The impact of meteorites in Russia spread throughout the world

Sensors in Africa, Greenland and many other places discovered seismic shock from a meteorite explosion in Russia on February 15.

The Comprehensive Nuclear Trial Treaty Organization (CTBTO) implements a sensor system across the globe to detect sound waves from nuclear weapons tests. Since February 15, about 11 sensors on Greenland, Africa, Kamchatka Peninsula of Russia and many other areas have received negative waves from meteorite explosions in central Russia, Livescience reported. .

Negative waves (with frequencies from about 20 to 0.0 Hertz, lower than the threshold that humans can hear) spread far in the air. Elephants, pigeons and whales use sound waves to communicate and orient.

If a nuclear weapons test takes place, the sound waves from the explosion will spread to CTBTO sensors. Based on the negative wave, CTBTO experts will determine the location and scale of the explosion. Human-induced explosions (like bombing) create different types of sound waves than artificial explosions (like meteor explosions).

With data on the sound waves that sensors receive, scientists from the US Aerospace Agency (NASA) conclude that meteorites in Russia have a volume of up to 10,000 tons and the energy it releases. about 300 kiloton, equivalent to the power of 20-25 atomic bombs falling on the Japanese city of Hiroshima during World War II.

"It's a medium-sized meteorite explosion , " said Paul Chodas, a scientist from NASA's Near-Earth Objects Program.
