Seismic risk assessment
An evaluation of potential building performance and loss under specified earthquake assumptions. The scope may consider the structure, site conditions, and the earthquake scenario used in the analysis.
Why it matters
A loss estimate is not a prediction of a particular earthquake or a guarantee of life safety. Reports should identify methodology, scope, limitations, and the standard edition used. Legacy references to ASTM E2026-07 or E2557 editions should not be mistaken for confirmation of current requirements.
In practice
A project example
Two loss percentages are not directly comparable if they use different earthquake assumptions, confidence levels, or building information. Review the basis before making an insurance or investment decision.
