| Zusammenfassung |
| Geological hazards in the Azores archipelago include earthquakes,
volcanic eruptions, degassing phenomena and landslides, being the cause of
thousands of deaths and severe damage and loss. To reduce the impact of
future events it is necessary to improve the emergency response and
reinforce land-use planning, and this has given rise to the development of
AZORIS, a GIS database for risk analysis in the Azores. At present this
computer-based system comprises nine main dynamic data sets where elemental,
monitoring and historical data are grouped in layers of first and second
order. The logical structure of the database was conceived in order to
facilitate interactivity between data sets and to guarantee the evolution of
the system, as determined by the input and the generation of new and more
detailed information. Archive organization was designed taking into account
regional and local aspects of geological hazard. In order to ensure
consistency of the database and the quality of the data within it, an
internal process of validation was included. |
