Descr: We are studying the relation between elastic wave radiation and eruption intensity as measured with high-speed video, thermal imagery, and Doppler Radar. We are focus on two volcanoes located in Guatemala because of their reliable activity, varying magma chemistry (basaltic andesite and dacite), and superior viewing geometry (in both cases, imagers can be positioned to look across or down into the volcanic vent). Continuous acquisition of precisely timed seismic and infrasonic data is integral to the study because we are interested in learning about: 1) the coincidence of the seismo-acoustic source, 2) precursory seismicity prior to emission, and 3) the relation between intensity of eruptions and seismo-acoustic energy release.
