The Purpose of the research was to investigate vulnerability assessment and find the potential of vertical evacuation in the Western Coastal belt in Sri Lanka. The study aimed at achieving two objectives, such as (1) Application of Papathoma Tsunami Vulnerability Assessment model (PTVA) to calculate vulnerability of buildings of the study area; (2) Identification for potential evacuation sites and calculation of the maximum time to reach the selected evacuation sites. During this period, I was able to identify the possible tsunami evacuation centers in study area. The fieldwork was conducted to verify the result of the research. In addition, detailed fieldwork was undertaken to understand the tsunami disasters in North and East parts of Sri Lanka. The discussion was conducted with disaster management center of Sri Lanka to discuss the research outcomes of the Ph.D. research and its future implications.

该研究的目的是调查脆弱性评估并发现斯里兰卡西海岸带垂直疏散的潜力。该研究旨在实现两个目标，例如（1）应用帕帕霍马海啸脆弱性评估模型（PTVA）计算研究区建筑物的脆弱性； (2) 识别潜在的疏散地点并计算到达选定疏散地点的最长时间。在此期间，我能够确定研究区域内可能的海啸疏散中心。进行实地考察是为了验证研究结果。此外，还进行了详细的实地调查，以了解斯里兰卡北部和东部地区的海啸灾害。与斯里兰卡灾害管理中心进行了座谈，讨论了博士生的研究成果。研究及其未来影响。
