Stratigraphic Determination Based on Shear Wave Velocity for Earthquake Disaster Mitigation in Lebong District

JPFT (Jurnal Pendidikan Fisika dan Teknologi)
Bengkulu Province, including North Bengkulu and Lebong, is located in the subduction zone of the Indo-Australian and Eurasian plates, which makes the region prone to earthquakes. This research focuses on earthquake disaster mitigation in the Lemeu area,

Squeezing Kappa (κ) out of the transportable array: A strategy for using bandlimited data in regions of sparse seismicity [PDF]

, 2017
The κ parameter (Anderson and Hough, 1984), and namely its site-specific component (κ0), is important for predicting and simulating high-frequency ground motion.

A quantitative assessment of GeoNet earthquake location quality in Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 941-954, December 2025.
ABSTRACT Tens of thousands of earthquakes are located by GeoNet across Aotearoa every year. However, spatial variability – both in station coverage and earthquake distributions – produce heterogeneity in earthquake location quality throughout the GeoNet catalogue.

Site Effects in Structural Response Predictions of Inelastic SDOF Oscillators [PDF]

, 2012
We study how the inelastic structural response predicted via synthetic seismograms is affected by the selection of site response models in ground motion simulations.

Multi‐fidelity data meta‐learning approach for seismic response prediction of high‐rise shear wall buildings

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 29, Page 5512-5533, 9 December 2025.
Abstract Rapid and accurate estimation of seismic responses in city‐scale buildings is critical for post‐earthquake loss assessment and pre‐event identification of vulnerable buildings. However, conventional numerical simulation methods struggle to balance efficiency and accuracy when applied to large‐scale buildings, while existing data‐driven methods

A Comparative Study on the VS30 and N30 Based Seismic Site Classification in Kahramanmaras, Turkey

Advances in Civil Engineering, 2020
Assessment of seismic site classification (SSC) using either the average shear wave velocity (VS30) or the average SPT-N values (N30) for upper 30 m in soils is the simplest method to carry out various studies including site response and soil-structure ...

PENGUKURAN VS30 MENGGUNAKAN METODE MASW UNTUK WILAYAH YOGYAKARTA

Jurnal Meteorologi dan Geofisika, 2016
Yogyakarta merupakan salah satu wilayah yang aktif gempabumi di Indonesia. Sumber gempabumi dapat berasal dari patahan lokal Opak di bagian timur ataupun zona subduksi pada bagian selatan Yogyakarta. Pembuatan peta mikrozonasi gempa sangat dibutuhkan untuk pertimbangan pembangunan infrastruktur atau bangunan yang tahan terhadap gempabumi.

Empirical estimation of high-frequency ground motion on hard rock [PDF]

, 2016
Site effects for hard-rock sites are typically computed using analytical models for the effect of κ0, the high-frequency attenuation parameter. New datasets that are richer in hard-rock recordings allow us to evaluate the scaling for hard-rock sites (e.g.

Seismic fragility curves of a historical brick masonry minaret

Earthquake Spectra, Volume 41, Issue 5, Page 3499-3525, December 2025.
Historical minarets are generally vulnerable to earthquakes because of their poor‐quality materials and high slenderness. The objective of this work is to utilize the methodology employed for seismic fragility curves to analyze historical brick minarets, specifically focusing on a specific instance minaret.
