Helens is located in the Northern Hemisphere in the continent of North America. It is in the mountain range the Rockies. It is located on a destructive plate boundary.
The Juan de Fuca plate oceanic crust moves eastwards towards the North American Plate continental crustand is forced downwards.
This movement creates friction which produces earthquakes and due to an increase in temperature destroys the oceanic crust.
The Plate Boundaries It triggered an earthquake measuring 5. The landslide was meters thick in the upper Toutle valleys.
At the same time, a giant cloud of ash rose 15 miles 24km into the sky in just 15 minutes. Then hot ash, pumice and gas known as pyroclastic flows poured out of the crater.
The heat melted the snow, which created mudflows in all the major river valleys. When it erupted, it permanently changed the surrounding landscape. Westerly winds bowed millions of tons of ash across the United States turning blue skies grey as far as Spokane, Washington - miles km away.
Helens erupted the volcano went through 3 months of seismic activity as magma rose within the mountain. As the magma rose, a large bulge grew on the north flank of the volcano.
This was due to a blockage in the main vent resulting in the growth of a crypto dome mound of viscous lava in the side of the volcano. There was also an earthquake in March measuring 4.
US Geological survey team monitored at different camps called Coldwater 1, Coldwater 2 and Swift creek and the most expensive equipment was used. On the 28th March 14 residents had to be evacuated from their homes because of how close they were to the volcano. Harry Truman an elderly local resident refused to leave his home because he believed Mount St.
Helens was apart of him because he grew up there, he later died in the blast. Also on the 28th march police closed up roads and 2 days later Red Zones were set up miles from the volcanoes summit. People were also warned via television broadcasts from 3rd April onwards, reporters were air lifted to the volcano.

Helens had forests of cedar and fur. It was the last untouched forest in the United States and the eruption blew and buried nearly square miles of forest. The eruption lasted 9 hours but Mount St.
Helens and he surrounding landscape where automatically changed within seconds.
Around 57 people were killed mainly by poisonous gasses. A resident called Harry Truman and a photographer also died. Buildings, property and farmland were damaged and destroyed. Ash raced down Mount St. Helens at miles per hour destroying communication signals, transport, electricity and telephone lines.Mount St.
