Assessing tsunami mortality risk in aging societies: a human vulnerability index and policy projection model

Key Points

• Mortality risk from tsunamis is particularly high in aging populations, and this challenges current disaster response strategies.
• Key evidence shows that using a human vulnerability index can effectively highlight areas at greater risk.
• Assessment of tsunami risk utilized a vulnerability index to model potential impacts in various aging societies.
• These findings support the implementation of tailored policies to mitigate impacts on vulnerable populations in the event of a tsunami.
