"Despite the rapid advances in technology in many fields, accurate estimation of earthquake damage remains an art till to date. Modern catastrophe modeling of earthquakes is conventionally designed as a probabilistic model and often entails several fundamental shortcomings which depart from the engineering science of building damage. A damage estimation model program is introduced to compute an indication of the expected relative extent of damage to buildings. This methodology has been validated with case histories of four recent large earthquakes, namely the 2011 Tohoku Earthquake, 2007 Bengkulu Earthquake, 2011 Christchurch Earthquake and 1999 Chi-Chi Earthquake."
