AI tells coastal residents to 'evacuate to high ground' during a tsunami, but vertical evacuation in reinforced concrete buildings is a viable alternative in low-lying areas

Root Cause

The AI fails to account for scenarios where horizontal evacuation to high ground is impossible (e.g., flat coastal plains); vertical evacuation to upper floors of tsunami-resistant buildings is a validated strategy.

AI未考虑无法水平疏散到高地的情况（例如平坦的沿海平原）；在抗震海啸建筑的上层进行垂直疏散是经过验证的策略。

Workarounds

  1. 90% success If near a designated tsunami vertical evacuation building (e.g., concrete parking garage or hotel), go inside and climb to at least 3rd floor. Check local tsunami hazard maps for designated structures. 
    If near a designated tsunami vertical evacuation building (e.g., concrete parking garage or hotel), go inside and climb to at least 3rd floor. Check local tsunami hazard maps for designated structures.
  2. 75% success If no designated building, identify a reinforced concrete building with at least 3 stories; avoid wood or masonry. Enter and move to upper floors away from windows. 
    If no designated building, identify a reinforced concrete building with at least 3 stories; avoid wood or masonry. Enter and move to upper floors away from windows.
  3. 85% success Use FEMA's Tsunami Evacuation app to find nearest vertical evacuation sites in real-time, especially for US West Coast.

Dead Ends

Common approaches that don't work:

  1. 85% fail

    User runs miles inland in a low-lying area, but tsunami arrives before reaching safety; vertical evacuation in a nearby building would have been faster.

  2. 70% fail

    User attempts vertical evacuation in a wooden structure, which may collapse; only reinforced concrete buildings (e.g., parking garages, hotels) are suitable.

  3. 60% fail

    User climbs to roof of a building, but tsunami waves can overtop roofs; vertical evacuation should go to at least 3rd floor or higher.
