A week long training workshop on probabilistic seismic hazard assessment (PSHA) was arranged during the period June 30 – July 4 2014, in Nay Pyi Taw at Multi-hazard and Early Warning Center of the Department of Meteorology and Hydrology (DMH) under the Ministry of Transport of the Government of Myanmar. The workshop was jointly arranged by the Asian Disaster Preparedness Centre (ADPC), Bangkok in Thailand and the Department of Earth Science, University of Bergen in Norway, and was hosted by the DMH in Nay Pyi Taw, Myanmar. In total, 23 participants attended the workshop (Fig.1). The first two days of the workshop was dedicated to lectures given by the instructors outlining the background, methodology and basic principles of conducting a probabilistic seismic hazard analysis and seismic risk. The remaining three days of the workshop was used to conduct the PSHA computations with hands on exercises specifically designed for Myanmar region.

Participants were divided into six groups where each group worked independently (Fig.2) on the various stages of the probabilistic seismic hazard analyses. After the completion of the analyses, each group has presented their final results in the form of probabilistic seismic hazard maps for Myanmar. Each group has successfully completed the exercises and conducted the hazard computations. As such the main goal of the workshop, which was to conduct seismic hazard computations by the participants, was achieved. Naturally, due to the short time allocated for the workshop, the results of the seismic hazard computations conducted by different groups showed variations. These variations are discusses during the last day of the workshop, where resulting seismic hazard maps from the six groups were compared to each other. Results from each group were critically discussed by the other groups collectively. This has helped to highlight the uncertainties in the input data, as well as the limitations in the chosen methodologies and the choices that had to be made by each group at various stages of the analyses. Finally, all the results were then compared to the existing probabilistic seismic hazard maps prepared by the Myanmar Earthquake Committee of the Myanmar Engineering Society.

Each participant were given a certificate of completion, confirming that they have satisfactorily conducted the exercises for the probabilistic seismic hazard computations during the Myanmar Seismic Hazard Training Workshop held during the June 30 – July 4, 2014 in Nay Pyi Taw (Fig.3).
