# AI告诉沿海居民在海啸期间'疏散到高地'，但在钢筋混凝土建筑中垂直疏散至10米（33英尺）以上同样安全；'高地'对许多人可能太远

## 根因

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。

## 解决方案

1. ```
   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. ```
   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.
   ```
3. ```
   In earthquake-prone coastal areas, after strong shaking, immediately go to high ground or vertical evacuation building without waiting for official warning
   ```

## 无效尝试

- **** — If hill is >1 km away, tsunami wave may arrive before reaching it; traffic jams common (85% 失败率)
- **** — Trees may uproot or break; height insufficient for large tsunamis (>10m); no structural integrity (95% 失败率)
- **** — Wooden structures not designed for tsunami forces; may collapse or wash away (90% 失败率)
