We present a Python-based program designed for processing seismic catalogs and calculating seismicity parameters characterizing seismogenic area sources probabilistic hazard assessment. This tool provides detailed control over the database every step of workflow. The enables initial spatial-temporal analyses. It also includes key functionalities such as attributes manipulation, event filtering, homogenization to moment magnitude (Mw), well estimations completeness (Mc). Various declustering...
Incorporating faults as independent seismic sources in Probabilistic Seismic Hazard Assessment (PSHA) significantly influences the ground motion values when compared to classical zoning methods (CZM). This practice holds particular relevance for populations situated top or near active faults. Some hybrid (HM) and fault-based methods, implemented Spain, show that Peak Ground Acceleration (PGA) increase vicinity of fault traces. In some cases hazard levels may double, consistent with PGA...
We present a sensitivity analysis on the impact of input parameters and methods used results probabilistic seismic hazard assessment (PSHA). The accurate estimation in recurrence models (declustering fitting methods), along with selection scaling relationships for determining maximum magnitude ground motion (GMMs), enhance control over epistemic uncertainties when constructing logic tree, minimizing final calculation errors producing credible study region. This focuses Central America,...
In reinforced concrete buildings, non-structural elements (NSE), such as masonry infills and parapets, constitute the cause of a considerable number fatalities huge economic losses in developed countries, case medium magnitude earthquakes (4-6 Mw). As an example, during 5.2Mw 2011 Lorca (Spain) earthquake, falling debris from unreinforced NSE gave rise to nine incurred. The majority these were located 4 6-storey residential buildings. Within this framework, contribution addresses...
Abstract This research was undertaken at the Faculty of Engineering, University San Carlos de Guatemala (zone 12, City), with aim improving and updating study seismic geotechnical engineering in Guatemala. Known geophysical methods applied to geotechnics should be put into practice for purpose carrying out an appropriate site structural dynamic characterization, enhance knowledge hazards country. Using probabilistic hazard assessment, we determined a series control earthquakes that would...
This study compares methods that address two key aspects: how to quantify geological information and transfer it recurrence models, distribute the seismic potential between types of sources. These are as follows: 1) mom-rate method, 2) mom-slip 3) Hybrid Method Proposed (MHP), 4) method build hazard models including earthquake ruptures involving several faults named Seismic rate in fault systems (SHERIFS). The results show peak ground acceleration (PGA) values increase significantly vicinity...
