| Zusammenfassung |
Rapid loss estimation after potentially damaging earthquakes is critical for
effective emergency response and public information. A methodology and
software package, ELER-Earthquake Loss Estimation Routine, for rapid estimation of earthquake shaking and losses
throughout the Euro-Mediterranean region was developed under the Joint
Research Activity-3 (JRA3) of the EC FP6 Project entitled "Network of
Research Infrastructures for European Seismology-NERIES". Recently, a new
version (v2.0) of ELER software has been released. The multi-level
methodology developed is capable of incorporating regional variability and
uncertainty originating from ground motion predictions, fault finiteness, site
modifications, inventory of physical and social elements subjected to
earthquake hazard and the associated vulnerability relationships. Although
primarily intended for quasi real-time estimation of earthquake shaking and
losses, the routine is also equally capable of incorporating scenario-based
earthquake loss assessments.
This paper introduces the urban earthquake loss assessment module (Level 2)
of the ELER software which makes use of the most detailed inventory
databases of physical and social elements at risk in combination with the
analytical vulnerability relationships and building damage-related casualty
vulnerability models for the estimation of building damage and casualty
distributions, respectively. Spectral capacity-based loss assessment
methodology and its vital components are presented. The analysis methods of the
Level 2 module, i.e. Capacity Spectrum Method (ATC-40, 1996), Modified
Acceleration-Displacement Response Spectrum Method (FEMA 440, 2005),
Reduction Factor Method (Fajfar, 2000) and Coefficient Method (ASCE 41-06,
2006), are applied to the selected building types for validation and
verification purposes. The damage estimates are compared to the results
obtained from the other studies available in the literature, i.e. SELENA
v4.0 (Molina et al., 2008) and ATC-55 (Yang, 2005). An urban loss assessment
exercise for a scenario earthquake for the city of Istanbul is conducted and
physical and social losses are presented. Damage to the urban environment is
compared to the results obtained from similar software, i.e. KOERILoss
(KOERI, 2002) and DBELA (Crowley et al., 2004). The European rapid loss
estimation tool is expected to help enable effective emergency response, on
both local and global level, as well as public information. |
