“…Notably, the linear elastic and the equivalent linear model overestimated ground motion. In general, the results were consistent with Mase, et al [2], who reported that the equivalent linear model can overestimate PGA. In addition, the performance of the linear elastic model showed a high overestimation compared to the equivalent linear model.…”

“…The seismic ground response problem has been investigated by Hashash, et al [1]. The basic framework for seismic ground response analysis is the propagation of seismic waves through horizontal soil layers [2]. There are two major methods to analyze the seismic ground response, i.e.…”

“…For instance, the SHAKE program by Schnabel, et al [3] adopted the equivalent linear method while the NERA program by Bardet and Tobita [6], Cyclic 1D by Elgamal, et al [7], FLIP by Iai, et al [8], and DEEPSOILS by Hashash, et al [5] used non-linear methods. These computer programs are helpful in seismic wave propagation analysis for engineering practice as well as for theoretical problems [2]. An engineer must fully understand how these programs work, especially regarding their reliability and the models they use.…”

Several soil models, such as linear elastic, equivalent linear, and nonlinear models, are employed in seismic ground response analysis. The aim of this study was to validate the seismic responses at ground surface of several soil models with the vertical array record of the Kobe earthquake. One-dimensional seismic response analyses were performed at Port Island using several soil models. The responses at ground surface from the simulated soil models were validated with the vertical array record of the Kobe earthquake. The results showed that the extended hyperbolic model yielded the most appropriate response according to the Kobe earthquake's recorded motion. This means that this model can be considered a suitable soil model to predict the response of strong earthquakes. In general, the results support the recommendation to select the most appropriate soil model for seismic ground response analysis.

“…The ambient noise and its applicability have been widely observed by several researchers, such as Lachet et al [9], El Hady et al [10], and Mase et al [11]. In the implementation, microtremor is applicable to observe the geophysical characteristic.…”

“…The main interpretation results of microtremor measurement is the horizontal to vertical spectral ratio (H/V ratio) corresponding to frequency (f). Mase et al [11] mentioned that H/V ratio also reflects the transfer function of ground site, which is addressed to estimate the predominant period (To), the H/V ratio, and the shear wave velocity (Vs) profile.…”

During the 8.6 Mw Bengkulu-Mentawai Earthquake Ratu Agung District was identified as an impacted area. This paper aims to deliver the seismic vulnerability based on geophysical observation. This study was initiated by performing the ambient noise measurement to obtain the geophysical characteristic, such as amplification and predominant frequency. Furthermore, the vulnerability index analysis was performed from the geophysical information collected from the investigation. To observe the tendency of ground damage during the earthquake, ground damages analysis is also performed. All results are depicted into the microzonation maps. The results showed that the amplification and predominant frequency on site are generally ranging from 3 to 5 and 5 to 8 Hz, respectively. The seismic vulnerability index in study area is up to 10-3. The results showed that during the Bengkulu-Mentawai Earthquake, the investigated sites could be possible to undergo crack settlement which can trigger massive sand boiling in the study area.
