Volcano 'Tornado' Spotted During Iceland Eruption
Yeah. Apparently this is a thing.
The video above:
A infrared camera from the Nicarnica Aviation's NicAIR II was used to spot the toxic tornado on Sept. 3, 2014. It whirled volcanic gases and ash particles during an ongoing Holuhraun fissure eruption.

The toxic tornadoes were spotted in a poisonous cloud of sulfur dioxide gas spewing from Iceland's Holuhraun lava flow on Sept. 3. One narrow, swirling column stretched 3,300 feet (about 1 kilometer) into the air. A remotely monitored infrared camera caught the dramatic whirlwinds on video.
"We haven't seen anything like this before," said Fred Prata, chief technology officer at Nicarnica Aviation in Kjeller, Norway, the inventor of the infrared camera used for the images. "I was quite surprised to see it."
Nicarnica's infrared camera can track ash clouds from planes, but is now undergoing a ground-based test run in Iceland through the FutureVolc project, an international collaboration to monitor Europe's natural hazards.
