“…For modeling the excitation the compatible with the regional hazard [34] site-based, stochastic ground motion model developed in [12] is adopted. The probability models for M and rrup along with adopted stochastic ground motion model result in peak ground acceleration (PGA) with probability of exceedance 10% in 50 years equal to 0.45 g, which is in agreement with literature results for Santiago [48].…”

“…The processing of all this data with the CRISIS2014 software (Ordaz et al, 2014) using the logic-tree approach allowed us to obtain a set of maps and graphics showing different representations of seismic hazard. All computations were conducted for 10% exceedance probability in 50 years (corresponding to a 475-year return period).…”

“…Only results for mainland Cuba were computed. The calculations of seismic hazard were performed with program CRISIS2014 (Ordaz et al, 2014), which is capable of processing together both the classical cases of areas, lines, and points sources with associated Gutenberg-Richter recurrence relations, and zoneless cases with generalized Poissonian occurrence model.…”

A new seismic hazard study for Cuba is presented in terms of maps and uniform hazard spectra (UHS). An earthquake catalog from 1502 to 2012 was prepared for the region 16°-24°N and 67°-86°W, and was homogenized to M w and cleaned for aftershocks and foreshocks. A 16-arm logic-tree computation corresponding to four source branches and four ground-motion prediction equations (GMPEs) was conducted (using only published GMPE relations due to a lack of local strongmotion data). For each source model, the seismicity parameters (β, λ, and M max) were developed. The results were obtained and are presented in terms of maps and UHS graphs for a 475-year return period, but results for other return periods are easily obtained. The influence of different branch weighting in the logic tree was investigated with respect to the final results. Peak ground acceleration values for Cuba were found to vary from less than 75 to 230 cm=s 2 .

“…a global earthquake catalog, a global database of active faults). This approach was used, for example, by Weatherill and Pagani (2014) to explore the feasibility of a uniform approach to global hazard modeling and by Ordaz et al (2014) to support the risk calculation within the 2013 version of the Global Assessment Report on Disaster Risk Reduction (GAR).…”

The 2018 version of the Global Earthquake Model: Hazard component

In December 2018, at the conclusion of its second implementation phase, the Global Earthquake Model (GEM) Foundation released its first version of a map outlining the spatial distribution of seismic hazard at a global scale. The map is the result of an extensive, joint effort combining the results obtained from a collection of probabilistic seismic hazard models, called the GEM Mosaic. Together, the map and the underlying database of models provide an up-to-date view of the earthquake threat globally. In addition, using the Mosaic, a synopsis of the current state-of-practice in modeling probabilistic seismic hazard at national and regional scales is possible. The process adopted for the compilation of the Mosaic adhered to the maximum extent possible to GEM’s principles of collaboration, inclusiveness, transparency, and reproducibility. For each region, priority was given to seismic hazard models either developed by well-recognized national agencies or by large collaborative projects involving local scientists. The version of the GEM Mosaic presented herein contains 30 probabilistic seismic hazard models, 14 of which represent national or sub-national models; the remainder are regional-scale models. We discuss the general qualities of these models, the underlying framework of the database, and the outlook for the Mosaic’s utility and its future versions.
