"The shockwave generated by the explosion of an asteroid over Russia’s Chelyabinsk was so powerful that it traveled some 85,000km, circling the globe twice over the course of three days, a new study says. The effect of the event was detected by the network of infrasonic stations, which are operated by the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) to detect evidence of atmospheric nuclear explosions. The data supplied by 20 infrasound stations of the International Monitoring System (IMS) network shows that the shockwave travelled at the speed of about 340 meters per second (1,224km per hour). The latest detections came almost three days after the fireball wrecked destruction in the Urals Mountains city, which gave the researchers the distance traveled. The scientists estimated energy yield of the explosion at about 460 kilotons of TNT equivalent, which is about the same as a thermonuclear W88 warhead carried by the Trident II missile."
