event is considered to be the largest asteroid impact on Earth in recorded history.
But it is still possible the next Tunguska
would take us by surprise, and although we are much better at finding larger asteroids, that does us no good if we are not prepared to do something about them.
is a well-known phenomenon within the space community.
We are currently aware of less than 1% of objects comparable to the one that impacted at Tunguska
, and nobody knows when the next big one will hit.
Now the thinking is that these blasts are driven deeper down by their own momentum, an idea first put forward six years ago by Mark Boslough and David Crawford (Sandia National Laboratories) to explain the roughly 2,000 square kilometers of devastation caused by the Tunguska
impact in 1908.
Impacts as powerful as the famous Tunguska
event of 1908, which was comparable to a 10-million-ton blast, should take place every few thousand years.
It was the largest object to hit the Earth since the Tunguska
event of 1908, when an exploding comet or asteroid destroyed 2,000 square kilometers of Siberian forest.
Se trata de los tres fragmentos de un cuerpo celestial enigmatico que el 30 de junio de 1908 exploto sobre la region del rio Podkamennaya Tunguska
en Siberia causando colosales destrucciones asi como toda una serie de suposiciones y especulaciones.
This makes it the most energetic event reported since the 1908 Tunguska
meteor in Siberia.
The last time anything like the Chelyabinsk event took place was on June 30, 1908, in the area of the Tunguska
River in eastern Siberia.
He was interviewed for a Discovery Channel documentary about the Tunguska
event of 1908.
Most people with an interest in astronomy will know of the Tunguska
explosion which occurred over Siberia in 1908.
The asteroid that exploded over Russia last month was the largest object to hit Earth's atmosphere since the 1908 Tunguska
event when an asteroid or comet exploded over Siberia, leveling 80 million trees over more than 830 sq miles (2,150 sq km).
8221; However it is the largest reported meteor since 1908, when an estimated 100-meter (330-foot) meteor - the largest in recorded history - exploded near the Tunguska
River in what is now Krasnoyarsk Krai, Russia.
blast, attributed to a comet or asteroid fragment, is generally estimated to have been about 10 megatons.
