Steam devil. The steam comes from lava entering the ocean at the Big Island of Hawaii.

A steam devil is the term used to describe a rotating updraft that involves steam or smoke. Steam devils usually occur above power plants and above freshly compacted asphalt that has been sprayed down with water in the cooling process. They rarely occur elsewhere, though they may occur in deserts or other dry and arid locations. Hot springs may also be a suitable area for a steam devil to form. Cold air steam devils have also been reported, notably with subzero temperatures over non-frozen parts of the Great Lakes.
