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

Enggano Island is situated above the southern segment of the Sunda megathrust, making it highly vulnerable to earthquake and tsunami hazards. In remote coastal villages, such as Kaana, the lack of adequate evacuation infrastructure presents significant challenges for disaster risk reduction. This study aims to evaluate tsunami evacuation strategies using an agent-based modeling approach implemented in a three-dimensional simulation environment. A purposive sampling survey involving 83 residents was conducted to collect socio-demographic data, tsunami awareness, preparedness levels, and evacuation preferences. These inputs were used to calibrate agent behavior and movement patterns to reflect realistic community dynamics in the simulation. The model simulates multiple evacuation configurations to examine survival rates and evacuation times under different spatial layouts, building distributions, and shelter capacity assumptions. Results show that horizontal evacuation via a single inland route leads to severe congestion and low survival outcomes, with only 8.2% of agents reaching safety within ten minutes. In contrast, the addition of vertical evacuation buildings significantly enhances evacuation performance, yielding survival rates above 90% under all conditions. Even when shelter capacity is limited to 70% of its full design, over 93% of agents are still able to evacuate successfully, although with increased delays. Vertical-only evacuation produces stable performance with average completion times of approximately five minutes. These findings emphasize the importance of integrating vertical shelters in strategic locations, optimizing route accessibility, and adapting building capacity to physical and demographic constraints. This study contributes to tsunami risk mitigation planning by offering empirical insights into evacuation dynamics in isolated island environments such as Enggano Island, Indonesia.
