  • Continuous gas monitoring:

    Salvatore Lombardi, Department of Earth Sciences, University of Rome, Italy. Níels Óskarsson, Nordic Volcanological Institute, Reykjavík, Iceland.

Ragnar Stefánsson is also a coordinator of the project. The Department of Geophysics is in center position in the project. It operates and develops the SIL network and SIL center, which is the core of the geophysical observational facilities in Iceland. It serves the public and the authorities in Iceland with information and warnings related to earthquake and volcanic hazard, and is working on preparing an easy accessible seismic database and an early warning database for that purpose. The experience of the staff in creating the SIL system in Iceland and in information and warnings makes it to a very valuable partner in preparing the Icelandic infrastructures in the HOTSPOT project. Besides creating the SIL system the staff built up other systems in Iceland which will be valuable part of the HOTSPOT infrastructure, like the continuous volumetric borehole strainmeter system, continuous measurement of gravity, and now most recently continuous GPS measurements in the seismic areas of Iceland. The HOTSPOT dedicated Icelandic infrastructure will be operated as an integrated part of the SIL system at the Department of Geophysics. The testing of observational methods and attachment of new observational facilities to the system will be carried out in close cooperation with the staff members.
