Washington: A geologist has explained the mystery of the Loch Ness monster appearing with Earth tremors and swirling bubbles from the Scottish lake of the same name.
According to Scientific American, Italian geologist Luigi Piccardi has credited the Great Glen fault system for reported sightings of the legendary beast, Fox News reported.
Piccardi said in an interview that was published in the Italian newspaper La Repubblica said that there are various effects on the surface of the water, which could be related to the activity of the fault.
He also claimed that the sightings of the Loch Ness monster have coincided with the periods of seismic activity.
Piccardi asserted that that this was a period [1920-1930], which had increased activity of the fault and what people saw were the effects of the earthquakes on the water.
The Great Glen fault is more than 100 kilometers long and divides the Scottish Highlands into northern and southern halves.
The strike-slip fault, where rocks slide past one another with no vertical movement, is largely responsible for creating Loch Ness, which is the deepest freshwater lake in Britain.
The Loch Ness monster first leapt into fame in the 1930s, when an image taken by London surgeon Kenneth Wilson that showed a serpentine head and neck was widely published, however, decades later that image was found to be a hoax.
