Title

Prior Estimation Using ShakeMap for Bayesian Statistical Modelling of Historical Indonesian Seismicity

Abstract

Tsunami caused by earthquake can be deadly and we are interested in the reverse problem of inferring the earthquake from tsunami using Markov Chain Monte Carlo (MCMC) as a Bayesian framework. A ShakeMap is a representation of ground shaking produced by an earthquake. Historical records are incomplete and pose great challenge for accurate shakemaps generation. We improve the accuracy of MCMC using the shakemaps as prior distribution.
