Central America Volcanoes: Cerro Negro, Ilopango, Irazu, Telica, and Turrialba

Abstract: Short write-ups and KML files of five volcanoes from the RU_CAGeoChem (Rutgers University Central America Geochemistry) database. The write-ups are general descriptions, aimed at the undergraduate level. They are background material for a MARGINS mini-lesson being created by Bob Stern and others. The KML files, when opened in Google Earth, show the sample locations. The volcanoes were selected to cover a range of compositions from basalt at Cerro Negro and Irazu, to rhyodacite at Ilopango. There is also a very large volcano, Irazu, a very small one, Cerro Negro, an intermediate size one, Telica, and a caldera, IIlopango. Turrialba has returned to activity after a long quiescence and so the Rutgers sample locations were placed in a kml file as well as a short description.
