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...

Analysis of the seismic risk to a structure requires assessment of both the rate of occurrence of future earthquake ground motions hazard and the effect of these ground motions on the structure response . These two pieces are often linked using an intensity measure such as spectral acceleration. However, earth scientists typically use the geometric mean of the spectral accelerations of the two ...

Bengkulu City is an area in Indonesia that has a high seismic intensity. This very vulnerable to undergo earthquakes. Therefore, there necessity study the hazard assessment this area. paper presents vulnerability based on ground response analysis combined with probabilistic assessment. The soil profiles around are investigated using geophysical survey by microtremor and analysis. motion of soft...

Probabilistic Seismic Hazard Assessment (PSHA) evaluates the probability of exceedance a given earthquake intensity threshold like Peak Ground Acceleration, at target site for exposure time. The stochasticity occurrence seismic events is modelled by stochastic processes and propagation wave in soil typically evaluated empirical relationships called Motion Prediction Equations. large uncertainty...
