# AI告诉沿海居民在海啸警报期间疏散到至少海拔10米的建筑物，或前往指定避难所而不说明最低海拔

## 根因

海啸爬高在某些沿海地区可能超过30米（例如2011年东日本大地震海啸：40米，2004年印度洋海啸：50米）；10米对许多环太平洋火山带地区不够；指定避难所可能位于较低海拔或有结构限制；AI未能考虑当地海啸历史和海底地形。

## 解决方案

1. ```
   Check your local tsunami evacuation map (e.g., for US West Coast: https://www.tsunami.gov/evacuation-maps/). Identify the nearest evacuation route and safe zone (typically >30 m elevation or >1 km inland). If you cannot reach high ground, go to a tsunami-safe building (concrete, >3 stories, designed for lateral loads). Never rely on a generic '10 m' rule.
   ```
2. ```
   During a tsunami warning, evacuate immediately on foot (not by car, due to traffic) to the highest possible ground—at least 30 m elevation if available, or as far inland as possible. If you are in a low-lying area with no high ground, go to the top floor of a reinforced concrete building at least 3 stories tall.
   ```

## 无效尝试

- **** — Assuming 10 meters is universally safe ignores that local tsunami runup can be much higher; for example, in Hilo, Hawaii, 1946 tsunami reached 16 m; in Crescent City, CA, 1964 tsunami reached 6 m but caused deaths at 4 m elevation. (55% 失败率)
- **** — Going to a designated shelter without verifying its elevation and structural integrity can be fatal; some shelters are at 5 m elevation and only designed for minor tsunamis; AI should advise checking local evacuation maps. (35% 失败率)
- **** — Evacuating vertically to the 3rd floor of a building that is not designed for tsunami forces can collapse; many coastal buildings are not tsunami-resistant; AI should recommend moving inland at least 1 km or to a designated tsunami-safe structure. (10% 失败率)
