In earlier times local people considered that these lights are some evil spirits, devils. There are known cases of offerings to Paasselka devils up to early 20th century. Nowadays several tourist companies have included "watching of Paasselkä Devil" in their tours, as additional attraction to the usual fishing tours. From time to time tourist groups report about sightings of this phenomenon, there are taken images and videos.
Convincing explanation to this phenomenon has not been found. There are attempts to explain these lights - like the old and multiple times disproved theory about some easily ignited gases (methane) rising from the sediments of lake or some rare piezoelectric effects.
