![]() It is estimated that, in some places, the resulting shock wave was equivalent to an earthquake measuring 5.0 on the Richter magnitude scale. The explosion registered at seismic stations across Eurasia, and air waves from the blast were detected in Germany, Denmark, Croatia, and the United Kingdom-and as far away as Batavia, Dutch East Indies, and Washington, D.C. The sounds were accompanied by a shock wave that knocked people off their feet and broke windows hundreds of kilometres away. Eyewitnesses closer to the explosion reported that the source of the sound moved from the east to the north of them. About ten minutes later, there was a sound similar to artillery fire. The pillar split in two and faded, turning to black. Closer to the horizon, there was a flash producing a billowing cloud, followed by a pillar of fire that cast a red light on the landscape. S., before the implementation of the Soviet calendar in 1918), at around 07:17 local time, Evenki natives and Russian settlers in the hills northwest of Lake Baikal observed a bluish light, nearly as bright as the Sun, moving across the sky and leaving a thin trail. Location of the event in Siberia (modern map) It has been mentioned numerous times in popular culture, and has also inspired real-world discussion of asteroid impact avoidance. An explosion of this magnitude would be capable of destroying a large metropolitan area. The Tunguska event is the largest impact event on Earth in recorded history, though much larger impacts have occurred in prehistoric times. It is classified as an impact event, even though no impact crater has been found the object is thought to have exploded at an altitude of 5 to 10 kilometres (3 to 6 miles) rather than having hit the surface of the Earth. 178 The asteroid approached from the east-southeast, and likely with a relatively high speed of about 27 km/s (60,000 mph) (~ Ma 80). The explosion is generally attributed to a meteor air burst: the atmospheric explosion of a stony asteroid about 50–60 metres (160–200 feet) in size. The explosion over the sparsely populated Eastern Siberian Taiga flattened an estimated 80 million trees over an area of 2,150 km 2 (830 sq mi) of forest, and eyewitness reports suggest that at least three people may have died in the event. The Tunguska event (occasionally also called the Tunguska incident) was an approximately 12- megaton explosion that occurred near the Podkamennaya Tunguska River in Yeniseysk Governorate (now Krasnoyarsk Krai), Russia, on the morning of June 30, 1908.
