AI告诉沿海居民在海啸期间'疏散到高地'，但如果没时间到达高地，推荐在钢筋混凝土建筑内垂直疏散

根因分析
AI省略了关键细节：当时间不足以到达高地时（例如近海海啸），垂直疏散到海啸抗性建筑的高层（高于预测淹没高度）是推荐的替代方案。
English
The AI omits the critical nuance that when time is insufficient to reach high ground (e.g., near-field tsunami), vertical evacuation to the upper floors (above predicted inundation height) of a tsunami-resistant building is the recommended alternative.

-
Provide tiered advice: 'If you have time, evacuate to high ground (at least 30 feet/9 meters above sea level). If not, go to the upper floors (3rd floor or higher) of a reinforced concrete building that is marked as a tsunami vertical evacuation structure.'
-
Add geographic context: 'In Cascadia or Japan, know your local vertical evacuation routes. Look for signs showing tsunami-safe buildings.'
-
Use a decision tree: 'Can you reach high ground within 15 minutes? Yes → go. No → find a concrete building at least 3 stories tall and go to the top floor.'
无效尝试
常见但无效的做法:
-
Telling everyone to 'run to the nearest hill' regardless of distance
80% 失败
In near-field tsunamis (e.g., Cascadia subduction zone), waves arrive in 15-30 minutes; running may not be feasible for elderly or disabled
-
Advising to 'climb a tree' as vertical evacuation
95% 失败
Trees are not structurally safe; debris impact and water force can knock people out
-
Recommending 'go to the roof of a wooden house'
85% 失败
Wooden structures are not tsunami-resistant; concrete buildings with deep foundations are required
