... here the latest version of the HOTSAT system for thermal monitoring of volcanoes ( Ganci et al. 2011 b ); its algorithms, products, web interface and implementation are described, together with a ground-based validation of the volcanic heat flux estimation. HOTSAT is currently operational on the Mt...

... the HOTSAT volcano hotspot detection system, which works with satellite thermal infrared data, and the MAGFLOW lava flow emplacement model, which is able to relate the flow evolution to eruption conditions at the vent. We used HOTSAT to analyze Moderate Resolution Imaging Spectroradiometer (MODIS...

... threshold algorithm, MODVOLC one temporal algorithm, RST Volc and three hybrid algorithms, MIROVA MyMET and MyMOD HOTSAT. To these we can add two physical algorithms, AVHotRR and the Kalman filter; these are algorithms that use the physical character of the hot spot to confirm...

... products (open/restricted), (iv) the dissemination environment (static web or interactive Web-GIS) and/or (v) whether systems focus on a single volcanic target or region (e.g. HOTSAT system) and those allowing global monitoring of volcanoes (e.g. MODVOLC). HOTSAT, for example, is a monitoring system...

... ( Wright et al. 2004 ). MODVOLC was intended to provide a rapid response to a variety of volcanic activities at the cost of detection accuracy. To overcome limits due to a fixed threshold, different advanced algorithms have been proposed. HOTSAT Satellite Monitoring System integrates MODIS and SEVIRI...

... eruption. The TADRs varied between 20–40 and <1 m 3 s −1 . Four systems were able to provide data during this event: MODVOLC, RST-Volc, MIROVA and HOTSAT (see Appendix A ( Harris et al. , this volume, in press ) for the directory of operational hotspot systems). Results from each of these systems...
