Yangon, facing future earthquake risks caused by Sagaing Fault, must implement earthquake risk reduction measures in future development. This paper analyzes relationship between ground conditions and urban expansion of the city, and assesses regional vulnerability based on building damage estimation due to huge earthquakes. Then, it clarified as follows: (1) Yangon has expanded even on soft ground areas since the middle of the 20th century, (2) approximately 85% of buildings will be completely damaged in the worst scenario, and (3) as a result of relative evaluation for each ward, areas in the eastern suburbs are more vulnerable in most cases.
