Davies 2006 <p>Rapid response to the onset of volcanic activity allows for the early assessment of hazard and risk [<i>Tilling</i>, 1989]. Data from remote volcanoes and volcanoes in countries with poor communication infrastructure can only be obtained via remote sensing [<i>Harris et al.</i>, 2000]. By linking notifications of activity from ground-based and spacebased systems, these volcanoes can be monitored when they erupt.</p><p>Over the last 18 months, NASA's Jet Propulsion Laboratory (JPL) has implemented a Volcano Sensor Web (VSW) in which data from ground-based and space-based sensors that detect current volcanic activity are used to automatically trigger the NASA Earth Observing 1 (EO-1) spacecraft to make highspatial-resolution observations of these volcanoes.</p> application/pdf 10.1029/2006EO010002 en American Geophysical Union Sensor web enables rapid response to volcanic activity article
