Mount St. Helens is an 8,363-ft. tall volcanic landmark of the state of Washington. It was a popular tourist attraction and recreation area for most of the 20th century. It was also The U.S.’s 8th tallest mountain, towering at 9,977 ft. It is now the 14th tallest at 8,363 ft. tall, due to a major eruption in May of 1980. On May 18, 1980, the beautiful, peaceful well-known mountain Mount St. Helens became the most dangerous mountain in U.S. history in a matter of minutes. There are records of volcanic activity in the mountain decades before, but this eruption is by far the worst. The mountain has been active for decades, and still is to this day. There have been reports of minor eruptions in 1898, 1903, and 1932. The volcano was relatively …show more content…
on March 27, 1980, U.S. Geological Survey issued an official Hazard Watch for Mount St. Helens. On March 27, a crater had formed through its summit ice cap and had grown 1,300 feet in diameter. Four days later, instruments set up by volcanologists that used lasers placed in a mountain ridge six miles away to record change picked up volcanic tremors, which meant that magma was on the move. In April, laser equipment detected changes in the mountain’s profile- an ominous swelling bulge forming between the fissures (Mary Bagely). Laser measurements showed a bulge was that growing at about five feet per day by late April. By May 17, a total of 10,000 earthquakes shook the volcano and the north flank had grown outward at least 450 feet to form a bulge (magma had risen high in the …show more content…
Along with that, a plume of the volcano was blown 80,000 feet in air and rained down 250 miles away in Spokane. The winds blew 520 million tons of ash eastward 2,200 miles across the U.S. in seven states and caused complete darkness in Spokane, Washington, which was 250 miles from the volcano. The blast also wiped out 230 square miles of forestland. With the accumulation of airborne debris, the ash cloud encircled the globe in 15 days. In the end, along with the total land area destroyed, a total of 57 human lives were lost, along with about 7,000 big game animals and 12 million salmon fingerlings in hatcheries (Mount St. Helens – From the 1980 Eruption to 2000).
The eruption of Mount St. Helens on May 18, 1980 was the worst recorded eruption and landslide in U.S. history. Multiple minor quakes and eruptions had lead up to the major eruption that will forever remain in the minds of those who experienced it. The mountain had been downsized and lots of land was destroyed, along with people’s comfortability with the mountain. The world will never look at Mt. Saint Helens the same way ever

    Mount St. Helens, located in Skamania County Washington State, had an eruption which caused the death of fifty-seven people on May 18, 1980. A cloud full of ash rose into the sky, turned everything dark, and made any given time of day appear as black as midnight across many of the north-western states. It was recommended that people not leave their homes and they were told to wear gauze masks to keep the ash from entering their lungs. The eruption also caused about one thousand miles of roads to close (including state highways), trains to be stopped, and it forced aircraft to land. The repairs for the roads alone cost hundreds of millions of dollars.…

    Credit: Douglas LevereView full size image The Peach Springs Tuff covers parts of Arizona, Nevada and California, from Barstow, California, to Peach Springs, Arizona. Geologists use the creamy white and pink rock as a unique marker in the region. The western United States suffered at least 100 of these huge eruptions starting about 40 million years ago (a consequence of shifting tectonic plates). It 's not clear whether every one of these supervolcanic blasts sent out slowly moving ash flows, but Valentine said he sees similar evidence in other areas. The powerful Peach Springs eruption ejected 72 cubic miles (300 cubic km) of pulverized rock into the air.…
