Abstract

Based on earthquake history, Gorontalo city is an earthquake-prone region due to its location near active faults, such as the Gorontalo fault, which crosses the Gorontalo City and its vicinity. The last large destructive earthquake occurred on November 8, 1941, with a magnitude of about 7.4, and the epicenter was located in the Gorontalo Fault. This paper estimates the potential ground shaking if the Gorontalo earthquake Mw 7.4 with a hypocenter depth (h) of 10 km were to occur again in the same location. It also analyzes the earthquake return period using the kinematic model and scaling law relationships of earthquake parameters. The earthquake source model is considered as a point source with a strike-slip focal mechanism. The slip rate data for the Gorontalo fault is about 9-12 mm/y. After processing the potential for ground shaking, the Peak Ground Acceleration (PGA), Peak Ground Velocity (PGV), and earthquake return period were estimated to be around VII-IX MMI, 49-56% g, 35-45 cm/s, and 68-200 years, respectively. This assessment aims to support earthquake hazard mitigation and landscape programs in the Gorontalo province.
