A newly-posted YouTube video shows the moment a volcano erupted in Papau New Guinea.
You can see the shock wave radiate out into the sky above Mount Tavurvur.
Off camera, a man can be heard saying, "Watch out for the shock, it's coming."
Approximately 13 seconds later, the shockwave hits Phil McNamara, who was filming the eruption from a boat off shore.
You can hear a man's voice say, "Holy Smoking Tolitos!"
Mount Tavurvur erupted on Aug. 29, but the video was not posted until Friday, Sept.
By Sunday afternoon, the video had already been viewed more than 3,600,000 times.
Warning for sensitive viewers: Video contains one expletive (the S-word)
