" 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 monster " Nessie " 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...
