Earthquake Likelihood Model Testing
The Regional Earthquake Likelihood Models (RELM) project aims to produce and evaluate alternate models of earthquake potential (probability per unit volume, magnitude, and time) for California. Based on differing assumptions, these models are produced both to test the validity of their assumptions and explore which models should be incorporated in seismic hazard and risk evaluation. Tests based...
متن کاملAssessing the Quality of Earthquake Catalogues: Estimating the Magnitude of Completeness and Its Uncertainty
We introduce a new method to determine the magnitude of completeness Mc and its uncertainty. Our method models the entire magnitude range (EMR method) consisting of the self-similar complete part of the frequency-magnitude distribution and the incomplete portion, thus providing a comprehensive seismicity model. We compare the EMR method with three existing techniques, finding that EMR shows a s...
متن کاملEarthquake Analysis of Spatial Rod Systems
A master element to be employed as a general spatial rod finite element is presented. This spatially curved and pretwisted element can have variable cross-section and variable curvature change. It may also be resting on an elastic foundation. Also, a finite element formulation for a general earthquake analysis of spatial rods is presented. The theoretical foundation has lead to a general-purpos...
متن کاملMultiscale Geometric Analysis for 3-D Catalogues
We have developed tools for analysis of 3-D volumetric data which allow sensitive characterizations of point clouds containing filamentary structures. Our approach involves multiscale X-ray transforms of the data volume. The idea is that cubes of all different locations and scales are extracted from the data volume and then analyzed by integrating along lines (X-Rays) of all different orientati...
متن کاملResults of the Regional Earthquake Likelihood Models (RELM) test of earthquake forecasts in California.
The Regional Earthquake Likelihood Models (RELM) test of earthquake forecasts in California was the first competitive evaluation of forecasts of future earthquake occurrence. Participants submitted expected probabilities of occurrence of M ≥ 4.95 earthquakes in 0.1° × 0.1° cells for the period 1 January 1, 2006, to December 31, 2010. Probabilities were submitted for 7,682 cells in California an...
