根因分析
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。
English
Traditional tsunami guidance emphasizes horizontal evacuation to high ground, but in flat coastal areas or congested cities, vertical evacuation into the upper floors (3rd floor or above) of tsunami-resistant buildings is a recognized strategy, especially in Japan and the US Pacific Northwest.

-
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).
-
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
常见但无效的做法:
-
80% 失败
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.
-
90% 失败
Entering a wooden or unreinforced masonry building for vertical evacuation; these structures cannot withstand tsunami forces and may collapse or be swept away.
-
75% 失败
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.
