...Bernice Bender Abstract Most seismic hazard analyses assume that earthquakes have a Poisson distribution and that data from recorded earthquakes can be used to predict future seismic activity in a region. Historic catalogs, however, may show different earthquake occurrence rates for regions...

Figure 1. The fit of both negative binomial and Poisson distributions to the number of earthquakes in each 5-yr period from 1960 to 2009. The mean of the fitted Poisson distribution is 33.2 per five years. The mean and standard deviation of the fitted negative binominal distribution are 33.2

In this article we outline a new 2D and 3D LB solution to the elastic wave equation in a Poisson solid using a regular lattice...

... consistent with properties (P1) and (P2). Inconsistencies occur in zone 5, with the Poisson distribution, and in zone 7, with the exponential distribution. Figure  3 shows that these inconsistencies are slight, although the distribution of the number of events in zone 5 reveals a non‐Poissonian peak...

The underestimation of the variability made under the Poisson hypothesis unavoidably leads to a high rejection frequency during the CSEP...

Knopoff abstract A statistically significant series of earthquakes in Southern California, 1934-1957, variously filtered to avoid aftershocks and events outside a localized area, has been tested for a Poisson distribution. It has been found that, for any of several methods of filtering, the data...
