This multi-faceted project will 1) systematically acquire seismic reflection, bathymetric, sediment cores, water samples along the length of the lake system; 2) monitor earthquake activity along fault systems and from volcanoes; and 3) analyze time variations in land use and vegetation. Our synergistic approach to surveying this natural system is essential to evaluate the hazards imposed by natural and human activities in the region. The new data will inform the regional governments of the conservation implications of their development efforts in this biologically diverse, unique ecosystem.
