The explosion was powerful enough to be heard hundreds of miles away. The area around the Stony Tunguska River is inaccessible and consists mostly of bogs and pine forests. The seismic shocks from the explosion were detected around the Earth. The London Times of July 4th, 1908 reported “The remarkable ruddy glows which have been seen on many nights lately…seen…as far as Berlin.” When an expedition eventually reached the epicentre of the explosion they found that the pine trees had been pushed over, pointing away from the centre. The trees directly under the explosion remained standing. Some small craters were observed at the time but have disappeared over the years due to the boggy land. The pattern is now recognised as being similar to that produced by an air-burst nuclear bomb. Currently the event is usually explained as a small, unnoticed,
