| description | This work describes the structure and characteristics of the geographic
information system (GIS) developed for the urban seismic risk study of the
city of Almería (southern Spain), identifying the stages in which the
use of this tool proved to be very beneficial for adopting informed decisions
throughout the execution of the work.
<br><br>
After the completion of the regional emergency plans for seismic risk in
Spain and its subsequent approval by the National Civil Defence Commission,
the municipalities that need to develop specific local seismic risk plans
have been identified. Hence, the next action is to develop urban seismic
risk analyses at a proper scale (Urban Seismic Risk Evaluation – Risk-UR).
<br><br>
For this evaluation, different factors influencing seismic risk such as
seismic hazard, geotechnical soil characteristics, vulnerability of
structures of the region, reparation costs of damaged buildings and exposed
population are combined. All these variables are gathered and analysed
within a GIS and subsequently used for seismic risk estimation. The GIS
constitutes a highly useful working tool because it facilitates data
interoperability, making the great volume of information required and the
numerous processes that take part in the calculations easier to handle,
speeding up the analysis and the interpretation and presentation of the
results of the different working phases.
<br><br>
The result of this study is based on a great set of variables that provide a
comprehensive view of the urban seismic risk, such as the damage
distribution of buildings and dwellings of different typologies, the mean
damage and the number of uninhabitable buildings for the expected seismic
motion, the number of dead and injured at different times of the day, the
cost of reconstruction and repair of buildings, among others. These results
are intended for interpretation and decision making in emergency management
by unspecialised users (Civil Defence technicians and managers). |
