![]() Sikhote-Alin is the largest meteorite fall of our time. At an altitude of about 5.6 km (3.5 mi), the largest mass apparently broke up in a violent explosion called an air burst. Amazing meteorite shrapnel form in the explosive entry of the meteor. The Sikhote-Alin meteorite fall was a massive impact event that occured on February 12th 1947, approximaetely 440km northeast. This meteorite is presented in a neat display box with an information leaflet. A smoke trail, estimated at 32 km (20 mi) long, remained in the sky for several hours.Īs the meteor, traveling at a speed of about 14 km/s (8.7 mi/s), entered the atmosphere, it began to break apart, and the fragments fell together. This Sikhote-Alin Meteorite was part of a huge fall that occurred in February 1947 in the Sikhote-Alin Mountains NE of Vladivostok, Russia. Additionally, these massive meteorites left impact craters, some as big as 85 feet across and 20 feet deep. Sikhote-Alin Iron Meteorite encourages the being to respect and nurture the whole self, as well as surroundings. Scientists estimate that its mass was approximately 220,000 lbs (100,000 kg) before it entered Earth’s atmosphere. ![]() The bright flash and the deafening sound of the fall were observed for 300 kilometres (190 mi) around the point of impact not far from Luchegorsk and approximately 440 km (270 mi) northeast of Vladivostok. The Sikhote-Alin meteorite fall is one of the largest in recorded history. An estimated 23 tonnes of fragments survived the fiery passage through the atmosphere and reached the Earth, but still less than the largest meteorite find, the Hoba meteorite of 60 tonnes.Īt around 10:30 on 12 February 1947, eyewitnesses in the Sikhote-Alin Mountains, Primorye, Soviet Union, observed a large bolide brighter than the sun that came out of the north and descended at an angle of about 41 degrees. As the 100,000kg meteorite travelling at a speed of about 14 km/s entered the atmosphere, it began to break apart, and the fragments fell together. This fall is one of the largest meteorite showers in recent history. It is the largest observed meteorite fall in recent history, with an estimated mass of more. The Sikhote-Alin meteorite fall occured on February 12, 1947. Though large iron meteorite falls had been witnessed previously and fragments recovered, never before in recorded history had a fall of this magnitude been observed. Sikhote-Alin is an iron meteorite which fell to earth on the Sikhote-Alin Mountains in Russia in 1947. The Sikhote-Alin meteorite is classified as a coarse iron octahedrite type IIB (this type of meteorite displays a beautiful pattern known as a Widmanstatten pattern when sliced and etched). 9/16″ long and will come in the 3″ x 4″ Riker Mount with Label as ShownĪn iron meteorite fell on the Sikhote-Alin Mountains, in southeastern Russia, in 1947. The growth stress is mainly due to the lost crown (needle lost) and it did not seem to be caused due to direct damages on trunk and branches (missing of resin ducts). Tree growth stress, detected in 1947, was analysed in detail through wood microsection that confirmed the winter season (rest vegetative period) of the event. The analysis of growth anomalies has shown a sudden decrease since 1947 for 4–8 years after the meteoritic impact. This research investigated through dendrocronology n.6 Scots pine trees ( Pinus Sibirica) close to one of the main impact craters. Around the large craters the trees were torn out by the roots and laid radially to the craters at a distance of 10–20 m the more distant trees had broken tops. The meteor is believed to have weighed an astonishing. The meteor that produced these meteorites fell to the earth in 1947, and is the largest witnessed fall ever. They're named after the Sikhote-Alin Mountains in Russia where they were found. The area engulfed by the meteoritic fall was around 48 km 2, with an elliptic form and thousands of craters. Sikhote-Alin meteorites are classified as iron meteorites, as they're mostly composed of this element. This research deals with the fall of the Sikhote-Alin iron meteorite on the morning of 12 February 1947, at about 00:38 h Utrecht, in a remote area in the territory of Primorsky Krai in Eastern Siberia (46☀9′36″N, 134☃9′22″E).
