St. Helens released an amount of energy equivalent to 27,000 Hiroshima-sized nuclear weapons and ejected more than 1 cubic mile (4 km³) of material. A quarter of that volume was fresh lava in the form of ash, pumice, and volcanic bombs while the rest was fragmented, older rock.
The ash fall created some temporary but major problems with transportation, sewage disposal, and water treatment systems. Visibility was greatly decreased during the ash fall, closing many highways and roads.
Over a thousand commercial flights were cancelled following airport closures. Fine-grained, gritty ash caused substantial problems for internal-combustion engines and other mechanical and electrical equipment. The ash contaminated oil systems and clogged air filters, and scratched moving surfaces. Fine ash caused short circuits in electrical Transformers, which in turn caused power blackouts.
There were also indirect and intangible costs of the eruption. Unemployment in the immediate region of Mount St. Helens rose tenfold in the weeks immediately following the eruption
this meant that the tourism and the alot of shops and supermarkets were down and were either out a job and had to move somewhere else to find a job and some large buisness's had to start there companies from scratch.
A column 80,000 feet high deposited volcanic ash in 11 nearby states. At the same time, it melted snow, ice, and several entire glaciers which as volcanic mudslides reached as far as the Columbia river 50 miles away.
Fifty seven people and all wildlife died. And hundreds of square miles were reduced to wasteland.
The sound was heard 200 miles away.
The ground would be getting hotter and it would shake.
God had a steamy crap and ate it with a golden spoon after he licked his toes with a tongue full of spot puss.
