Mount St. Helens
As the chance of a new eruption at Mount St. Helens increases today, Shelley Powers has posted her recollection of living downwind of the previous eruption on May 18th 1980. Makes interesting reading – and makes you wonder what on earth it will be like if Yellowstone Park erupts (the last eruption there was 3000 times the power of the 1980 Mount St. Helens eruption).
