Seismic gas Italian geologist Luigi Piccardi has proposed geological explanations for ancient legends and myths. Piccardi noted that in the earliest recorded sighting of a creature (the Life of Saint Columba), the creature's emergence was accompanied "cum ingenti fremitu" ("with loud roaring"). The Loch Ness is along the Great Glen Fault, and this could be a description of an earthquake. Many reports consist only of a large disturbance on the surface of the water; this could be a release of gas through the fault, although it may be mistaken for something swimming below the surface.
