Indonesian Earthquake Fatality Model.
This model was developed by Institut Teknologi Bandung (ITB) and implemented by Dr. Hadi Ghasemi, Geoscience Australia.
Reference:
Indonesian Earthquake Building-Damage and Fatality Models and Post Disaster Survey Guidelines Development, Bali, 27-28 February 2012, 54pp.
Algorithm:
In this study, the same functional form as Allen (2009) is adopted to express fatality rate as a function of intensity (see Eq. 10 in the report). The Matlab built-in function (fminsearch) for Nelder-Mead algorithm was used to estimate the model parameters. The objective function (L2G norm) that is minimised during the optimisation is the same as the one used by Jaiswal et al. (2010).
The coefficients used in the indonesian model are x=0.62275231, y=8.03314466, zeta=2.15

Caveats and limitations:
The current model is the result of the above mentioned workshop and reflects the best available information. However, the current model has a number of issues listed below and is expected to evolve further over time.
Note: Because of these caveats, decisions should not be made solely on the information presented here and should always be verified by ground truthing and other reliable information sources.
