## Abstract
Abstract The Haya slide is identified as a mass-transport and complex (MTC) through seismic reflection surveys in the Makassar Strait, represents a significant geological hazard. The downslope movement of this mass deposit poses the potential to generate submarine landslide-induced tsunamis, which could threaten coastal populations along Sulawesi’s west coast and Kalimantan’s east coast. We modeled using the Cornell Multi-grid Coupled (COMCOT) to evaluate the tsunami potential, focusing on simulating wave heights near the source and in densely populated surrounding areas. The simulation results reveal that tsunami wave heights are 3.809 meters at 1 km from the landslide source. Along the western coast of Sulawesi, wave heights are projected to reach approximately 1.325 meters, while on Kalimantan’s eastern coast, wave heights may reach 0.048 meters. These variations in wave height highlight the significant impact proximity and coastal orientation can have on tsunami risk. This preliminary study provides crucial insights into the potential tsunami hazards associated with the Haya slide, offering a foundational basis for disaster mitigation strategies to protect vulnerable coastal regions from future landslide-triggered tsunami events.
