VEPP: Monitoring Pu'u O'o part of NAGT:Teaching Resources:Volcano Exploration Project: Pu`u `O`o:Examples
NOTE: This activity has NOT been attempted yet in class, and therefore still needs significant refinement. It will be updated once it has been developed further. Brief three-line description of the activity or assignment and its strengths: This is a two-part exercise. Part I is designed to train students in the technical use of the VEPP website and to train them to use observations from multiple datasets (GPS, tilt, seismic, physical behavior) to draw conclusions about the volcano's physical behavior. Part II involves a month-long monitoring exercise using real-time data from Pu'u O'o followed by interpretation of those data. Full length description: This is a two-part exercise. The main goal is to provide as realistic a volcano monitoring experience as possible given classroom constraints. Part I is designed to provide students with the ability to work with the VEPP website to generate plots of GPS, seismic, and tilt data, as well as access webcam images and make movies from them. In the process, they will be interpreting data from the July 21 2007 dike injection and eruption event and focusing on deformation concepts. Part II is an exploratory exercise, with the goal of reproducing the monitoring process a volcanologist would use for this volcano. The students are going to be responsible for monitoring the behavior of Pu'u O'o for one month. This process entails gathering data on a daily basis (all available data sources: GPS, seismic, physical observations, tilt), so as to accumulate a month-long record of the behavior of the volcano. Each week they will have to produce a report summarizing the behavior of the volcano, including plots of all measurements with time and correlations between different variables (e.g., seismic events vs horizontal movement from GPS). At the end of the month, the final report will also include calculations about changes in magma volume and comparisons to estimates of erupted volume. Students will also address several interpretive questions, including: a) how does magma storage volume (calculated from deformation data) compare with eruptive volume over the same period; b) how do the various monitoring parameters relate to each other; c) how does the behavior of Pu'u O'o during the month they observed it compare to the July 2007 behavior they analyzed in Part I; and c) comparison of the fluctuations and magnitudes of Pu'u O'o measurements to other types of volcanoes.
