Abstract

The Selebar District in Bengkulu City has a high level of earthquake vulnerability due to its location near the Indo-Australian and Eurasian plate subduction zone. This study began with a microtremor survey and earthquake modelling to analyse the seismic response of the soil. Modelling was conducted using the non-linear dynamic Pressure Dependent Hyperbolic (PDH) approach. This method models soil behaviour by considering changes in stiffness and damping due to variations in pressure and strain during an earthquake, thereby providing a more realistic representation of field conditions. The response analysis was conducted in one dimension and produced soil acceleration parameters, with Peak Ground Acceleration (PGA) values ranging from 0.47g to 0.75g. These results indicate a high earthquake potential in the study area. The acceleration spectrum of the input waves increased gradually until it reached its peak at a period of 0.2 seconds, covering the classification range of buildings from low to high. These findings provide essential input for earthquake-resistant infrastructure planning and the formulation of risk mitigation strategies in earthquake-prone areas, such as the Selebar District in Bengkulu City.

Abstract

Kota Bengkulu terletak pada pertemuan antara Lempeng Eurasia dan Lempeng Indo-Australia yang menjadi pertimbangan adanya gempa besar yang mungkin terjadi. Penelitian ini berlokasi di Kecamatan Kampung Melayu. Titik penelitian didominasi oleh tanah pasir dengan klasifikasi tanah keras (SC) dan tanah sedang (SD). Penelitian ini bertujuan untuk menganalisis respon seismik pada daerah yang dianggap berpotensi terganggu menggunakan perbandingan linier ekuivalen dan nonlinier. Analisis respon seismik dilakukan menggunakan metode Pressure Dependent Hyperbolic (PDH) yang menghasilkan parameter tanah berupa Peak Ground Acceleration (PGA), percepatan respon spektra periode panjang 1 detik dan periode pendek 0,2 detik, dan faktor amplifikasi. Penggunaan metode ini memberikan hasil sesuai dengan perilaku tanah. Hasil yang didapat dari penelitian ini menunjukkan linier ekuivalen memiliki nilai yang lebih tinggi jika dibandingkan nilai nonlinier. Permodelan linier ekuivalen menunjukkan terjadi overestimasi yang mempengaruhi nilai percepatan maksimum lebih tinggi dari model nonlinier. Oleh karena itu permodelan nonlinier lebih relevan digunakan dan menggambarkan kondisi lapangan.

Abstract

This study evaluates the susceptibility of soil liquefaction in the coastal area of Bengkulu City. The evaluation was carried out using a probability approach that includes the contribution of all seismic hazard levels that potentially trigger liquefaction, interpreted by the magnitude and maximum acceleration parameters. The soil strength parameters were collected from 26 CPT points spread along the coastal area of Bengkulu City. This evaluation implements the results of the Probabilistic Seismic Hazard Analysis (PSHA) for Bengkulu City, whereas the dominant earthquake source comes from the subduction zone of Sumatra Island. The factor of safety and the probability for each return period of liquefaction. The results of the evaluation in the form of a safety factor and probability in each return period of liquefaction are presented by a spatial model. The results show that in the return period of 475 years, the soil layer to a depth of 1 m is unsafe against liquefaction (the safety factor is less than 1) with a probability value of almost 100%. This indicates that the soil condition of the coastal area of Bengkulu City is very vulnerable to liquefaction during an earthquake. Therefore, planning the structure of houses and roads with a foundation depth of more than 1 m should be recommended to reduce potential damage due to liquefaction.

Abstract

Singaran Pati District, Bengkulu City, is located in an active subduction zone, making it prone to seismic activity. However, to date, there is no detailed microzonation map available to assess local vulnerability to earthquake shocks. This study aims to produce a microzonation map based on shear wave velocity (Vs) and Ground Amplification Factor (GAF) parameters as indicators of soil resistance. Vs values are calculated sequentially at depths of Vs10, Vs20, Vs30, Vs40, and Vs50 using spectral inversion methods. Soil site classification is based on NEHRP standards. Spatial interpolation uses the Inverse Distance Weighting (IDW) method to map parameter distribution. Results show that Vs velocity increases with depth, with a dominance of Class D sites (moderate soil), followed by Class C (very dense soil and soft rock), and a small portion of Class B (moderate rock). The GAF map identifies points with the highest amplification that are at high risk of damage due to earthquakes. The maximum Ground Amplification Factor (GAF) value is shown in red on the map, with a value of 2.0, while the minimum value is shown in green, representing a value of 1.0. This condition indicates that some areas in Singaran Pati Subdistrict have a significant potential for earthquake impact. Therefore, the use of microzonation maps is crucial as a basis for structural building planning and seismic risk mitigation in the Singaran Pati area.

