| Zusammenfassung |
| Volcanoes exchange heat, gases and other fluids between the interrior of the Earth and its
atmosphere influencing processes both at the surface and above it. This work is devoted to
improve the knowledge on the parameters that control the anomalies in heat flux and
chemical species emissions associated with the diffuse degassing processes of volcanic and
hydrothermal zones.
We are studying and developing innovative medium range remote sensing technologies to
measure the variations through time of heat flux and chemical emissions in order to boost the
definition of the activity state of a volcano and allowing a better assessment of the related
hazard and risk mitigation.
The current methodologies used to measure heat flux (i.e. CO2 flux or temperature
gradient) are either poorly efficient or effective, and are unable to detect short to medium time
(days to months) variation trends in the heat flux. Remote sensing of these parameters will
allow for measurements faster than already accredited methods therefore it will
be both more effective and efficient in case of emergency and it will be used to
make quick routine monitoring. We are currently developing a method based on
drone-born IR cameras to measure the ground surface temperature that, in a purely
conductive regime, is directly correlated to the shallow temperature gradient. The
use of flying drones will allow to quickly obtain a mapping of areas with thermal
anomalies and a measure of their temperature at distance in the order of hundreds of
meters. Further development of remote sensing will be done through the use, on
flying drones, of multispectral and/or iperspectral sensors, UV scanners in order
to be able to detect the amount of chemical species released in the athmosphere. |
