I think something similar to this happened in the 1815 Tambora eruption.Now even though these definitely are not true tornadoes by any means, a very interesting type of volcanic vortex is pyroclastic surge vortices. These have been only studied once, during the 1951 Mt Lamington eruption. They seem to be generated by extreme turbulence within the surge and travel outwards creating streaks of intense damage. These vortices were likely responsible for unusually intense damage within a village downstream of the volcano. Here buildings were completely swept away with debris being scattered for a wide area, a steel-framed hospital was leveled and a car was lofted into the top of a tree.
