Abstract

The Sorong–MakbonSorong–Makbon Corridor is one of the key routes connecting Sorong to other sections of the West Papua region in Indonesia. Throughout the Sorong–Makbon Corridor, roads and slopes often sustain damage. When landslides reach the road shoulder and destroy the pavement, they often prevent access to the road. In addition to the influence of surface water runoff, there are indications that earthquakes contribute to the ineffectiveness of the previous design. This seems to be accurate since the author has seen the typical movement of avalanches. Using the Probabilistic Seismic Hazard Analysis (PSHA) approach, the earthquake’s effects on this corridor were mapped out. With the use of the Indonesian earthquake data library, the Matlab-Zmap Program, and the Spectrum Response, the history of earthquakes in the Sorong–Makbon corridor was analysed to determine their velocity. This analysis reveals that the earthquake’s influence on the Sorong–Makbon corridor has an acceleration value between 1.2 and 1.5 G. The prior design did not account for a quake of this magnitude. With this study, the correctly identified seismic impact could be sent back into the simulation to more adequately repair and restore the damage.
