Monitoring of Volcanic Activity (Kos – Yiali - Nisyros)
islands of Nisyros, Yiali, Kos, Santorini, Milos, Poros, Aegina and the
Peninsula of Methana constitute the Hellenic Volcanic Arc. The eastern
sector of the arc, including the islands of Kos, Yiali and Nisyros
seems to be geodynamically very active since it comprises the largest
volumes of volcanic products and is at present a region of high
volcanoes represent several natural hazards for populated regions.
These hazards often occur as combinations of earthquakes,
gas-explosions and hydrothermal eruptions, volcanic eruptions,
landslides, mudflows, tsunamis etc. For that the research project
GEOWARN (IST 1999-12310) financed by the European Union has been
objectives of this scientific study are to conduct an integrated
informative, volcanological, geophysical and geochemical project to
assess volcanic and seismic hazards related in the most active part of
the Eastern Mediterranean by the help of a GIS database, as well as an
integrated geo-spatial multimedia system for the region.
use of a Digital Elevation Model (DEM) is important for any
geo-environmental study. A selection of DEMs in different scales with
various resolutions for Kos - Yiali - Nisyros - Tilos islands was
produced. The DEMs will serve as the base for thematic applications, as
well as the base for production of a great variety of maps.
