Abstract

This study investigates the tsunami hazard potential induced by the activity of the South Buru Thrust Fault on the coastal areas of Ambon City through two-dimensional (2D) numerical modelling using the COMCOT v1.7 software, while incorporating three-dimensional (3D) slip evolution from the fault scenario. The earthquake scenario was set at Mw 8.3 based on fault length, width, and slip potential estimates, representing an extreme seismic event in the region. By integrating 3D slip evolution into the 2D tsunami model, the approach accounts for spatial variations in vertical displacement along the fault plane, directly influencing tsunami generation and propagation. The simulation results show significant spatial variations in tsunami run-up heights and inundation zones, with maximum run-up recorded at Kapahaha (13.08 m, arrival time ~832 s) and Slamet Riyadi Port (12.02 m, arrival time ~786 s). In comparison, minimum values occurred in Ambon's northern and northeastern parts (<1 m). The affected area and inundation distance from the shoreline also vary, e.g., Kapahaha (12,813 m², 159 m) and Slamet Riyadi Port (414,158 m², 1,213 m). Areas experiencing the highest tsunami inundation are Latuhalat (>5 m), followed by Galala–Wayame–Laha (3–5 m) and Paso–Rumah Tiga–Hative Kecil (2–4 m). The distribution of tsunami waves is influenced by coastal morphology, wave direction, and the presence of bays and capes, which can either amplify or block waves. Further analysis highlights the effects of seafloor topography, coastal morphology, and wave propagation pathways on run-up heights and arrival times. These findings underscore the importance of considering multi-segment rupture models, 3D deformation, and coastal morphology in tsunami hazard assessments and contribute to more realistic, source-specific mitigation strategies in tectonically complex regions such as Ambon.

Abstract

The research has measured the landslide using a displacement sensor based on Glass Optical Fiber (GOF) and Optical Time Domain Reflectometer (OTDR). The sensor manufacture process consists of various materials, structures, configurations, diameters, and directions. The sensor is made using GOF with a single-mode structure and single mode-multimode-Singlemode (SMS) structure. Each system is given a variety of configurations, namely gamma, bowknot, and three loops configuration. Each arrangement is provided a variation of the indentation diameter in three displacement directions. The test results will be read as the power loss on the OTDR in dB units. The results obtained were then compared between two materials, two structures, and directions. Displacement resulting landslides and changes to the sensor, causing power losses, and affecting the characteristics of each sensor. We found the best measurement results with the sensitivity value of 0.241 dB/mm and the resolution value of 0.004 mm. The displacement sensor has been made for measuring landslide in the laboratory-scale simulation based on GOF and OTDR with easier fabrication, easy operation, high sensitivity, better resolution and can be connected to a computer