Abstract

The city of Bengkulu is the capital of Bengkulu Province, which is the main center for government, health, and education activities. As the capital city, infrastructure development is important due to its proximity to the subduction zone. This study analyzes how the Tino Galo hospital building responds to seismic performance. The study began with a comprehensive field survey to collect geological information at the study site. Referring to various earthquake events at the study site, it is known that earthquakes triggered by subduction are the dominant type of earthquake that occurs. The seismic response of the soil was then evaluated to identify soil movement characteristics, including important parameters such as peak ground acceleration (PGA), spectral response acceleration, and amplification factor. The next step was to simulate earthquake wave propagation using three-dimensional modeling with the Finite Element Method (FEM) to assess the structural response of the building to earthquake shocks. The analysis results show that after evaluation using time history data from both earthquake waves, the building structure elements are in a safe condition. These findings imply that the current structural design can effectively withstand and distribute earthquake loads, so that no dimensional changes or additional reinforcement are required for the Hospital Building. This study recommends the continued application of a combined soil response and structural dynamics analysis method for buildings in earthquake-prone zones, as well as the need to utilise a broader range of earthquake data to improve the accuracy of seismic performance evaluations and support the development of future risk mitigation strategies.

Abstract

The downstream area of the Muara Bangkahulu River is a developing area in Bengkulu City that was affected by major earthquakes in 2000 and 2007. The risk of earthquake-induced damage in this area requires further investigation, particularly regarding soil resistance to seismic shaking. This study aims to analyze soil characteristics based on shear wave velocity (VS), site classification, and Ground Amplification Factor (GAF) to support earthquake-resistant infrastructure planning. This study uses microtremor data inversion methods conducted at 38 measurement points. Shear wave velocity (VS) data at depths of 10–50 m were analyzed to determine site classes and Ground Amplification Factor (GAF). Data processing was performed using surface wave inversion techniques to map VS distribution and seismic amplification. The results of the study show that VS values at depths of 10–50 m vary between 160–960 m/s, with site class classifications dominated by categories C (hard soil) and D (medium soil). The Ground Amplification Factor (GAF) values ranged from 1.1–1.9, with areas of high amplification indicating greater vulnerability to earthquake shocks. These findings serve as an important reference for disaster mitigation planning and earthquake-resistant infrastructure development in the region. Technical recommendations are needed for locations with high amplification to minimize the risk of earthquake damage in the future.

Abstract

Kabupaten Bantul merupakan wilayah dengan tingkat kerentanan gempa yang tinggi akibat aktivitas tektonik zona subduksi di selatan Pulau Jawa, sehingga analisis respon seismik berbasis kondisi tanah lokal menjadi penting untuk mendukung perencanaan struktur tahan gempa. Penelitian ini bertujuan untuk menganalisis respon seismik nonlinier tanah akibat Gempa Bantul 2023 melalui parameter Peak Ground Acceleration (PGA), percepatan respon spektra, dan faktor amplifikasi. Metodologi penelitian menggunakan model atenuasi NGA-Subduction untuk menghasilkan percepatan spektral sebagai target spectral matching, yang selanjutnya digunakan sebagai input motion dalam analisis respon tanah satu dimensi nonlinier menggunakan perangkat lunak DeepSoil Versi 7. Data tanah diperoleh dari hasil Standard Penetration Test (SPT) pada empat titik penelitian, serta klasifikasi kelas situs ditentukan berdasarkan nilai Vs30. Hasil penelitian menunjukkan nilai Vs30 berkisar antara 259–412 m/s dengan dominasi kelas situs D dan satu titik kelas C, nilai PGA permukaan sebesar 0,047–0,063 g, serta faktor amplifikasi antara 0,91–1,25. Respon spektra di permukaan umumnya meningkat pada periode pendek dibandingkan input motion, namun masih berada di bawah spektra desain SNI 1726:2019. Penelitian ini menyimpulkan bahwa kondisi tanah lokal berperan signifikan dalam memodifikasi respon gempa dan berkontribusi dalam pengembangan analisis bahaya seismik berbasis lokasi spesifik

Abstract

This study aims to evaluate and map earthquake-induced liquefaction potential in Kandang and Temdak Villages, Seberang Musi District, Kepahiang Regency. The analysis integrates geotechnical and seismic parameters, including peak ground acceleration, shear wave velocity, earthquake intensity, and soil vulnerability index. The results indicate that the study area is dominated by high ground acceleration and strong to very strong shaking intensity, which act as the main triggering factors of liquefaction. The evaluation of subsurface conditions shows that liquefaction potential mainly occurs in shallow layers composed of loose and saturated soils, while deeper layers tend to be more stable. The liquefaction potential index values vary significantly, ranging from low to very high across different locations. The highest value reaches 76.04, indicating very high liquefaction potential, while the lowest value is approximately 4.45, indicating lower potential. These findings suggest that the thickness and dominance of vulnerable layers at shallow to intermediate depths are the main factors controlling liquefaction potential. Overall, the applied approach provides a representative assessment for identifying liquefaction-prone zones and supports earthquake risk mitigation planning in the study area.
