In 1998, a meteorite, approximately 2.5 millimeters (1 ⁄ 8 in) across, was described from a deep sea sediment core from the North Pacific, from a sediment sequence spanning the Cretaceous–Paleogene boundary (when the site was located in the central Pacific), with the meteorite being found at the base of the K-Pg boundary iridium anomaly ...
It was an 3–5 megaton explosion that occurred near the Podkamennaya Tunguska River in Yeniseysk Governorate (now Krasnoyarsk Krai), Russia, on the morning of 30 June 1908. The explosion over the sparsely populated East Siberian taiga flattened an estimated 80 million trees over an area of 2,150 km 2 (830 sq mi) of forest, and eyewitness ...
More than a century ago, something exploded in the sky above Siberia, breaking windows and creating a shining ball of light – but was it a meteor impact? Strange new theory of what caused ...
The Kamchatka superbolide is estimated to have had a mass of roughly 1600 tons, and a diameter of 9 to 14 meters depending on its density, making it the third largest asteroid to impact Earth since 1900, after the Chelyabinsk meteor and the Tunguska event. The fireball exploded in an airburst 25.6 kilometres (15.9 mi) above Earth's surface.
Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2]
The most powerful meteor air burst in the modern era was the 1908 Tunguska event. During this event a stony meteoroid about 50–60 m (160–200 ft) in size [ 1 ] [ 2 ] : p. 178 exploded at an altitude of 5–10 km (16,000–33,000 ft) over a sparsely populated forest in Siberia .
For comparison, the 1908 Tunguska event was caused by an object about 60–190 m (200–620 ft) in size, while the 2013 Chelyabinsk meteor, which injured thousands of people and damaged buildings when it generated a large airburst over Russia, was estimated to be just 20 m (66 ft) across.
