Original Title:
Assessment of natural hazards (volcanic, seismic, landslide, flood and wildland fire) in Nisyros island and the use of modern cartography methods (Web GIS)
Translated title:
Εκτίμηση φυσικών κινδύνων (ηφαιστειακός, σεισμικός, κατολισθητικός, πλημμυρικός και δασικές πυρκαγιές) της νήσου Νίσυρος και η χρήση σύγχρονων χαρτογραφικών μεθόδων (Web GIS)
Summary:
Nisyros is a stratovolcano structured by Quaternary volcanic formations. Placed
at the eastern edge of the Hellenic active volcanic arc, it has a special form
of volcanic and geothermal characteristics interesting displays as ideal
conditions for the existence and operation of a high-enthalpy geothermal field.
With the use of modern mapping and processing software, satellite images
interpretation, analysis of geological and morphotectonic characteristics of
the Nisyros volcano based on other researchers' results, was attempted a study
of potential risks the island might face.
Because of the particular geological, tectonic and morphological
characteristics, the following hazards could occur:
• Volcanic hazard.
• Seismic hazard due to tectonic movements in the wide region of Nisyros.
• Landslides that may be associated with earthquakes, magmatism and volcanic
activity.
• Forest fires.
• Floods.
• Extreme weather events such as heat waves and storms.
An attempt in this thesis is to highlight and promote Web-GIS technology. The
evolution of Web-based GIS technology and the client-server architecture have
been an important role in data sharing. The development and expansion of the
Internet provides two key capabilities which can significantly help
geoscientists. First, the Web-GIS allows the visual interaction with data, and
second, due to the almost ubiquitous nature of the Internet, the geospatial
data can be widely accessible.
