Many explosions recorded in Earth's atmosphere are likely to be caused by the air bursts that result from meteors exploding as they hit the thicker part of the atmosphere. These types of meteors are also known as fireballs or bolides with the brightest known as superbolides. Before entering Earth's atmosphere, these larger meteors were originally asteroids and comets of a few to several tens of metres in diameter, contrasting with the much smaller and much more common "shooting stars". The most powerful recorded air burst is the 1908 Tunguska event. Extremely bright fireballs traveling across the sky are often witnessed from a distance, such as the 1947 Sikhote-Alin meteor and the 2013 Chelyabinsk meteor, both in Russia. If the bolide is large enough, fragments may survive such as the Chelyabinsk meteorite. Modern developments in infrasound detection by the Comprehensive Nuclear-Test-Ban Treaty Organization and infrared Defense Support Program satellite technology have increased the likelihood of detecting airbursts.
The table from Earth Impact Effects Program (EIEP) estimates the average frequency of airbursts and their energy yield in kilotons (kt) or megatons (Mt) of TNT equivalent.

While airbursts undoubtedly happened prior to the 20th century, reliable reports of such are quite scanty. A possible example is the 1490 Ch'ing-yang event, which had an unknown energy yield but was reportedly powerful enough to cause 10,000 deaths.[3] Modern researchers are sceptical about the figure, but had the Tunguska event occurred over a highly populous district, it might have caused a similar level of destruction.[3] A study published in 2020 claimed that on 22 August 1888, a meteorite killed a man and left another paralyzed in Sulaymaniyah, Iraq, as reported by the local governor to Sultan Abdul Hamid II of the Ottoman Empire.[4]
Depending on the estimate, there were only 3–4 known airbursts in the years 1901–2000 with energy yield greater than 80 kilotons (in 1908, 1930?, 1932?, and 1963), roughly consistent with the estimate of the EIEP table. Most values for the 1930 Curuçá River event put it well below 1 megaton.[5][6][7] The Comprehensive Nuclear-Test-Ban Treaty Organization and modern technology has improved multiple detection of airbursts with energy yield 1–2 kilotons every year within the last decade.[8]
The first airburst of the 21st century with yield greater than 100 kilotons came from the 2013 Chelyabinsk meteor, which had an estimated diameter of 20 metres.

2017, Nov 16 | Europe: Inari, Finland | 69°06′N 28°36′E / 69.1°N 28.6°E / 69.1; 28.6 | 20–91 km | A meteoroid weighing a few hundred kg exploded in an airburst and dropped tens of kg of meteorites into a remote area of Finnish Lapland.[80] The resulting shockwave was felt on the surface.[81] The event was detected by 7 infrasound stations.[82] | |
2017, Dec 15[8] | Russia: Kamchatka | 60°12′N 170°00′E / 60.2°N 170.0°E / 60.2; 170.0 | 6.4 kilotonnes of TNT (27 TJ) | 20 km (12 mi) | The asteroid likely had a diameter of 2–5 meters prior to impact. But because it happened in a remote area in Kamchatka, there were likely no eyewitnesses. The event was detected at 11 CTBTO infrasound stations.[83] |
2018, Jan 22[8] | Atlantic Ocean: off Senegal's coast | 14°00′N 17°24′W / 14.0°N 17.4°W / 14.0; -17.4 | 0.11 kilotonnes of TNT (0.46 TJ) | Not related to ATLAS detected object A106fgF that had an impact track well south of Senegal. | |
2018, Jun 21[8] | Russia : Kursk Oblast | 52°48′N 38°06′E / 52.8°N 38.1°E / 52.8; 38.1 | 2.8 kilotonnes of TNT (12 TJ) | 27.2 km (16.9 mi) | Loud sonic booms were reported[84] as well as fragments found.[85] |
2018, Dec 18[8] | Bering Sea, near Kamchatka, Russia | 56°54′N 172°24′E / 56.9°N 172.4°E / 56.9; 172.4 | 173 kilotonnes of TNT (720 TJ) | 25.6 km (15.9 mi) | Kamchatka superbolide asteroid (~10 meters in diameter) impacting at a fast 32 km/s. Largest airburst since Chelyabinsk.[86] |
2019, Feb 18[8] | Africa: Zambia | 15°30′S 25°18′E / 15.5°S 25.3°E / -15.5; 25.3 | 4.2 kilotonnes of TNT (18 TJ) | 26 km (16 mi) | |
2019, June 22[8] | Caribbean Sea | 14°54′N 66°12′W / 14.9°N 66.2°W / 14.9; -66.2 | 6 kilotonnes of TNT (25 TJ) | 25 km (16 mi) | 2019 MO (~3 meters in diameter) seen by ATLAS 12 hours before impact. |
2020, December 22[8] | Qinghai province, China | 31°54′N 96°12′E / 31.9°N 96.2°E / 31.9; 96.2 | 9.5 kilotonnes of TNT (40 TJ) | 35.5 km (22.1 mi) | Asteroid (~8 meters in diameter) impacting at a relatively slow 13.6 km/s. Largest known impact since 2018 December 18. |
Note: For sorting purposes, location is given in "general:specific" format. For example, "Europe: Spain". This table contains a chronological list of events with a large yield at least 3 kilotons since 2005, with earlier or smaller events included if widely covered in the media.
As of January 2020, the number of airbursts each year since 2005, as reported in the JPL Fireball and Bolide Reports are:[8]
