We had snow for a duration of a good period of time...However; the snow melted at an unnatural accelerated rate... in a natural un heated environment, the snow would have been on the ground for a much longer duration and melted at a slower rate then today's' standard...due to car exhaust fumes' and house hold heating appliances'...to avoid such sudden Earthquakes' the best application, would be to return to heat related objects' at a slower periodic rate then what you have done, during the end of this particular snowy period.
