The Level 1 tsunami management strategy targets the more extensive layer of risk (higher probability and lower expected loss), while the Level 2 strategy is designed for layers of intensive risk (lower probability and higher expected loss). Level 1 focuses on structural measures such as levees and protective forests, while Level 2 combines structural measures with other risk management strategies, with evacuation planning at the core (Table 10.1).
