Outline
The devastating 2004 Indian Ocean tsunami exposed critical weaknesses in Thailand's tsunami preparedness, particularly in Khao Lak, one of the hardest-hit areas. Despite efforts such as early warning systems and evacuation signage, challenges remain due to population growth, infrastructure deterioration, and limited availability of vertical shelters. This talk highlights the use of an Agent-Based Modeling and Simulation (ABMS) approach, developed with the Unity game engine, to examine evacuation behaviors and identify key factors influencing evacuation effectiveness in Khao Lak. Findings indicate that issues such as inadequate signage, insufficient vertical shelters, reliance on vehicles, and evacuation delays pose significant risks during a tsunami. The study proposes actionable measures, including increasing evacuation signage, utilizing mid-rise reinforced concrete buildings as vertical shelters, promoting on-foot evacuation, and minimizing delays through individual evacuation efforts. These measures aim to enhance evacuation readiness and address vulnerabilities in the current system. While focused on Khao Lak, the simulation tool offers broader applicability, providing valuable insights for improving tsunami preparedness in other coastal areas. By addressing real-world challenges, this approach emphasizes the importance of proactive and targeted measures to reduce tsunami risks and safeguard communities.
