Seismic hazard analysis for critical infrastructures in California

A new seismic hazard analysis using FOSM algorithms

“…Besides, it must be noted that a complex method (e.g., PSHA) is not necessarily more reliable than a simple one (e.g., DSHA), considering the natural randomness in earthquake not fully understood [26,27]. Therefore, like many others, this FOSM seismic hazard assessment, which is repeatable with the same input data, is a new, scientific reference to the levels of seismic hazard in the two major cities in Taiwan.…”

“…It has been pointed out that not a seismic hazard assessment is perfect without challenge [26], so that the robustness of a seismic hazard analysis is not related to methodology, but to a transparent and repeatable process [27]. Besides, it must be noted that a complex method (e.g., PSHA) is not necessarily more reliable than a simple one (e.g., DSHA), considering the natural randomness in earthquake not fully understood [26,27].…”

A first-order second-moment calculation for seismic hazard assessment with the consideration of uncertain magnitude conversion

“…Mualchin (2005) commented that no seismic hazard analysis should be perfect without challenge, given our limited understanding of the random earthquake process. Moreover, Kluegel (2008) considered that the key to a robust seismic hazard study is a transparent and repeatable process, regardless of methodology.…”

A Proposed Mid-Holocene Age Definition for Hazardous Faults in California

“…Therefore, uncertainties abound, but practicing geologists must be realistic and must arrive at reasonable conclusions. Inherently, as in many geoscience investigations, professional judgment will be required (Terzaghi, 1950;Mualchin, 2005) by both the applicants' licensed geologists and by agency reviewers.…”
