Spring semester 2010
GE5185 Open-vent Volcanoes
Description and scope of the course: Open-vent volcanoes represent a broad class of systems that exhibit persistent, often varied activity and share the characteristic that there is generally an open path between the magma free surface and the atmosphere. Etna, Fuego, Kilauea, Pacaya, Popocatepetl, Santiaguito, and Stromboli are examples of volcanoes that spend long time periods in an open vent state. These systems often show periods of persistent, low-level activity interspersed with paroxysmal erutions, creating special challenges for hazard mitigation efforts. Because of the nature of the activity, which includes passive and explosive degassing, and varied seismic and airborne acoustic emissions, these volcanoes must be studied with an interdisciplinary approach that involves specialists from several fields. This course seeks to expose students to recent studies of open-vent system to facilitate integration of data in student research. Students will be required to read research papers, prepare presentations and discuss their work. Paricipation by students who are off campus will be enabled through web conferencing.
