  • Explosions, Deflagrations, and Detonations - NFPA
    A detonation is an explosion where the flame speed is greater than the speed of sound Detonations are louder and often more destructive than deflagrations While deflagration occurs when a fuel and oxidizer (typically air) mix, a detonation doesn’t always need an external oxidizer
