Sound waves from the Chelyabinsk meteor, which exploded over Russia on 15 February 2013, were detected by 20 infrasound stations that are part of the international monitoring system operated by the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO). The fireball was the most energetic event observed since the 1908 Tunguska meteorite impact and is the most energetic event detected by the CTBTO network.
