FRAGILE EARTH: Geological Processes from Global to Local Scales and Associated Hazards (4-7 September 2011) Paper No. 34-2 Presentation Time: 09:05-09:35 VOLCANO DEFORMATION MONITORING: INNOVATIONS AND SCALES, NOISE AND DATAWALTER, Thomas R., Physics of the Earth, GFZ Potsdam, Potsdam 14478 Germany, twalter@gfz-potsdam.deLocal volcano eruptions may lead to cross border natural disasters, as last documented during the 2010 Eyjafjallajkull eruption. Although such events often arise from a cascade of processes, volcano deformation data acquired before the eruption provided an important information source about the state of activity before eruption onset. In many cases, deformation measurements even successfully contributed to eruption forecast. Here I firstly discuss the lessons learned from such well monitored volcano activities, and outline the state of the art technical advancements of data gathering. Deformation observations may be on high spatial scale, or on high temporal scale, though only few methods combine high spatial and temporal scales. Many of the methods are expensive and complex, thus not pragmatic for most volcano observatories. Methods such as GPS, differential satellite radar interferometry (InSAR) and their time series (SBAS and PSI), levelling and innovative optical and microwave sensing from space and the ground are reviewed, and their potential for improved volcano monotoring and hazard assessment discussed.FRAGILE EARTH: Geological Processes from Global to Local Scales and Associated Hazards (4-7 September 2011) General Information for this Meeting Session No. 34Plenary: Local-Scale Processes: Local Events with Global Impact (Volcanic Eruptions)Ludwig-Maximilians-Universitt Mnchen: E 120 (Grosse Aula)08:30-10:40, Wednesday, 7 September 20111

Intensity functionThe digital image correlation concept in a nutshellPixel offsets (deformation) and particle trajectories are determinable3WP7. Determination and evolution of eruption source parametersOur task: Cameras will be installed for study of ground deformation and plume dynamics of 3 selected volcanoes. Static IPs allow configuration changes in times of increased activity.Milestone: Tool development for determining particle trajectories

WP8. Distribution of eruptive products and ash dispersion Our task: Quantify the height and paths of eruptive products and the time dependent changes in an eruptive cloud through near real-time camera monitoringMilestone: Algorithm development and improvement for cameras.
