Mount Rainier

Past Eruptions in this Area

• The first eruption of Mount Rainier was half a
  million years ago. Mount Rainier is a very tall
  mountain, because of this there are glaciers that
  form on it.
• The last eruption was in the 1840s.
• Unlike the Hawaiian Volcanoes, Mount Rainier
  explodes much less times, but when they do blow
  they are way worse than the Hawaiian Volcanoes.
• Mount Rainier usually blows up every 100 years.

Things that Happen when Rainier Erupts

• Projectiles out of the top (as in lava and rock)
• Tephra
• Pyroclastic flow
• Volcanic gasses
• Mudslides
• Flooding from melted glacier
• Landslides

The 1840s Eruption of Mount Rainier

• This eruption sent a lot of hot lava and debris
  fly out of his top. It melted the snow and ice on
  the volcano and caused mud slides.
• These mud slides went down the rivers and caused
  a lot of damages to homes near the bottom of the
  volcano.

Conditions of the Volcano and Population Around it

• Mount Rainier is an active volcano but it has
  been showing no signs that it is going to erupt
  any time soon.
• If/when Mount Rainier erupts they think it is
  going to be one of the worst eruptions in
  history. They think this because there are many
  big cities around Mount Rainier.
• Populations of Cities around Mount Rainier.
• Ohanapecosh- Not very many people. Only around
  100
• Ashford- 450-500 people
• Wilkeson- Unincorporated
• Greenwater- 650-675 people.

Threat of Volcanoes of cities by Mt. Rainier

• There is not a lot of risk of people dying
  because there isnt really very many people. If
  the mudslides and land slides are bad they may
  get into the bigger cities and cause a lot of
  damage.

Predictions

• I think that Mount Rainier will explode around
  2,025-2,040 because that will be a around 200
  years which it will have built up higher and then
  explode. I think it will be one of the biggest
  damage volcano in U.S. history.
