• Footage released by the US Geological Survey (USGS) on Tuesday showed the volnado spinning in front of magma fountains.
• This unusual weather phenomenon forms when extreme volcanic heat mixes with cooler air, creating a swirling blend of dust, pumice, and ash.
• Hawaii’s Kilauea has been erupting lava from its summit crater approximately weekly since last December, attracting tourists to the site.
