Remote sensing of volcanos and volcanic terrains

Document Type


Publication Date



In recent years, much progress has been made in the use of both satellite and aircraft remote sensing techniques to collect data on the dynamics of volcanic eruptions and on the interactions between volcanos and the atmosphere and ecosphere. Measurements made in the ultraviolet provide estimates of the mass of SO2 released, while the hemispheric dispersal of eruption plumes can be tracked via weather satellites. Infrared images can be processed to produce temperature maps of lava flows and volcanic craters, and volumes of volcanic flows and cones can be measured via radar interferometry. Because the study of volcanos crosses many interdisciplinary boundaries, from geology and geophysics to atmospheric chemistry, climatology and ecology, the global perspective provided by satellite remote sensing techniques will become another valuable tool in the analysis of volcanos and their deposits. ©1989.
