This paper presents results from a seismic vulnerability analysis of the components of hydropower systems in Canada. A number of dams and their associated components (hydropower plants, switchyards, transmission towers, and supplementary equipment) at selected locations in western and eastern Canada were analyzed in the study. The seismic vulnerability for a given hydropower component was estim...

In probabilistic seismic hazard analysis, one wants to calculate the probability of exceedance of a certain shaking level at a particular site. This requires a good understanding of the parameters that can influence seismic ground-motions. Bayesian networks are used to investigate the probabilistic dependencies between several parameters of the groundmotion domain. Problems specific to the doma...

Possibility of making queries on a spatial database, in order to obtain a decisional support is one of the most interesting features of GIS systems. This is possible through the expression of information which are implicit into database and useful for Geoprocessing operations in order to make a sort of data clustering. However, it is not sufficient to represent a priori non-modeling interaction...

today analyzing seismicity hazard urban different areas is critical and inevitable due to develop and to expand cities in seismically active zones and naturally, the hazard because the earthquake is more in the bigger cities and the necessity to consider these hazards would be increased. expanding the cities in iran seismically active zones caused to be necessary to analyze earthquake hazard. b...

Background: Earthquake-prone regions from the stable continental regions (like Peninsular India) warrant total seismic hazard estimation from possible sources — reservoir induced or tectonic. The Koyna region falls in the so-called stable continental region, though previously considered as aseismic because of its location in the Peninsular India, which was argued to be the continental Shield re...

Seismic hazard analysis is performed for a representative zone in Peru, including the city of Cusco, the citadel of Machupicchu and the archeological complex of Choquequirao, constituting the area with important Inca heritage. This is considered to be the first step towards developing a rational approach to seismic risk analysis of the Inca’s architectural heritage. An evaluation of the vulnera...

It is frequently conveyed, especially in the media, an idea of “increasing impact of natural hazards” typically attributed to their rising frequency and/or growing vulnerability of populations. However, for certain hazard types, this may be mostly a result of increasing population exposure due to phenomenal global population growth, especially in the most hazardous areas. We investigate tempora...

 Large-scale subsurface fluid injection has the potential to trigger earthquakes. In addition to seismic hazard, reactivation of faults and fractures during CO2 injection has the potential to compromise storage integrity. These risks need to be taken into account when selecting potential carbon capture and storage (CCS) sites.  Deployment of seismometers at current large-scale CCS projects (m...

Abstract The major earthquake events on August 2, 2019, and January 14, 2022, which devastated Banten City, gave an warning to the surrounding area, including Cilegon City. As area with several vital infrastructures, such as Merak Port, chemical factories, steel industries, power plants, City requires a seismic study that can provide information for planning retrofitting of building structures....
