Volcano Monitoring with GPS: Westdahl Volcano Alaska
Maite Agopian, EarthScope; Beth Pratt-Sitaula, EarthScope
Learners use graphs of GPS position data to determine how the shape of Westdahl Volcano, Alaska is changing. If the flanks of a volcano swell or recede, it is a potential indication of magma movement and changing ...

Measure a Changing Volcano
EarthScope Consortium
This hands-on demonstration illustrates how GPS can be used to measure the inflation and deflation of a volcano. Volcanoes may inflate when magma rises closer to the surface and deflate when the pressure dissipates or after an eruption.

Taking the Pulse of Yellowstone's "Breathing" Volcano
Beth Pratt-Sitaula, EarthScope; Shelley E Olds, EarthScope Consortium
In this activity, students learn about volcanism in Yellowstone National Park, focusing on its history of eruptions, recent seismicity, hydrothermal events, and ground deformation. They learn how scientists monitor ...

Earthquake/Volcano Guided Research Project
Brett Dooley, Patrick Henry Community College
Students work collaboratively in triads to understand events associated with an historic earthquake, an historic volcanic eruption, and current techniques for monitoring one of the two natural disasters. After ...

Threat of Flank Collapse at Kilauea Volcano, Hawaii: Case Example
Barb Tewksbury, Hamilton College
Students evaluate fault and earthquake data plus focal mechanism solutions, and develop a picture of on-going deformation of the south flank of Kilauea Volcano that might one day transition to catastrophic flank ...

ConcepTest: Order of Volcano Formation
Examine the diagram below. The lettered objects represent volcanoes formed on an oceanic plate above a hot spot. The arrow illustrates the direction of plate motion. In what order did the volcanoes form (youngest ...

ConcepTest: Movement of Volcano
A volcano formed over a hot spot in the Pacific Ocean would travel approximately _______ in 1000 years. (Assume a constant rate of plate motion. 1 km = 1000 m; 1 m = 100 cm; 1 cm = 10 mm.) a. 1-2 meters b. 100-200 ...

Measuring earthquake and volcano activity from space
SHIMON WDOWINSKI, Florida International University
This tutorial is based on real InSAR observations acquired over the Andes from 1992 to 2005. It will get the student acquainted with InSAR observations and basic concepts of space geodesy.
