A new strong ground motion model for predicting Peak Ground Acceleration (PGA), pseudo-acceleration spectra and displacement spectra in Iran [PDF]
مهندسی عمران شریفDue to the inelasticity of the ground and geometric expansion, seismic waves are reduced by moving away from the center of wave propagation, which is called the attenuation of seismic waves.

Probabilistic assessment of the seismic Peak Ground Acceleration (PGA) at seven Colombian cities
Revista Sul-americana de Engenharia Estrutural, 2022 This paper presents a probabilistic assessment of peak ground acceleration (PGA) observations at seven Colombian cities located in regions with intermediate and high seismic activity. Frequency histograms of the annual exceedance rates were determined using historical data of the annual rate of exceedance for pre-established values of PGA.

Ground Motion Prediction of High-Energy Mining Seismic Events: A Bootstrap Approach
Energies, 2023 Induced seismicity has been a serious problem for many coal mines in the Upper Silesian Coal Basin in Poland for many decades. The occurring mining tremors of the rock mass generate seismic vibrations that cause concern to the local population and in ...

Analisis PGA (Peak Ground Acceleration) Pulau Lombok Menggunakan Metode Pendekatan Empiris [PDF]
Jurnal Fisika dan Aplikasinya, 2020 Pulau Lombok berada di antara dua lempeng besar yaitu lempeng Asia dan lempeng Australia sehingga Pulau Lombok sangat rawan akan terjadi guncangan gempa bumi dan pergeseran tanah. Faktor yang mempengaruhi niai percepatan tanah maksimum yaitu kondisi geologi dan karakteristik wilayah tersebut. Penelitian ini bertujuan untuk menganalisis nilai percepatan

Dizhen xuebao, 2022 选取了50条实际地震动，采用一维场地等效线性化方法分别对均匀半空间场地和成层半空间场地进行地震响应分析，同时选择效益性作为判别标准来探究最优地震动峰值指标（峰值加速度PGA，峰值速度PGV，峰值位移PGD）随埋深变化的规律。研究结果表明：对于选取的两类场地，最优地震动峰值指标均随埋深的改变而变化，埋深浅时PGA效益性最优，随着埋深的增加，效益性最优逐渐由PGA转变至PGV；PGA与PGV转折的交点位置随场地剪切波速的不同而不同，且该转折交点位置与场地剪切波速呈线性相关。

Estimation of Peak Ground Acceleration (PGA) for Peninsular Malaysia using geospatial approach [PDF]
IOP Conference Series: Earth and Environmental Science, 2016 Among the various types of natural disasters, earthquake is considered as one of the most destructive events which impose a great amount of human fatalities and economic losses. Visualization of earthquake events and estimation of peak ground motions provides a strong tool for scientists and authorities to predict and mitigate the aftereffects of ...
