Project Name
Southeast Asia Hazard
OpenQuake engine input model to perform hazard calculations for Southeast Asia
Description
The most updated open version of the hazard model for Continental Southeast Asia (v2018.0.2) covers Myanmar, Thailand, Vietnam, Laos, Cambodia, Singapore, and West Malaysia. The model was developed by a group of scientists from Singapore, Thailand, Myanmar and Vietnam. It was originally developed in the OpenQuake engine.
Two seismic source models were independently developed by the Earth Observatory of Singapore (Chan et al., in prep) and Mahidol University (Ornthammarath et al., in prep). The two source models are weighted equally in a source model logic tree. The Ground Motion Characterisation for the two models is the same.
Since the original version, several significant updates have been made to the model by the GEM hazard team, leading to the latest release (v2018.1.0), which was used in the computation of the 2023 Global Earthquake Hazard and Risk Maps.
