Mount St. Helens is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States. It is 96 miles south of Seattle and 50 miles northeast of Portland, Oregon. The eruption was the only significant one to occur in the contiguous 48 U.S. states since the 1915 eruption of California's Lassen Peak. That eruption disrupted the lives of thousands and changed more than 200 square miles of rich forest into a grey, lifeless landscape. The eruption was triggered by a 5.1 earthquake centered beneath the mountain.
the most recent volcanic eruption in the u.s. was the eruption of mnt.st helens on may 18th 1980 it was on a Sunday morning in Vancouver,Washington at about 8:32 mnt.st helens erupted it destroyed forests it killed every animal in its path near the volcano it many people lost there lives and mnt.st helens blew its top the right side was completely torn off.
It was triggered by an earthquake measuring 5.1 on the Richter scale, caused an eruption, reducing the elevation of the mountain's summit from 9,677 ft (2,950 m) to 8,365 ft (2,550 m) and replacing it with a 1 mile (1.6 km) wide horseshoe-shaped crater. The earthquake was caused by a sudden surge of magma from the Earth's mantle. The debris avalanche was up to 0.7 cubic miles (2.9 km3) in volume.
people in 1915 thought that he was crazy, and back theen they didn't have the technology to support Wegner's idea.
