GLG101 - Intro to Physical Geology; Approximately 2 50-minute lecture periods.

What kinds of activities and strategies do you use to address volcanic hazards?

Identification of volcanic structural features using the application of composition and viscosity. For example, the students examine a slide showing features of a shield volcano and then describe the size, shape, rock color, and how explosive the volcano appears to be. They must then hypothesize what the volcano's igneous composition is (mafic) and how viscous the magma was to produce this type of eruption/structure (low viscosity).

Provide URL or citation for books, articles, videos, or websites you find useful to teach about volcanic hazards.

I utilize "Understanding Volcanic Hazards" by IAVCEI and a worksheet/grid that I have the students fill out while watching the video.]]> Pamela Nelson 1328564580 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18481 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18489 Rachel Beane 1328805120 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18489 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18490
I introduce the students to magma chemistry and differences in viscosity due to silica content. I use the analogy of hot and cold maple syrup to explain viscosity. I then post images of different types of volcanoes and ask the students to tell me eruptive styles and what evidence is in the image to determine the various eruptive styles.]]> John Harris 1328822040 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18490 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18491
I use a variety of images and multimedia, including videos and clips of real-world volcanic phenomena in addition to a number of analogue demonstrations to demonstrate and teach about volcanic processes.

I also utilize "Understanding Volcanic Hazards" by IAVCEI, in addition to the NOVA special "In the path of a killer volcano"]]> Geoffrey Cook 1328845620 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18491 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18492
I introduce students to volcanoes by using corn syrup and lava to demonstrate the properties of different types of lavas. I also spend a day talking about the Yellowstone supervolcano to spike their interest. ]]> Alyssa Chaplin 1328888820 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18492 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18494
About 2 weeks. Volcanoes and tsunami always the favorite for the students.]]> Susan McGeary 1328892180 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18494 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18495
This is the class I teach about geologic hazards, specific to the Pacific Northwest. I devote 3-4 weeks on volcanoes.

Our college is about 15 miles south of the Seattle area. We draw students from King and Pierce County. Many of these students live within the lahar hazard zones of Mt. Rainier. Those that don't would still be affected by a major eruption of this volcano -- they work, have family, play, etc in the lahar hazard zones.

My students evaulate and write about their risk from volcanic eruptions. We use the Volcanic Hazards Maps for all five of Washington's potentially active volcanoes!]]> Carla Whittington 1328893320 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18495 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18496 Kati Szramek 1328896860 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18496 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18497

We are using activities developed at an NAGT-USGS sponsored workshop run by Mike Poland. Many of the activities are posted on the SERC webpages.]]> Eric Christiansen 1328897820 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18497 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18498
I try to use a few video clips when time allows. I almost always show them where to find links to webcams of active volcanoes on the USGS website and we look at them periodically, hoping to catch one "doing something."]]> Polly Bouker 1328901060 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18498 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18502 george buchanan 1328901840 http://serc.carleton.edu/NAGTWorkshops/hazards/discussions/60605.html#post18502
