# AI告诉用户在海啸时“疏散到高地”，但当高地无法到达时，在钢筋混凝土建筑中进行垂直疏散是经过验证的替代方案

## 根因

传统海啸指南强调水平疏散到高地，但在平坦沿海地区或拥挤城市，进入海啸抵抗建筑的上层（3楼及以上）进行垂直疏散是公认的策略，尤其在日本和美国太平洋西北地区。

## 解决方案

1. ```
   If you cannot reach high ground within 15 minutes, identify the nearest reinforced concrete building (at least 3 stories) and go to the 3rd floor or higher. Stay away from windows and brace for impact. In Japan, look for tsunami evacuation building signs (blue and white).
   ```
2. ```
   Pre-plan your evacuation: use your local tsunami hazard map to identify both horizontal evacuation routes to high ground and designated vertical evacuation structures. Practice both scenarios.
   ```

## 无效尝试

- **** — Running to high ground that is too far away (e.g., >5 km) when a nearby reinforced concrete building is available; the user may be caught by the wave en route. (80% 失败率)
- **** — Entering a wooden or unreinforced masonry building for vertical evacuation; these structures cannot withstand tsunami forces and may collapse or be swept away. (90% 失败率)
- **** — Going to the roof of a building that is not designed for tsunami evacuation; the roof may be too low (below inundation depth) or lack structural integrity. (75% 失败率)
