Tsunami risk along Vietnamese coast
Results of the analysis of field survey data and historic literature documents in Vietnam reveal that there is evident of past tsunami attacking Vietnamese coast. However, the evident is still not strong enough to confirm the occurrence of past tsunami events in Vietnam. On the other hand, results o...

Based on the computed results by validated models on the generation of the tsunami by earthquake and the propagation of tsunami in the SCS, it was found that significant tsunami at Vietnamese coast could be generated by an earthquake with magnitude of larger than 7 at the fault along Central Vietnam shelf, and by an earthquake with magnitude of larger than 8 at the Manila Trench. If an earthquake with the magnitude of 7.5 happens at south Hainan Island, the maximum height of tsunami at Vietnamese coast can be more than 1.5m. If the earthquake with magnitude of 8.5 happens at Manila Trench, the maximum tsunami height from Da Nang to Quang Ngai can be more than 4m, and at some places, can be more than 5m.
