Data for Seismic properties of the Nazca oceanic crust in southern Peruvian subduction system
This supplementary file describes (1) data processing for teleseismic receiver function (RF), (2) RF amplitude inversion, and (3) calculation of velocities of candidate phases from experimental mineral physics data. 1. Data processing for teleseismic receiver function Identification of strong and sharp amplitudes of the P-to-S converted phase (hereafter, Ps) is crucial in this analysis. We try ...
متن کاملSeismic properties of the Nazca oceanic crust in southern Peruvian subduction system
a r t i c l e i n f o a b s t r a c t The horizontal Nazca slab, extending over a distance of ∼800 km along the trench is one of enigmatic features in Peruvian subduction zone. Increased buoyancy of the oceanic lithosphere alone due to the subduction of Nazca Ridge is insufficient to fully explain such a lengthy segment. We use data from the recent seismic experiment in southern Peru to find th...
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 کاملProbabilistic Seismic and Tsunami Hazard Analysis Conditioned on a Megathrust Rupture of the Cascadia Subduction Zone
This paper presents a methodology for probabilistic hazard assessment for the multihazard seismic and tsunami phenomena [probabilistic seismic and tsunami hazard analysis (PSTHA)]. For this work, a full-rupture event along the Cascadia subduction zone is considered and the methodology is applied to a study area of Seaside, Oregon, which is located on the US Pacific Northwest coast. In this work...
متن کاملPoisson model for earthquake frequency uncertainties in seismic hazard analysis
Frequency-magnitude distributions, and their associated uncertainties, are of key importance in statistical seismology. When fitting these distributions , the assumption of Gaussian residuals is invalid since event numbers are both discrete and of unequal variance. In general, the observed number in any given magnitude range is described by a binomial distribution which, given a large total num...
