There are other, more modern, theories about the origins of the legend of the Loch Ness Monster, Nessie.
One such theory was suggested by an Italian Geologist named Luigi Piccardi.
He proposed that many of world’s mythological and supernatural events and legends have their origin in some form of natural seismic activity.
Some of the earliest reported Loch Ness Monster sightings (hundreds of years ago) stated that a sighting of the creature in the waters of the loch was followed by a terrible roar that shook the earth in the surrounding area.
According to his theory, Luigi suggests that these encounters were actually caused by earth tremors (the Great Glen is, after all, a fault line).
The waters of the Loch would have been churned up by a tremor creating shapes and reflections that could – to the superstitious – be mistaken as a living creature.
Of course, this does not account for all of the many actual “sightings” of the Loch Ness Monster itself (rather than just ripples in the water) but it could go a long way towards explaining some of the so-called encounters.
