“Basin effects” refers to trapped and reverberating earthquake waves in soft sedimentary deposits overlying convex depressions of the basement bedrock, which significantly alter frequency content, amplitude, duration seismic waves. This has played an important role on shaking intensity past earthquakes such as Mw 8.0 1985 Michoa'can, Mexico, 6.9 1995 Kobe, Japan, 7.8 2015 Gorkha, Nepal. Althoug...

Abstract We present a methodology for estimating fault geometry and utilizing the distance to shaking estimation improve accuracy of real-time estimates large earthquakes. Most earthquake early warning system currently seismic intensity with ground-motion prediction equations (GMPE) as function hypocenter distance. However, using computed from finite source model can This study proposes novel m...

A novel hybrid method coupling genetic programming and orthogonal least squares, called GP/OLS, was employed to derive new ground-motion prediction equations (GMPEs). The principal ground-motion parameters formulated were peak ground acceleration (PGA), peak ground velocity (PGV) and peak ground displacement (PGD). The proposed GMPEs relate PGA, PGV and PGD to different seismic parameters inclu...

2 Summary 20 We present a case study of the ranking and weighting of ground-motion prediction equations (GMPE) 21 for seismic hazard assessment of Enhanced Geothermal Systems (EGSs). The study region is Cooper 22 Basin (Australia), where a hot-fractured-rock project was established in 2002. We test the applicability 23 of 36 GMPEs based on stochastic simulations previously proposed for use at E...

The main objective of this study is estimating acceleration time history of 16 September 1978 Tabas earthquake incorporating the seismological/geological source-path and site model parameters by using finite-fault simulation approach. The method generalizes the stochastic ground-motion simulation technique, developed for point sources, to the case of finite faults. It subdivides the fault plane...

Modeling of Fourier amplitude spectra (FAS) seismic motions has gained much attention in engineering seismology. In the past few years, several ground motion prediction equations (GMPEs) and inter-frequency correlation structure FAS have been established. Due to many preferable characteristics FAS, probabilistic hazard/risk analysis is rapidly changing from ergodic, spectrum acceleration Sa ( T...

An attenuation relationship model belonging to a region with high earthquake hazard is important. It used for engineering studies know how the peak ground acceleration (PGA) value depends on distance where there are no stations. This study earthquakes magnitudes greater than 4 that IzmirNET recorded between 2009 and 2017 determine PGA through an artificial neural network (ANN) adaptive neuro-fu...

Sakarya province can be significantly affected by earthquakes on the North Anatolian Fault. Earthquake hazard includes some uncertainties. catalog data is needed for probabilistic earthquake calculations. In addition to current information, existing attenuation relationships, including characteristics region, should developed or their suitability checked. For this purpose, an analysis was carri...

The regional variability in earthquake ground-motion amplitudes for a given magnitude and distance in western North American environments was examined using ShakeMap data from small-to-moderate events. The abundance of data for small-tomoderate events in California allows average ground-motion levels, as a function of magnitude and distance, to be resolved with a high level of confidence. Groun...
