Lightning and special peat bog phenomena on Andøya,northern Norway
In 1982 a c .5 m 2 slab of peat, c .25 cm thick, was discovered on a peat bog on the island of Andøya in northern Norway. The peat slab, which weighed c .1 ton, was found 4 m to 5 m from a hole having precisely the same shape. Investigations on Andøya to date have provided information on six quite similar phenomena with slab weights varying between 100 kg and 4 tons. Outside Andøya, five similar phenomena have been recorded in Norway, and pieces of earth displaced from their original locations have been reported in Britain, Germany and the United States. Lightning is hypothesized to have caused these phenomena.
