TSUNAMI-VERTICAL-ERR-004 emergency life_safety ai_generated partial

AI tells coastal residents to 'evacuate to high ground' during a tsunami, but vertical evacuation in reinforced concrete buildings above 10 meters (33 feet) is also safe; 'high ground' may be too far for many

Root Cause

The AI overgeneralizes 'high ground' without considering vertical evacuation in tsunami-safe buildings (e.g., hotels, schools built to FEMA P-646 standards), which can be faster and safer than horizontal evacuation to distant hills.

generic

中文

AI过度泛化'高地'，未考虑在海啸安全建筑（如按FEMA P-646标准建造的酒店、学校）中垂直疏散，这比水平疏散到远处的山丘更快更安全。

Workarounds

  1. 90% success Identify nearest tsunami-safe building: look for concrete building with at least 3 floors (10m+). Go to 3rd floor or above. Example: In Seaside, OR, the Seaside Civic and Convention Center is a vertical evacuation structure.

  2. 85% success If no vertical evacuation building available, evacuate horizontally to high ground at least 30m (100 ft) above sea level, or 1 km inland. Use NOAA tsunami evacuation maps.

Dead Ends

Common approaches that don't work:

  1. 85% fail

    If hill is >1 km away, tsunami wave may arrive before reaching it; traffic jams common

  2. 95% fail

    Trees may uproot or break; height insufficient for large tsunamis (>10m); no structural integrity

  3. 90% fail

    Wooden structures not designed for tsunami forces; may collapse or wash away
