Tunguska was not a nuclear explosion. It was an explosion (An air burst explosion at that) most widely thought to have been caused be a asteroid; but no it was not a NUCLEAR explosion
An air burst is the detonation of an explosive device such as an anti-personnel artillery shell or a nuclear weapon in the air instead of on contact with the ground or target or a delayed armor piercing explosion. Aerial bursts may also arise from the explosion, above the ground, of incoming self-detonating meteoroids as some postulate happened in the Tunguska event
