Description
Option #1: Having a Blast with Active Volcanoes
Choose an active volcano from somewhere on Earth, from this online list (Links to an external site.). In a well-crafted essay, cover all of the questions below. (Tip: Investigate your volcano online a bit before committing to it for this assignment; make sure there is sufficient information available about it, in English, for you to be able to meet the paper length requirement.)
- What is the name of your volcano? How did it get that name?
- Where on Earth is it located? (If possible, include a map.)
- What kind of volcano is it?
- How old is it? (if known)
- What is its tectonic setting? Is it near a plate boundary? If so, which boundary, and how are the plates moving relative to each other?
- When have its major eruptions taken place? What happened during those eruptions?
- What kinds of rock has the volcano produced?
- What is the likelihood this volcano will erupt again in our lifetimes? How dangerous might these future eruptions be?
- Include at least one photograph of your volcano. Be sure to use APA format to document its source.
- Share any other fascinating facts you have learned about your volcano.
Your paper should meet the following requirements:
- 2-3 pages in length (not counting title page, reference page, and visuals)
- 3-4 credible outside sources
- Formatted according to the CSU Global Writing Center (Links to an external site.)

Mount St. Helens, one of the many still active of its kind, is located in the Cascade Range,
Southwest of Washington, USA. This volcano got its name after the British Ambassador, by
an English navigator named George Vancouver (Britannica, 2020). Its specific location is at a
latitude of 46.2° North and 122.18° West, with an elevation of around 8,330 feet (roughly 2,539
meters). According to geologists, Mount St. Helens belongs to the Stratovolcano class or
composite volcano. By definition, the latter are symmetrical in shape, made up of ash, lava
flows, and much other volcanic debris. Also, those volcanoes tend to be steep-sided. One key
feature of composite volcanoes is their tendency to erupt explosively, leading to considerable
damage to life and property simultaneously (Usgs.gov, 2021). Geologists believe that Mount
St. Helens began growing way before the last Ice age, which occurred 10,000 years ago. The
most ancient ash deposits found by geologists date up to 40,000 years ago. However, its cone
became visible only around 2,200 years ago, making it the youngest among the other major
and far more dangerous Cascade volcanoes; Mount Rainer and Mount Adams (Usgs.gov,
2021).
Mount St. Helens lays on the Juan de Fuca tectonic plate. This plate i...
