Journal ArticleDOI
Statistical Models for Earthquake Occurrences and Residual Analysis for Point Processes
TL;DR: Several classes of stochastic models for the origin times and magnitudes of earthquakes are discussed and the utility of seismic quiescence for the prediction of a major earthquake is investigated.
Journal ArticleDOI
The Centenary of the Omori Formula for a Decay Law of Aftershock Activity
TL;DR: In this article, the problem of fitting the modified Omori formula and related point process models to observational data is discussed mainly, and the problems of fitting these formulae to the observational data are discussed mainly.
Journal ArticleDOI
Space-Time Point-Process Models for Earthquake Occurrences
TL;DR: Several space-time statistical models are constructed based on both classical empirical studies of clustering and some more speculative hypotheses, and the goodness-of-fit of the models, as measured by AIC values, is discussed for two high quality data sets, in different tectonic regions as mentioned in this paper.
Journal ArticleDOI
On Lewis' simulation method for point processes
TL;DR: A simple and efficient method of simulation is discussed for point processes that are specified by their conditional intensities, based on the thinning algorithm which was introduced recently by Lewis and Shedler for the simulation of nonhomogeneous Poisson processes.
Journal ArticleDOI
Stochastic declustering of space-time earthquake occurrences
TL;DR: This article is concerned with objective estimation of the spatial intensity function of the background earthquake occurrences from an earthquake catalog that includes numerous clustered events in space and time, and also with an algorithm for producing declustered catalogs from the original catalog.
