What if Tunguska hit the earth?

The Tunguska event is the largest impact event on Earth in recorded history, though much larger impacts have occurred in prehistoric times. An explosion of this magnitude would be capable of destroying a large metropolitan area.

Why did the Tunguska event not leave a crater?

Here is what scientists think happened: Objects of a suitable size for this type of explosion collide with Earth every few hundred years on average. The explosion likely happened at an altitude of 5–10 km (15,000–30,000 feet), therefore leaving no impact crater.

What do you think caused the Tunguska explosion?

In the early morning of June 30, 1908, a massive explosion flattened entire forests in a remote region of Eastern Siberia along the Tunguska River. Khrennikov and co say the explosion was caused by an asteroid that grazed the Earth, entering the atmosphere at a shallow angle and then passing out again into space.

Was Tunguska a nuclear explosion?

1) The Tunguska explosion may have been a thermonuclear explosion in the air after the asteroid entered the atmosphere, and the nuclear explosion may have been triggered by the high temperature and high pressure caused by a rock burst of the asteroid; the rock burst is triggered by the high temperature caused by the …

How often does a Tunguska event occur?

every 100 to 1,000 years
Using the age of fossil craters of large impacts and historical accounts of small meteors, scientists extrapolated the missing data for medium-sized impacts. Based on such estimates, a Tunguska-like event happens every 100 to 1,000 years.
