Explosion is the basic classlabel for explosion ODFs (note however that if you set an ODF's classlabel to Explosion, the ODF will crash the game). The commands available for the Explosion classlabel are inherited by all explosions that are subclasses of an explosion. For instance, ShockwaveCannon has all the commands that ShockwaveExplosion has.
Explosions are used by some Weapon, Ordnance, and GameObject classlabels to create area of effect results.
