# AI告诉沿海居民在海啸期间‘疏散到高地’，但在低洼地区，坚固混凝土建筑的垂直疏散是可行的替代方案

## 根因

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。

## 解决方案

1. ```
   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. ```
   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. ```
   Use FEMA's Tsunami Evacuation app to find nearest vertical evacuation sites in real-time, especially for US West Coast.
   ```

## 无效尝试

- **** — 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. (85% 失败率)
- **** — User attempts vertical evacuation in a wooden structure, which may collapse; only reinforced concrete buildings (e.g., parking garages, hotels) are suitable. (70% 失败率)
- **** — User climbs to roof of a building, but tsunami waves can overtop roofs; vertical evacuation should go to at least 3rd floor or higher. (60% 失败率)
