summaryInvestigation of tsunami sources, capable affecting to the Vietnamese coastBased on the analysis of tectonic feature and geodynamic characteristics of regional faults systems in the South East Asia, nine capable source zones of generating tsunamis that can beaffected to the Vietnamese coast were delineated in the East Vietnam Sea and adjacent sea areas.Statistical methods were applied to estimate the seismic hazard parameters for each source zone, which can be used for the detailed tsunami hazard assessment in the future. Maximum earthquakemagnitudes are predicted for the Manila Trench (8.3 - 8.7), the Sulu Sea (8.0 - 8.4) and the Selebes Sea source zones (8.1 - 8.5) as well. In the East Vietnam Sea region, the Manila Trench source zoneis considered to be the most dangerous to the Vietnamese coast.The estimated Mmax values were used to develop simple scenarios (with a point source assumption) to calculate the tsunami travel time from each source zone to the Vietnamese coast. The results show that for the Manila Trench source zone, tsunamis can hit the Vietnamese coast in two hours at the earliest.
