Check out this incredible footage off the coast of Papua New Guinea of Mount Tavurvur blowing its top off late last month.
If you watch closely, you can even catch the shock wave ram the air above the volcano - compressing the water vapor in the sky and forming a halo-like cloud.
Speaking to the Brisbane Times, Australian tourist Phillip McNamara, who filmed the video, said it was a "spur of the moment thing" to head out and record the eruption, and when the sonic boom hit the tourist party, they "absolutely crapped themselves."
