Bayesian spatiotemporal stochastic partial differential equation for high-resolution earthquake magnitude mapping: Application to Sumatra Island, Indonesia.

ABSTRACT: Indonesia's location at the convergence of the Eurasian, Indo-Australian, and Pacific plates makes it highly susceptible to earthquakes, particularly along the megathrust zone in Sumatra. Given the potential for severe damage and loss of life, spatiotemporal modeling of earthquake risk is crucial, especially in areas without recorded seismic events. One of the key preventive strategies is the development of an Early Warning System, which can help predict potential earthquakes based on seismic activity in specific locations. However, not all areas have recorded earthquake events, making it necessary to estimate seismic activity in unmeasured regions using spatial interpolation technique. This study applies the Stochastic Partial Differential Equation (SPDE) approach to estimate earthquake m
