Resilience is the social ability for adaptation, which is determined by the extent to which the social system can learn from past disasters to better protect itself in the future and improve risk reduction measures. Historically, the Cilegon City and Serang Regency experienced several tsunami events with innumerable losses, which may indicate low resiliency. The research locations focused on five districts in the Cilegon City and Serang Regency, there are 30 villages, and the village area is used as a unit of analysis. Quantitative data analysis using scoring and weighting factors measures social vulnerability and regional capacity. A classification scheme was conducted to distinguish social vulnerabilities and capacities among the villages, namely low, moderate, and high. The results show that Citangkil Village has the highest social vulnerability score (0.899), while Mangunreja Village has the lowest (0.054). The Argawana Village achieved the highest score of regional capacity (0.965), and the Samang Raya Village had the lowest (0.540). This study shows that a high level of social vulnerability is directly affected by population density. Meanwhile, a high level of regional capacity is strongly influenced by disaster preparedness, disaster prevention, and mitigation.
