Goal and objectives of the project

- Development of the near-field and far-field tsunami scenarios for earthquake information and tsunami warning purposes
- Capacity building for Earthquake Information and Tsunami Warning Center, Institute of Geophysics, Vietnam Academy of Science and Technology

 

Main results

Theoretical results:
- Built a background database for the study area.
- Built a 1002 tsunami scenarios database;
- Built a pre-calculated tsunami scenarios database and a DSS for tsunami early warning;
- Proposed tsunami response plans for coastal communities and appropriate prevention solutions.
Applied results:
- The digital databases built within the framework of the topic are good sources for further research. In particular, the pre-calculated tsunami scenarios database will be used in the tsunami early warning in Vietnam.

 

Novelty and actuality and scientific meaningfulness of the results

- Established a unified scaling law for earthquakes in Vietnam for both long-term and short-term seismic activities, allowing to link both Gutenberg-Richter's law, the Omori's law decay of triggered earthquakes and the fractal dimension faults.
- Determining the lower bound magnitude value M = 4.0 is suitable for assessing seismic hazards in Vietnam.

Recommendations

 In the framework of the research project, it only stops at assessing the tsunami hazard based on scenarios, or in other words, this is a deterministic approach in tsunami research. Therefore, it is necessary to conduct a study on tsunami hazard assessment by the probabilistic method to have a comprehensive view of the tsunami hazard in Vietnam. The next step is to conduct a tsunami risk assessment and zoning for response and damage mitigation.
