Abstract

This study aims to separate regional and residual components from complete Bouguer anomaly data using the Gaussian Low Pass Filter method in the geothermal prospect area of Way Ratai, Lampung. Spectral analysis was applied to determine the optimal cutoff frequency that distinguishes regional, residual, and noise components. The spectrum analysis identified three linear segments with R² values of 0.8332 (regional), 0.9655 (residual), and 0.9518 (noise), supporting the accuracy of the segmentation. The complete Bouguer anomaly map displays a decreasing gravity trend towards the northeast, indicating large-scale subsurface density variations. After filtering, the regional anomaly map shows smooth contours reflecting broader geological structures, while the residual anomaly map reveals sharper local features such as faults and fractures, which are potential geothermal fluid pathways. These results demonstrate the effectiveness of the Gaussian Low Pass Filter in enhancing geophysical resolution and geological interpretation for geothermal exploration.

Abstract

Background: Bandar Lampung is situated in a seismically active region influenced by the subduction of the Indo-Australian and Eurasian plates, which increases its susceptibility to earthquake hazards. This study aims to evaluate the level of earthquake vulnerability and formulate appropriate mitigation strategies using a spatial and SWOT-based approach. Methods: The methods applied include historical earthquake data analysis, hazard zone mapping, spatial analysis through Geographic Information Systems (GIS), and a review of existing disaster mitigation policies. Findings: The results indicate that during March 2024, 146 earthquake events were recorded, of which 135 were shallow (<60 km) and mainly concentrated in the subduction zone southwest of Lampung. Vulnerability and population density mapping further identified Kedaton, Rajabasa, and Tanjung Karang Pusat as high-risk districts. Conclusion: Based on these findings, recommended mitigation strategies include the enforcement of earthquake-resistant building codes, integration of risk-based considerations into spatial planning, the development of public education and awareness programs, and the strengthening of early warning systems. The study highlights that a spatially informed and policy-oriented approach can effectively reduce the potential impacts of earthquakes and enhance community resilience in Bandar Lampung City. Novelty/Originality of this article: The novelty lies in combining spatial analysis, vulnerability mapping, and a SWOT-based policy framework to produce integrated and location-specific earthquake mitigation strategies for Bandar Lampung City.
