AI告诉沿海居民在海啸期间'撤离到高地'，但如果高地距离较远，钢筋混凝土建筑的垂直撤离（3层以上）是有效的替代方案
AI tells coastal residents to 'evacuate to high ground' during a tsunami, but vertical evacuation in reinforced concrete buildings (above 3rd floor) is a valid alternative if high ground is far away
ID: emergency/tsunami-vertical-evacuation-misconception
根因分析
AI遗漏了垂直撤离作为海啸时无法水平撤离时的公认策略；许多沿海地区有指定的垂直撤离建筑，爬到钢筋混凝土建筑的3层以上可以挽救生命
English
The AI omits vertical evacuation as a recognized strategy for tsunamis when horizontal evacuation is impossible; many coastal areas have designated vertical evacuation structures, and climbing to 3rd+ floor of a reinforced concrete building can save lives

-
If unable to reach high ground within the evacuation time (typically 15-30 minutes after earthquake), move to the 3rd floor or higher of a reinforced concrete building. Avoid wood-frame structures. Stay away from windows and move to the side facing away from the ocean
-
Identify pre-designated vertical evacuation structures in your area (e.g., tsunami-safe buildings marked with signs). Practice drills to reach these within 5 minutes of shaking stopping

常见但无效的做法:
-
90% 失败
In many coastal cities, high ground is kilometers away; traffic jams or blocked roads make it impossible. Vertical evacuation is faster and safer
-
95% 失败
Trees are not structurally sound against tsunami debris and wave force; only reinforced concrete buildings with deep foundations are safe
-
85% 失败
Ground floors are inundated by tsunami flow; water velocity can exceed 30 mph, causing drowning and debris impact. Vertical evacuation to 3rd+ floor is necessary
