    On the morning of 30 June 1908, a large explosion occurred near the Podkamennaya Tunguska River in Yeniseysk Governorate (now Krasnoyarsk Krai), Russia. That event is known as the Tunguska event that leveled trees across more than 2,000 square kilometers. It is classified as an impact event, even though no impact crater has been found. Due to the remoteness of the site and the limited instrumentation available at the time of the event, modern scientific interpretations of its cause and magnitude have relied chiefly on damage assessments, and geological studies conducted many years after the fact. The most likely cause...

    At 7.17am on June 30, 1908, an explosion like a hydrogen bomb erupted in Siberia - and until now, scientists have offered no conclusive explanation for the event.The Tunguska event occurred near the Tunguska River in SiberiaItalian scientists claim to have found chunks of a meteorite in nearby Lake Cheko Seismic reflection and magnetic data revealed an anomaly close to the lake center, about 30ft below the lake floor compatible with the presence of a buried stony object and supports the impact crater origin for Lake Cheko.' 'The sky split in two and fire appeared high and wide over the...

    Explanation: Yes, but can your meteor do this? The most powerful natural explosion in recent Earth history occurred on 1908 June 30 when a meteor exploded above the Tunguska River in Siberia, Russia. Detonating with an estimated power 1,000 times greater than the atomic bomb dropped over Hiroshima, the Tunguska event leveled trees over 40 kilometers away and shook the ground in a tremendous earthquake. Eyewitness reports are astounding. The above picture was taken by a Russian expedition to the Tunguska site almost 20 years after the event, finding trees littering the ground like toothpicks. Estimates of the meteor's size...

    Crater From 1908 Russian Space Impact Found, Team Says Maria Cristina Valsecchi in Rome, Italy for National Geographic NewsNovember 7, 2007 Almost a century after a mysterious explosion in Russia flattened a huge swath of Siberian forest, scientists have found what they believe is a crater made by the cosmic object that made the blast. The crater was discovered under a lake near the Podkamennaya Tunguska River in western Siberia, where the cataclysm, known as the Tunguska event, took place (see map). On June 30, 1908, a ball of fire exploded about 6 miles (10 kilometers) above the ground in...

    In late June of 1908, a fireball exploded above the remote Russian forests of Tunguska, Siberia, flattening more than 800 square miles of trees. Researchers think a meteor was responsible for the devastation, but neither its fragments nor any impact craters have been discovered. Astronomers have been left to guess whether the object was an asteroid or a comet, and figuring out what it was would allow better modeling of potential future calamities. Italian researchers now think they've found a smoking gun: The 164-foot-deep Lake Cheko, located just 5 miles northwest of the epicenter of destruction. "When we looked at...

    The so-called ‘Tunguska Event’ refers to a major explosion that occurred on 30 June 1908 in the Tunguska region of Siberia, causing the destruction of over 2000 km2 of taiga, globally detected pressure and seismic waves, and bright luminescence in the night skies of Europe and Central Asia, combined with other unusual phenomena. The ‘Tunguska Event’ may be related to the impact with the Earth of a cosmic body that exploded about 5–10 km above ground, releasing in the atmosphere 10–15 Mton of energy. Fragments of the impacting body have never been found, and its nature (comet or asteroid) is...
