The RST (Robust Satellite Techniques) approach is a multi-temporal scheme of data analysis recently implemented in an automatic processing chain developed at IMAA-DIFA laboratories in order to monitor Italian volcanoes in near real time. In this paper some recent results of satellite monitoring of Etna and Stromboli volcanoes are presented. Preliminary results of RST implementation on SEVIRI (Spinning...
Among the several satellite techniques developed for volcanic activity monitoring an original multi-temporal approach, named RST (Robust Satellite Techniques), has shown high performances in detecting hotspots, with a low false positive rate under different observational and atmospheric conditions. This approach has been successfully used to monitor volcanoes at different geographic location (e.g...
Volcanic clouds pose a serious threat for both aircrafts and passengers because of ash, which may cause serious damages to the flight control systems and to jet engines. Starting from 2007, an automatic satellite monitoring system has been implemented at IMAA (Institute of Methodologies of Environmental Analysis) to identify and track volcanic ash plumes using NOAA-AVHRR data. This system is capable...
We demonstrated how infrared satellite data can be used to drive numerical simulations of lava flow paths and produced a detailed chronology of lava flow emplacement while an eruptive event was ongoing. We evaluated the lava flow hazard on Etna volcano during the first 40 days of May 2008 eruption by means of the MAGFLOW cellular automata model. This model was developed for simulating lava flow paths...
Among the natural hazards, volcanoes represent one of major risk for both population and surrounding infrastructures, causing every year significant economical and environmental damages. Satellite remote sensing, thanks to multispectral data, high observational frequencies and global coverage, represents an important tool for volcanic activity monitoring, especially in remote areas where traditional...
