Joint Research for Seismic Hazard Map in Myanmar

Project Gist

Start from knowing the nature in order to prepare for earthquake disaster

Keywords

Strong motion, Underground structure, Microtremors, Building damage

Background, Purpose, and Project Achievements

In Myanmar long active faults are running through its territory that are potentially dangerous for future disasters, however, sufficient countermeasures have not been implemented yet. We conducted joint research activities for constructing a national seismic hazard map, in which we can show probability of occurrence that exceed a certain intensity of ground motion. We performed jointly microtremor surveys and earthquake observations to delineate underground structures and grasp the characteristics of seismic motions.

Future Prospects

We would like to increase numbers of microtremor survey sites and earthquake observation sites in order to more precisely determine the whole basin responses of several major cities in Myanmar. We also conduct active fault surveys and source generation studies to pursue the road of better hazard map construction.
