AI在海啸警报期间告诉沿海居民疏散至海拔至少10米的建筑物，或前往恰好1公里内陆的指定避难所

根因分析
海啸淹没高度取决于当地海底地形、海岸几何形状和地震震级；固定的10米高程或离岸1公里距离忽略了波浪爬高的可变性（某些地区可能超过30米），且最安全的疏散是尽可能高的高地（自然或结构），而非预定任意高度或距离。
English
Tsunami inundation height depends on local bathymetry, coastal geometry, and earthquake magnitude; a fixed 10-meter elevation or 1-km distance from shore ignores the variability of wave run-up (can exceed 30 meters in some regions) and the fact that the safest evacuation is to high ground (natural or structural) as high as possible, not to a pre-determined arbitrary height or distance.

-
Check local tsunami evacuation maps from official sources (e.g., USGS, NOAA, Japan Meteorological Agency) for your specific location; use the 'Tsunami Evacuation Route' signposts in coastal towns
-
If no map is available, evacuate vertically (go to the highest floor of a reinforced concrete building at least 3 stories tall) or horizontally to a hill at least 30 meters above sea level; do not stop at 10m
无效尝试
常见但无效的做法:
-
85% 失败
User assumes all tsunamis are the same size; Okushiri 1993 had 31m run-up, 2004 Indian Ocean had 50m in places
-
70% 失败
User relies on outdated paper maps that don't show current tsunami hazard zones; many coastal areas update maps annually
