The exploding tundra: from mounds to craters
Did you know?
There are alternative theories about how the explosions occur.
A helicopter can land in some craters because they are so big.
If there is an explosion under a gas or oil pipeline, this could cause problems such as pollution.
These explosions are very small compared with the world's greatest explosion which happened in Siberia in 1908. It is called the Tungus (the name of the area) incident. It is thought that a meteorite exploded above the forest flattening all the trees in a circle from a single point.
