HAZUS Earthquake Loss Estimation Methods
Charles A. Kircher1; Robert V. Whitman2; and William T. Holmes3
Abstract: This paper provides background and historical perspective on the development of the earthquake loss estimation methods of
the HAZUS technology referred to as HAZUS Earthquake, describes the various modules of HAZUS Earthquake, and summarizes the
key concepts of these methods. HAZUS Earthquake modules calculate seismic hazard, evaluate the likelihood of various states of damage
to buildings, lifelines, and other components of the built environment, and estimate both direct and indirect losses resulting from this
damage. The focus of this paper is on building-related methods. The paper also describes two recent improvements to the HAZUS
Earthquake technology: 1 the Advanced Engineering Building Module AEBM and 2 use of ShakeMap ground motion data. The
AEBM allows expert users to develop “building-specific” damage and loss functions. ShakeMap ground motion data HAZUS may be
used to rapidly assess potential damage and loss immediately following an earthquake. The paper closes with a comparison of damage and
loss estimated using ShakeMap data with actual damage and loss due to the 1994 Northridge earthquake.
