65 Seismic hazards and risk assessment in engineering practice

Active faults and seismic hazards in Alaska

“…DSHA focuses on defining the worst credible case without regard to the time probability of occurrence, exposure time, or design life of the facility under consideration. In PSHA, the hazards at a site are specified as the worst effects (for example, ground motions) that are statistically likely to occur in a specified time interval in terms of their probability of exceedance (Somerville and Moriwaki, 2003;Kramer, 1996;Abrahamson, 2006;Reiter, 1990). Application of risk assessment software (most commonly Hazus) has improved loss estimation and earthquake vulnerability assessment of infrastructure (Nishenko and others, 1998).…”

Physical Processes That Control Strong Ground Motion

“…These models play an essential role in seismic hazard analysis (e.g., Somerville and Moriwaki, 2003). These models play an essential role in seismic hazard analysis (e.g., Somerville and Moriwaki, 2003).…”

Paleoseismology

“…Paleoseismic data are used for seismic source characterization in hazard assessment (Field et al, 2009;Reiter, 1991Reiter, , 1995 and mitigation (Somerville and Moriwaki, 2002). Paleoseismic data are used for seismic source characterization in hazard assessment (Field et al, 2009;Reiter, 1991Reiter, , 1995 and mitigation (Somerville and Moriwaki, 2002).…”
