Jon Gustafsson, the same guy who shot amazing video last year of Iceland's Eyjafjallajokull volcano, is back behind the lens for the country's latest eruption. And this time, he's got lighting. 

The Grimsvotn volcano began erupting Saturday at 5:30 p.m. local time on May 21, sending an ash cloud 12 miles into the sky. To give you an idea of scale, more ash was released in the first 48 hours of the eruption (an estimated 120 million tons) than the Eyjafjallajokull volcano released during its entire 2010 eruption. 

Gustafsson, a writer, producer, and director, posted dramatic video via helicopter of Grimsvotn the day the eruption started, capturing what could easily pass for Mount Doom in the "Lord of the Rings" film series. He was only five miles away from the crater. 

"Once we got off the ground again we had to stay low because there were so many lightnings all around the eruption," he wrote on Vimeo. "Getting hit by a lightning in that strong wind, extreme frost and next to a live volcano was not desirable. We made it back to Reykjavik at 2 a.m. Now the airspace has been closed in a 20 nautical miles radius because of ash."
