Volcano Terminology

Volcanic Places in the USA

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

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.

Mount St Helens

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.

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.

The study of volcanoes, or Volcanology includes many odd terms.

How many of these d o you know?

  • caldera
  • vesicularity
  • pahoehoe
  • rheology
  • lahar
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. Dates of most recent and most destructive eruptions.
  5. Other events associated with the recent eruptions (earthquakes, floods, mudslides, etc)

      Then, write 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
