Streamlining the process by which data of active volcanism are obtained and processed is a desirable goal of volcano monitoring and hazard assessment programs. The JPL Volcano Sensor Web is an application of networked sensor technology that is being applied to volcano monitoring. The Sensor Web team has utilized the University of Hawaii automated system for processing data of volcanic thermal emission obtained by GOES (in geostationary orbits) and MODIS (on the Terra and Aqua spacecraft). This yields alerts on timescales of 15 minutes for GOES and less than 24 hours for MODIS data. Additionally, the Volcano Sensor Web utilizes the Hawaiian Volcano Observatory tiltmeter network (which covers Kilauea and Mauna Loa) which autonomously generates alerts when pre-set thresholds of inflation/deflation, likely to result in effusive activity, are exceeded. On notification, JPL automatically generates a spacecraft command sequence that is then transmitted to Goddard Space Flight Center for uplink to the Earth Observing 1 (EO-1) spacecraft. This enables rapid acquisition of high-spatial resolution hyperspectral (Hyperion) and multispectral (ALI) observations to be obtained of the target volcano as quickly as possible. Extending the use of autonomy, Autonomous Sciencecraft Experiment [1] software onboard EO-1 can then process the data and rapidly report the results (e.g., number and location of thermally active pixels).
