Seismic hazard analysis of Peru

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1992
Abstract This paper provides a hazard map of Peru, showing peak ground acceleration (PGA) levels on bedrock, with a 10% probability of exceedance for a 50 yr time period. The probabilistic PGA map for Peru and adjacent areas may be used as a reference by designers and engineers to obtain the primary input for initially quantifying seismic loads ...

Seismic hazard analysis—Computer validation

Computers & Structures, 1996
The purpose of this paper is to discuss the validation procedures used for validating a computer model developed for seismic hazard analysis. An elaborate and detailed computer model ([1] J. M. Ferritto, seismic hazard analysis, users guide #UG-0027, NCEL, Port Hueneme (1993)) was developed at the Naval Civil Engineering Laboratory (NCEL), Port Hueneme,

Seismic Hazard Analysis of Lifelines

Journal of the Structural Division, 1982
Methods for assessing the seismic safety of a lifeline system are developed; with part of the study being devoted to the development of a relation between the earthquake intensity and the distance for near-source regions. The attenuation of maximum ground motion intensity with distance is examined.

Probabilistic seismic hazard analysis for seismic sequences

2013
Earthquakes are typically clustered both in space and time. Seismic h azard , expressed in terms of rate of exceedance of a ground motion intensity measure , classically refers to ma i nshock s, which means that such a rate is computed filtering the rate o f occurrence of events of largest magnitude within each cluster of earthquakes.

Probabilistic Seismic Hazard Analysis for Induced Seismicity

2020
In recent times, there has been increased seismicity in geologically stable basins in North America, thought to be associated with hydraulic fracturing and/or waste water disposal activities. Induced events could generate a seismic hazard higher than natural seismicity, particularly in areas with small-to-moderate natural background seismicity, leading

Seismic hazard analysis: How to measure uncertainty?

Computers & Structures, 1998
Summary: Applications of probabilistic seismic hazard analysis demand the adoption of a model (i.e. of the forms of a certain number of correlations and probabilistic distributions) and the estimate of the parameters of the model. As a measure of uncertainty in the calculation of the expected value of a given quantity (for instance the peak ground ...

Seismic Hazard Analysis with Randomly Located Sources

Natural Hazards, 1994
Demarcation of areal and linear seismic sources involves a certain degree of uncertainty and this should be reflected in the final seismic hazard results. The uncertainty associated with the description of the geographical coordinates of a source zone boundary is modeled by introducing the concept of ‘random boundary’, where the location of the ...

Influence of spatial variability of soil strength parameters on probabilistic seismic slope displacement hazard analysis

Engineering Geology, 2020
Permanent sliding displacement analysis is commonly used to evaluate the seismic performance of slopes. Specifically, the fully probabilistic seismic slope displacement hazard analysis (PSSDHA) has attracted increasing attention recently, since it ...

Probabilistic seismic hazard analysis in Nepal

Earthquake Engineering and Engineering Vibration, 2013
The seismic ground motion hazard for Nepal has been estimated using a probabilistic approach. A catalogue of earthquakes has been compiled for Nepal and the surrounding region (latitude 26° N and 31.7° N and longitude 79° E and 90° E) from 1255 to 2011.
