HAZUS-MH MR3 FAQs: Earthquake Model Hazard/Scenario Definition

Is the duration of an earthquake considered in the damage models of buildings?

Duration effects are considered in the damage models through the kappa factor.  An earthquake with a moment magnitude equal to or less than 5.5 is considered to be an earthquake of short duration whereas an earthquake with a moment magnitude equal to or greater than 7.5 is considered to be an earthquake of long duration.  All other earthquakes are considered to be of moderate duration.

For additional information, the HAZUS Earthquake Technical Manual, as well as other HAZUS Manuals and guidance materials are available for download from the HAZUS Resources.
