area as large as 126,000 sq km (49,000 square miles), or about half the size of Britain.

The modified zone, looming more than 500km (310 miles) high over Vasilsursk, a small Russian town in eastern Europe, experienced an electric spike with 10 times more negatively charged subatomic particles than surrounding regions.

In another experiment on June 12, the temperature of thin, ionised gas in high altitude increased more than 100 degrees Celsius (212 degrees Fahrenheit) because of the particle flux.

The particles, or electrons, were pumped into the sky by Sura, an atmospheric heating facility in Vasilsursk built by the former Soviet Union’s military during the cold war.

A Russian geophysical weapon equivalent to the American HAARP installed in Alaska could cause earthquakes from anywhere in the world. The SURA, located near the small town of Vasilsursk about 100 km east of Nizhniy Novgorod, Russia, would have the same capacity for the HAARP, and can cause seismic movements in non-seismic areas like the East coast of the USA, where the majority of nuclear power plants in the country accumulates. The ghost of Fukushima fly over North America.

SURA ionospheric heating facility, is a center of research of the ionosphere located near the small town of Vasilsursk about 100 km east of Nizhniy Novgorod, Russia. Sura is capable of radiating about 190 MW, effective radiated power (PRE) on shortwave. Initially depended on the Ministry of defence, but this service is currently operated by the Research Institute of Radio NIRFI in Nizhny Novgorod.

The Sura facility was commissioned in 1981. With the use of this mechanism, Russian researchers study the behaviour of the ionosphere and the effect of the generation of emission of low-frequency modulation of the ionosphere.

The range of frequencies of the installation is 4.5 to 9.3 MHz. The facility consists of three transmitters broadcasting of 250 kW and an antenna crossed dipole 144 with dimensions of 300 m x 300 m. In the center of the frequency range of operation (4.5 – 9.3 MHz), as peak gain is reached around 260 (~ 24 dB), the effective radiated power (PER) of the facility is 190 MW (~ 83 dBW).
