VOLCANO DESTROYS ITSELF IN VIOLENT ERUPTION.
After lying dormant for 123 years the build-up of pressure causes Mt St Helens to erupt violently.
At least 57 people have died after the massive eruption of Mount St Helens volcano in Washington State, USA. Many more are missing and the death toll is expected to rise.
A huge cloud of ash has turned day into night for towns and cities across north-western America. People have been told to stay indoors and wear gauze masks. Many roads have been closed, trains halted and aircraft grounded.
Mount St Helens exploded at 08:32 local time on 18 May 1980. The eruption took place after a series of earthquakes in Washington. The eruption was extremely violent, and though no lava ran the ash clouds caused the city to go dark. The eruption was so violent that the volcano was dramatically reduced in size. Mount St. Helens is a volcanic mountain in the Cascade Range in Western North America, in the state of Washington. The Juan de Fuca plate went under the North American plate and melted into material in the mantle which I shot and sticky. This is called a destructive plate boundary. This material then comes up through the volcano, and solidifies, making a cone shaped volcano. The vent often blocks itself up with residue magma, so the magma builds up until the volcano can’t withstand the pressure. Eruptions are violent. Mt St Helens exploded sideways. The eruption caused a massive debris avalanche, reducing the elevation of the mountain's summit from 9,677 feet (2,950 m) to 8,365 feet (2,550 m).
Primary effects
The short term effects include hot ash and gas destroying forests and logging camps.63 people died, mainly by poisonous gases. Lahars (mudflows of ash and water) covered
an extensive area surrounding the volcano reaching up to 12miles away from the volcano. The eruption killed 57 people, in the lateral blast, ash fall, and lahars. The causes to death included asphyxiation, thermal injuries, and trauma. Four indirect
