ACTIVE VOLCANOES AND THEIR TECTONIC SETTING

Visit Volcano World, a NASA-sponsored web site at the University of North Dakota. Go to Current Eruptions (on the right-hand side of the page) to see a list of current volcanic activity around the world.

Select any volcano that has erupted in the last 4 months (since May 25, 2000) and answer the following questions:

1. What is the name of the volcano?

2. Where is it located? Please give latitude and longitude and a descriptive answer, such as "southeastern Pennsylvania" or "north-central Atlantic Ocean".

3. What kind of volcano is it? Choose from:
   • stratovolcano (or composite volcano)
   • shield volcano
   • cinder cone
   • giant caldera
   • fissure volcano
   For a review of these different types of volcanoes, visit this set of pages from NASA's "Classroom of the Future".

4. Classify the volcano according to its tectonic setting. Choose from:
   • subduction zone volcano (convergent plate boundary)
   • mid-ocean or rift volcano (divergent plate boundary)
   • hot-spot volcano (in the middle of a plate).
   For a review of these tectonic settings, visit this set of pages. To answer this question you will need to locate your volcano on a map of the world, and compare that location to nearby plate boundaries. Figure 17.13 from your text may be useful. There is also a tectonic map of the world in the lab room.

5. Finally, when did this volcano last erupt? Describe the character of that eruption, as reported.

Bring your answers to these questions with you to class on Friday, 9/29. Please include your name and lab day on your sheet.
