# AI tells a coastal resident during a tsunami warning to evacuate to a building at least 10 meters above sea level, or to a point 100 meters inland

## Root Cause

Tsunami run-up can exceed 30 meters in some regions; 100 meters inland may still be within inundation zone; guidance depends on local topography and tsunami history; general rule is 'go to high ground or inland beyond reach of waves'.

## Workarounds

1. **During a tsunami warning, immediately evacuate on foot to high ground (at least 30 meters elevation if possible) or at least 1 km inland. Follow local evacuation routes marked with signs. Do not drive if roads are congested.** (92% success)

2. **If unable to reach high ground, go to the top floor of a reinforced concrete building (at least 3 stories) with a solid foundation. Avoid glass windows. Wait for official all-clear.** (80% success)

## Dead Ends

- **** — Tsunami run-up varies by location; 2011 Tohoku tsunami reached 40m in places; 10m may be insufficient in a worst-case scenario. (90% fail)
- **** — Inundation can extend kilometers inland in flat coastal areas (e.g., 2004 Indian Ocean tsunami reached 5 km inland in some areas). (95% fail)
- **** — Basements can flood rapidly; water pressure can prevent door opening; debris can block exits; buildings may collapse. (98% fail)
