This paper provides a comparison between Earthquake Loss Estimation (ELE)
software packages and their application using an "Open Source Procedure for
Assessment of Loss using Global Earthquake Modelling software" (OPAL). The
OPAL procedure was created to provide a framework for optimisation of a
Global Earthquake Modelling process through:
1. overview of current and new components of earthquake loss assessment
(vulnerability, hazard, exposure, specific cost, and technology);
2. preliminary research, acquisition, and familiarisation for available ELE
software packages;
3. assessment of these software packages in order to identify the advantages
and disadvantages of the ELE methods used; and
4. loss analysis for a deterministic earthquake (Mw = 7.2) for the Zeytinburnu
district, Istanbul, Turkey, by applying 3 software packages (2 new and 1
existing): a modified displacement-based method based on DBELA (Displacement
Based Earthquake Loss Assessment, Crowley et al., 2006), a capacity spectrum
based method HAZUS (HAZards United States, FEMA, USA, 2003) and the Norwegian HAZUS-based
SELENA (SEismic Loss EstimatioN using a logic tree Approach, Lindholm et al., 2007) software which
was adapted for use in order to compare the different processes
needed for
the production of damage, economic, and social loss estimates. The modified
DBELA procedure was found to be more computationally expensive, yet had less
variability, indicating the need for multi-tier approaches to global
earthquake loss estimation. Similar systems planning and ELE software
produced through the OPAL procedure can be applied to worldwide
applications, given exposure data. |
