The explosion happened over the sparsely populated northern forestland above the Podkamennaya Tunguska River in what is present-day Krasnoyarsk Krai. The blast released enough energy to kill reindeer and flatten an estimated 80 million trees over an area of 830 square miles (2,150 square km).

What do we know about the Tunguska event?

Tunguska event, enormous explosion that is estimated to have occurred at 7:14 am plus or minus one minute on June 30, 1908, at an altitude of 5–10 km (15,000–30,000 feet), flattening some 2,000 square km (500,000 acres) and charring more than 100 square km of pine forest near the Podkamennaya Tunguska River in central …

How powerful was the Tunguska event?

Was the Tunguska event a natural disaster?

It is classified as an impact event, even though no impact crater has been found; the object is thought to have disintegrated at an altitude of 5 to 10 kilometres (3 to 6 miles) rather than to have hit the surface of the Earth.

Do meteors explode before impact?

“If the air can move through the passages in the meteorite, it can easily get inside and blow off pieces.” Researchers knew that meteoroids often blew up before they reached the Earth’s surface, but they didn’t know why.
