A class of probability models for earthquake occurrences, called shortterm exciting, long-term correcting (SELC) models, is presented. This class encompasses features of two different classes of models presently used in hazard analysis to characterize earthquake catalogs: (1) self-exciting models and (2) self-correcting models. It offers the potential for a unified approach to the analysis and ...

Geophysical and geochemical investigations concerning deformation events of tectonic interest at the underground laboratory of Gran Sasso have been carried out and possible correlations with local seismicity are also investigated. We have planned and realized an automatic multiparametric equipment (water temperature, electrical conductivity, pH, Rn) and from the May 1996 we performs automatic m...

One way to probe earthquake nucleation processes and the relation between stress buildup and seismicity is to analyze the sensitivity of seismicity to stress perturbations. Here, we report evidence for seasonal strain and stress (~2–4 kPa) variations in the Nepal Himalaya, induced by water storage variations which correlate with seasonal variations of seismicity. The seismicity rate is twice as...

The Region-Time-Length (RTL) algorithm has been applied to different instrumental catalogues to detect seismic quiescence before medium-to-large earthquakes in Italy in the last two decades. RTL performances are sensitive to the choice of spatial and temporal parameters. The method for automatic parameters selection developed by Chen and Wu has been applied to 12 Italian earthquakes with magnit...

An approach to compute optimum seismic design parameters is presented. It is based on the optimization of the expected present value of the total cost, which includes the initial cost of structures as well as the cost due to earthquakes. Different types of seismicity models are considered, including one for characteristic earthquakes. Uncertainties are included in some variables to observe the ...
