Abstract This study introduces an improved hypocentral version of the space‐time Epidemic‐Type Aftershock Sequence (ETAS) model, entitled as 3D‐finite source (3D‐FS) ETAS and applies it to analysis Southern California earthquake catalog. By stochastic reconstruction, we are able reconstruct patterns aftershock productivity density along mainshock ruptures. Detailed reveals that: (1) Directly tr...

ABSTRACT The epidemic-type aftershock sequence (ETAS) model is a powerful statistical to explain and forecast the spatiotemporal evolution of seismicity. However, its parameter estimation can be strongly biased by catalog deficiencies, particularly short-term incompleteness related missing events in phases high-seismic activity. Recent studies have shown that these fluctuations completeness mag...

In this article we present a space–time epidemic-type aftershock sequence (ETAS) model for the area of Hungary, motivated by goal its application in insurance risk models. High-quality recent instrumental data from period 1996–2021 are used parameterization, including nearby Zagreb and Petrinja event sequences. earthquake-triggering equations our ETAS model, replace commonly modified Omori law ...

[1] On the basis of the epidemic-type aftershock sequence (ETAS) model and the thinning procedure, this paper gives the method about how to classify the earthquakes in a given catalogue into different clusters stochastically. The key points of this method are the probabilities of one event being triggered by another previous event and being a background event. Making use of these probabilities,...

The complete mitochondrial DNA (mtDNA) control region from Capromys pilorides, an autochthon Cuban rodent, was sequenced and compared to two other species of hystricognath caviomorph rodents, in order to know patterns of variation and to explore the existence of previously described domains and other elements in rodents. The results revealed that the complete D-loop region of this species is 13...

In this paper, the first version of the software SEDA (SEDAv1.0), designed to help seismologists statistically analyze earthquake data, is presented. The package consists of a user-friendly Matlab-based interface, which allows the user to easily interact with the application, and a computational core of Fortran codes, to guarantee the maximum speed. The primary factor driving the development of...
