Effects of Magnitude Uncertainties on Seismic Hazard Estimates
The standard probability tree methodology of probabilistic seismic hazard assessment (PSHA) allows for the explicit treatment of many kinds of uncertainty. These include both epistemic uncertainty (e.g., uncertainty in the parameters of the frequency-magnitude relation for a given source region, and in the form and parameters of relations for attenuation of strong shaking) and aleatory uncertai...
متن کاملUnderstanding Seismic Hazard and Risk Assessments: an Example in the New Madrid Seismic Zone of the Central United States
Seismic hazard and risk are fundamentally different concepts. Seismic hazard describes phenomena generated by earthquakes that have potential to cause harm, but seismic risk is the likelihood (chance) of experiencing a specified level of seismic hazard in a given time exposure. Seismic hazard occurs naturally and can be evaluated from instrumental, historical, and geological observations. Seism...
متن کاملCapturing the Uncertainty of Seismic Activity Rates in Probabilistic Seismic Hazard Assessments
A new two-step approach is proposed to quantify the uncertainties of the seismicity rate ν(M) estimated by Gutenberg-Richter relations of seismic area source zones in logic tree-driven probabilistic seismic hazard analysis. The first step makes use of the possibility that the uncertainties of the Gutenberg-Richter parameters α and β (or a and b), expressed by their covariance matrix C(α, β) (or...
متن کاملHazard assessments of manufactured nanomaterials.
BACKGROUND It has been difficult to make reliable hazard assessments of manufactured nanomaterials, because the nanomaterials form large agglomerations in both in vitro and in vivo studies. OBJECTIVE In the New Energy and Industrial Technology Development Organization (NEDO) Project of Japan, the physicochemical properties of many manufactured nanomaterials are being measured, and in vitro an...
متن کاملUpdating Seismic Hazard at Parkfield
The occurrence of the September 28, 2004 Mw=6.0 mainshock at Parkfield, California, has significantly increased the mean and aperiodicity of the series of time intervals between mainshocks in this segment of the San Andreas fault. We use five different statistical distributions as renewal models to fit this new series and to estimate the time-dependent probability of the next Parkfield mainshoc...
