We combine long-term records from aerial photographs, detailed mapping using survey-grade GPS, and ground-based lidar with meteorological monitoring. Sand dune migration rates are currently about 35 meters per year.
Describes the monitoring effort and provides real-time data of the current restless activity of the caldera, including earthquakes, ground deformation, and release of volcanic gas and plus link to volcano monitoring techniques.
Summarizes the eruptions of this spectacular volcano and the consequences for the surrounding landscape, explains how volcanoes like this form, and how we monitor their activity to mitigate hazards they pose.
