Papua New Guinea's Mount Tavurvur erupted on August 29, causing subsequent eruptions to occur in the days that followed. One such eruption was captured by Linda and Phil McNamara, a couple on vacation from Queensland, Australia. It is insane.
In the video, you can hear Phil say, wisely, "watch out for the shock—it's comin'." (And then you can hear someone say, wisely, after the shock comes, "oh, jeeze!")
"It was a spur of the moment thing to head out and film the volcano. ... We saw it erupting and the ladies from Kokopo Beach Bungalows where we were staying said they could take us out on the boat to get a closer look. I thought I might as well try and capture something you rarely get to see."
Good thinking, Phil.
