One of the greatest natural catastrophes the world will
ever see could be little more than a decade away. The film
Super volcano traces the evolution of an enormous
volcanic eruption, one that not only wipes out several
states of America but that threatens the entire planet. But
is such an eruption really possible? Well, super volcanoes
certainly aren't fiction. They're a normal part of the way
the Earth works and occur perhaps every 50,000 years.
Every statistic associated with a super-eruption is always
wildly over-exaggerated. Molten magma is blasted out at a
rate 140 times greater than the flow of water over the
Victoria Falls. Ash and gas are thrown more than 50km
upwards to the edge of space before falling over one
percent of the Earth's surface. Enough ash would pile up
on the ground to bury Britain under a blanket 4m thick.
Further, devastating winds carrying burning gas and red
hot ash would scour the land surface over an area of
10,000 square kilometers. Worst of all, a super-eruption is
foIIowed by a dramatic fall in global temperatures, leading
to years and years of bitter cold known as a volcanic
winter.
