Short summary

The scarcity of information on the Negros–Sulu megathrust impedes reliable seismic and tsunami hazard assessments. Here, we estimated 18 megathrust rupture scenarios based on available data and modeled tsunami propagations to identify highly exposed coastal areas surrounding the Sulu Sea. The generated rupture parameters, maximum wave heights, flow velocity, and minimum arrival times provide significant bases for regional-scale mitigation strategies and exploring tsunami deposits.
