The Earth-shattering Loch Ness Monster that wasn’t

I have plenty of theories.
Mulder, F.W. in the “The X-Files” (1993)

Summer is traditionally Silly Season, when newspapers publish strange stories about aliens and monsters again and again to bridge holiday time – and so will July on “History of Geology” be dedicated to frivolous science stories…

In 2001 the Italian geologist Luigi Piccardi presented during the Earth Systems Processes meeting in Edinburgh a hypothesis explaining the supposed appearance of the sea/lake monsterNessie” as a result of geologic forces.

According to Piccardi’s idea the historic description of the monster – appearing on the surface with great (earth)shakes and rumours – could be associated with bubbles emanating from the bottom of the Scottish lake of Loch Ness in response of seismic activity along the Great Glen fault system, passing below the lake.

In an interview published June 28 in the Italian newspaper “La Repubblica Piccardi explains:

There are various effects on the surface of the water that can be related to the activity of the fault..[] If we consider the terms used by Adamnan, the beast appears and disappears with great shakes. I think it’s an obvious description of what really happened…[] We know that this was a period [1920-1930, a period characterized by many reported sightings of Nessie] with increased activity of the fault, in reality people have seen the effects of the earthquakes on the water.

According to the biography by Adamnan of Saint Columba (“Vita Sancti Columbae“, written in the year 690) the scene described by Piccardi happened in 565 A.D. Trying to cross the river Ness the saint is attacked by a beast – but Columba implores the protection of god and the monster promptly disappears. The original text however is very vague and gives no detailed description of the event, it states only that it was an “unknown beast” and it approached with the mouth wide open and a loud roar (Piccardi’s interview and interpretation of the historic source prompted a detailed rebuttal by Italian zoologists). The mention that the beast was of unknown origin makes it appear as unique event, so seemingly no monster tradition existed previously (and as plesiosaur, Nessie had to come to the surface to breathe and should be spotted more often).  For Adamnan obviously Nessie was much less of interest than the ability of Saint Columba to tame beasts and demons – an important qualification for early missionaries – so it is possible he added this encounter to make St. Colombian´s legend  bigger than real life.

Even if this anecdote is granted for real, the vague description doesn’t really support any proposed scenario, neither bubbles emanating from the river or a presumed lake monster. A surviving plesiosaur in Loch Ness can more reasonable be explained by a combination of hoaxes, misidentification of common animals and promotion for tourists – a long tradition of research on the lake has never delivered even a clue for the possible existence of any larger animal in the Loch.

Fig.1. Title page of Jules Verne’s 1867 edition of “Voyage au centre de la Terre” with a vignette by Edouard Riou, depicting a fierce battle between pterodactyls, a Plesiosaurus and a Mosasaurus, such images mark the first appearance of these Nessie-like creatures in popular fiction (image in public domain).

Not only biological constrains, also the geology don’t seems to support the existence of an earthshaking monster in Loch Ness.  Common earthquakes from the Loch Ness area range between magnitude 3 to 4, larger events were recorded only in 1816, 1888, 1890 and 1901. These earthquakes don’t coincide with the years of supposed increased activity of Nessie (like 1933). Even the largest Scottish earthquakes were anyway too weak to cause any observable effects on the surface of Loch Ness (curiously the great earthquake of Lisbon in 1755 generated waves on Loch Ness, but no Nessie sighting is reported for this year).

Piccardi himself sees the value of his hypothesis more in the possibility to make geologists aware of the geological origins of some myths, as to propose verifiable cryptozoology.

    Has anyone ever looked for a correlation between sightings of Nessie and the state of the local tourist industry in and around Loch Nessie? It would seem to me that this maybe one of the first verifiable well-documented instances of the “If you build it they will come” Phenomena.

    Are you kidding me? Isn’t Scientific American aware that this was exposed years back? Try Googling some images of an elephant swimming and take a look at one with only its trunk exposed. The famous image that is always posted was actually a photo of a elephant from a traveling circus who was swimming in the Loch during a rest stop. The circus was on its way either to, or from, Inverness. The circus passed by there every year with its elephants. Several years ago someone released some more photos that were taken of the elephant swimming in the loch that day. It is completely obvious once you see the actual elephant in the other pictures.

    @MandoZink I believe that one was exposed to be fake entirely, not an elephant.

    Years ago, someone posted a series of pictures of the actual elephant before, during and after it was submerged. There was no need whatsoever to fake it. They just took the photo that showed only the trunk above water and stated the Nessie hoax.

    I could not locate those particular photos online, but there are similar ones that make it obvious:

    Some propose to support the reality of an animal existing in Loch Ness that is called ‘the monster’, that many times, the monster was seen in the places were incoming rivers add its water to the lake, and that it’s in these place were the amount of fish that an animal such as the monster can eat is greater. The whole subject remains just an element for fun and beer-talk, that also brings some tourists there. Who could ask for anything more?
