63. How many explosions are there every year on the Moon? (A K2S Question)

From The Space Library

Technically an explosion is a sudden release of mechanical, chemical or nuclear energy. http://www.answers.com/topic/explosion (See CDROM) While they were functioning, the Apollo seismographs recorded hundreds of small meteor impacts over the course of the year on the Moon's surface. The mechanical energy released by some of these small meteors impacting the Moon might have been observed as very small explosions, say the size of a small fire cracker, if an astronaut was in the right place to observe them. Because the Moon has no atmosphere, there are no natural chemical explosions on the Moon. Nuclear explosions require a very complicated sequence of events to trigger them, events which are also not found naturally on the Moon.
