over three feet of mud was left behind. The mudflows not only destroyed all the trees and plants, but also killed thousands of animals including deer, elk and beers. Different sources say that 57 or 62 people were killed form the eruption of MSH including the volcanologist David Johnston, a member of the U.S. Geological Survey team at MSH. The lateral blasts, avalanche, mudflows and flooding caused huge amounts of damage to the land and city. All buildings and structures in the area of Spirit Lake were buried. More than 200 houses were destroyed, leaving many people homeless. Tens of thousands of acres of forest, recreational areas, bridges, roads and trails were destroyed. Wildlife suffered huge losses. The Washington state Department of Game estimated that 7,000 big game animals (beer, elk and deer) died in the area, as did all birds and small mammals. Volcanoes can be very destructive but in the long run they are helpful. Because the ash s rich in potassium and phosphorus it helps to grow very healthy plants and crops. Volcanic heat energizes most of the world's thermal areas and hot springs. Volcanoes are also responsible for creating much of the mineral wealth on earth. The hot water underground removes minerals from the magma dn deposits them in the earth's crust. They form veins of silver, gold, zinc, copper and lead. Because of the plate movements, some minerals that were deposited on ancient sea floors are now accessible to mining. Diamonds are also created by volcanic activity and are fund in eroded volcanic pipes or tubes. The May 18 eruption wiped out most large forms of life on the north side of the mountain. Life began to reemerge in the form of bacteria, fungi, weeds, seeds, insects, spiders and pocket gophers. Bt the end of summer 1981, life was returning to the volcano. Volcanic eruptions are important to life on Earth because they add gasses to the atmosphere and water to the ocean. Volcanoes also build land mass. Flo...
