List of meteor air bursts

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Many explosions have been recorded in Earth's atmosphere that are likely caused by the air burst that results from a large meteor burning up as it hits the atmosphere. The best known, and most spectacular was the 1908 Tunguska event. Witnesses often describe the appearance of a bolide such as was seen with the 2012 Sutter's Mill meteorite and 2013 Chelyabinsk meteor. Modern developments in infrasound detection by the Comprehensive Nuclear-Test-Ban Treaty Organization and infrared DSP satellite technology have reduced the likelihood of undetected airbursts.

Date Location Coordinates Yield of explosion (TNT equivalent) Height of explosion Notes
November 15, 1859 (1859-11-15) Near New York City in United States The meteor was witnessed by many in the region, including residents of New York City, as it passed overhead. The fireball exploded over Toms River, New Jersey. The concussion from the explosion shook houses miles from the epicenter. The sound from the explosion lasted for nearly two minutes, and was described as continuous cannon fire.[1][2]
