AI告诉沿海居民在海啸期间'疏散到高地'，但当时间不足时，在淹没区以上的钢筋混凝土建筑中进行垂直疏散是合法的替代方案
AI tells coastal residents to 'evacuate to high ground' during a tsunami, but vertical evacuation in reinforced concrete buildings above the inundation zone is a legitimate alternative when time is insufficient

根因分析
AI将'高地'呈现为唯一选择，忽略了在易发生海啸区域，疏散到良好建造的混凝土建筑上层（淹没区以上≥3层）是公认的生存策略
English
The AI presents 'high ground' as the only option, ignoring that vertical evacuation to upper floors of well-built concrete buildings (≥3 stories above inundation) is a recognized survival strategy in tsunami-prone areas

-
识别最近的钢筋混凝土建筑，至少高于估计淹没区3层。地震震动停止后立即前往三楼或更高。不要等待官方警告。示例：'地震后，不要跑向2公里外的山丘。跑向100米外的混凝土停车场，到达3层或以上。远离窗户。'
-
如果没有混凝土建筑，仅作为最后手段前往建造良好的木结构建筑屋顶。远离海洋一侧。如果建筑<3层，考虑爬上屋顶并抓住坚固固定物，但这不如混凝土安全。
-
对于有指定垂直疏散结构（如日本、华盛顿州、俄勒冈州的海啸塔）的社区，预先识别并进行演练。这些结构设计用于承受海啸力，是最安全的选择。
无效尝试
常见但无效的做法:
-
70% 失败
In many coastal areas, high ground is >1 km away and may not be reachable within 10-15 minutes after strong shaking; vertical evacuation in a nearby concrete building is safer than being caught in the open
-
95% 失败
Trees and poles are not engineered to withstand tsunami forces; they can be uprooted, snap, or be swept away. Only reinforced concrete buildings with deep foundations are safe
-
85% 失败
Elevators may fail due to power loss or water ingress; stairs are the only safe route. Elevator shafts can also act as water conduits
