Introduction

A volcano is a location where magma, or hot melted rock from within a planet, reaches the surface. It may happen violently, in a massive supersonic explosion, or more quietly, as a sticky, slow lava flow.

Volcanoes have been a part of earth's history long before humans. Compare the history of human beings, a few million years in the making, to that of the Earth, over four billion years in the making.

Volumes of Some Well-Known Volcanic Eruptions

  Eruption                      Date           Volume in km^3
  --------                      ----           --------------
  Paricutin, Mexico             1943                 1.3
  Mt. Vesuvius, Italy           79 A.D.               3
  Mount St. Helen, Washington   1980                  4
  Krakatoa, Indonesia           1883                 18
  Long Valley, California     pre-historic       >450 & <700
  Yellowstone, Wyoming        pre-historic           2400

Volcano Terminology

The study of volcanoes, or Volcanology, includes many odd terms. How many of these do you know? The term nuée ardente, or "glowing cloud" was first used by La Croix (1904) in his description of the volcanic flows he observed in the 1902 eruption of Mt Pelée, a historically active volcano on the island of Martinique.

Volcanic Places in the USA

Listed below are two places in the United States that are considered "active" volcanic areas.

Mount St Helens

On May 18, 1980, after a long period of rest, this quiet mountain in Washington provided detailed observations on the mechanics of highly explosive eruptions.

Long Valley

This field seismometer measures earthquakes associated with subsurface volcanic forces and may help to predict future events. It sits on a plateau known as the "Volcanic Tableland" formed by a major eruption 600,000 years ago.

Volcanic Places on Mars

Mars has its fair share of volcanic landforms, including the largest known volcano in the solar system, Olympus Mons

Research Project

Your mission is to find information and report on a volcano, other than the ones listed above, that has erupted in the last 100 years. Your reports must include:
  1. Type of volcano
  2. Geographic location
  3. Name, distance, and population of nearest major city
  4. Date of most recent eruption and date of most destructive eruption
  5. Other events associated with the last eruption (earthquakes, floods, mudslides, etc)

Then, attach a one page description on the major hazards to humans in the vicinity of this volcano. Speculate on what you would do if you were in charge of minimizing the risk to the population.
