Blundering into the blast zone

Forty years ago yesterday (May 13, 1980) as Dick Waitt records in his 2014 work In the Path of Destruction, the Washington State Department of Emergency Management and other agencies including the U.S. Geological Survey were forced by public pressure to open up large portions of the forest lands around the then-unquiet Mount Saint Helens volcano that had been off-limits since the end of April.

(then-Governor Dixy Lee Ray had signed an order establishing a "red zone" around the volcano on 30 APR 1980 that turned out to be, in fact, grossly undersized - something like 50 of the 55 to 60 people who died in the eruption on 18 MAY were outside the original "red zone" - see below).

But that wasn't enough for the people who made their living in the woods, or who had cabins or houses near the volcano, or who just wanted to go back into the forest to mine or pick mushrooms or whatever.

Saturday, 17 MAY, something like 50 vehicles drove into the area that had been closed to bag up their stuff. The eruption took place at 8:32am, before the second planned caravan enetred the blast zone at ten, and since it was a Sunday the active logging tracts were empty.

Still, somewhere in the vicinity of 55 people were killed.

That ain't Pompeii...but, then, we knew more than they did back in the First Century, and knew how damn deadly dangerous these stratovolcanoes were. The volcanoligists of what eventually became Cascades Volcanoes Observatory warned the State of Washington that this monster could do all sorts of unpredictably deadly things. And the state government listened...until people grew bored and restless and demanded to "reopen" the woodlands around an actively erupting volcano. We learned a hard lesson about the power of convergent margin tectonics and nature in general.

As a geologist I find it kind of interesting to reflect on that, just at the moment.

Why?

Oh...y'know. No reason.

Just a thought.
