PBS Digital Studios recently began a new YouTube series called UnderH2O, kicking it off with footage of an erupting underwater volcano.

Off the coast of Hawaii, a team of divers with camera equipment swam down to film where lava was flowing from the Kilauea crater.

As new lava emerges, it quickly cools, forming billowy, round shapes called pillow lava,” PBS explained. “The constant accumulation of new rock results in frequent collapse and avalanche on the reef slope — an accelerated cycle of creation and destruction that makes for a very unstable environment.”

Check it out (Note: Actual footage of the erupting underwater volcano comes into play around 2:30 and there is a bit of strong language when the divers surface and describe their experience at the end):

When the diver surfaces, he calls it “the most intense thing I’ve ever done in my life.”

“As we decided to come up, the entire earth is rumbling at a frequency that makes your whole body vibrate. It feels like the entire side of the mountain is going to explode,” the diver said.

The UnderH2O series will not only provide cool, below the surface footage but will delve into how cameramen are able to capture such scenes.
