In this Lesson...
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.
The study of volcanos, or Volcanology, includes many odd terms.
How many of these do you know?
- caldera
- vesicularity
- pahoehoe
- rheology
- lahar
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 mechanincs of the highly explosive eruptions.
Long Valley
Mars has its fair share of volcanic landforms,
inculded the largest known volcano in the solar system,
Olympus Mons
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
- Type of volcano
- Geographic location
- Name, distance, and population of nearest major city
- Dates of most recent and most destructive eruptions.
- Other events associated with the recent eruptions
(earthquakes, floods, mudslides, etc)
References
A volcano is a location where magma,
or hot melted rock from within the planet,
reaches the surface. It may happen violently,
in a massive supersonic explosion, or more quietly, as a sticky, slow lava flow.
Volcanos 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.
