Empirical ground motion prediction

Annals of Geophysics, 1994
New methods of site-specific ground motion prediction in the time and frequency domains are presented. A large earthquake is simulated as a composite (linear combination) of observed small earthquakes (subevents) assuming Aki-Brune functional models of ...

Assessment of seismic liquefaction hazard in Shanghai based on ground motion intensity and Standard Penetration Test

Dizhi lixue xuebao, 2021
Shanghai is located in the alluvial plain of the Yangtze River Delta, the merge area of the Huangpu River and Suzhou River. The unique geographical and sedimentary environment have formed the shallow sand layers in Shanghai.

High Activity Earthquake Swarm Event Monitoring and Impact Analysis on Underground High Energy Physics Research Facilities

Energies, 2022
A seismic swarm is a series of earthquakes that occur in a small area over a short period of time. A sequence of earthquakes of this magnitude is unusual in Switzerland, and it is impossible to anticipate how it may unfold in the future.The seismic ...

Synthetic Ground-Motion Simulation Using a Spatial Stochastic Model with Slip Self-Similarity: Toward Near-Source Ground-Motion Validation

Terrestrial, Atmospheric and Oceanic Sciences, 2016
Near-fault ground motion is a key to understanding the seismic hazard along a fault and is challenged by the ground motion prediction equation approach. This paper presents a developed stochastic-slip-scaling source model, a spatial stochastic model with

The Effect of Magnitude M_w and Distance R_rup on the Fragility Assessment of a Multistory RC Frame Due to Earthquake-Induced Structural Pounding

Buildings, 2023
The effect of an intensity measure’s (IM’s) sufficiency property on the probabilistic assessment of reinforced concrete (RC) structures due to floor-to-floor structural pounding conditions is examined.
