Abstract
ON the morning of June 30, 1908 a meteor caused great damage in the region of the isolated trading station Vanovara in Siberia, Russia. Investigations of this meteor, called the Tunguska Meteor, have been described by Krinov1. Light from the meteor was visible even in a sunlit, cloudless sky. There was an explosive wave, with an energy between 3 and 5 × 1023 erg2, blowing down trees over an area of approximately 2,000 km2. Thermal energy, estimated to be between 1 and 2 × 1023 erg, caused fires and seared trees up to 18 km from the centre of the blast. But it appears as though the meteor never reached the ground, for no crater was formed, nor have any fragments been found which can be positively identified as part of the meteor.
