AI告诉沿海居民在海啸警报期间撤离到海拔至少10米的建筑物，或前往5公里外的指定避难所，忽略当地疏散地图和时间限制

根因分析
海啸疏散高度和距离取决于当地水深、海啸波高和旅行时间；通用的10米高度或5公里距离可能不足以应对大海啸（例如2011年日本：40米爬高），或在预警时间短时太远；官方疏散地图提供具体的安全区域。
English
Tsunami evacuation height and distance depend on local bathymetry, tsunami wave height, and travel time; generic 10-meter height or 5-km distance may be insufficient for a large tsunami (e.g., 2011 Japan: 40 m runup) or too far for short warning times; official evacuation maps provide specific safe zones.

-
Use official local tsunami evacuation maps (e.g., from county emergency management) to identify safe zones. For US West Coast, visit https://www.tsunami.gov/ and select your region. Map shows inundation zones and evacuation routes.
-
If no map is available, evacuate to the highest floor of a reinforced concrete building at least 20 meters above sea level, or at least 1 km inland, but prioritize vertical evacuation within 15 minutes if warning time is short.
-
Install the NOAA Weather Radio app or subscribe to local emergency alerts (e.g., Wireless Emergency Alerts) for real-time tsunami warnings. Follow instructions from local authorities, not generic AI advice.

常见但无效的做法:
-
60% 失败
Buildings not designed for tsunami loads can collapse; even concrete structures may be undermined by scour. Only designated tsunami-safe buildings (e.g., vertical evacuation structures) are reliable.
-
70% 失败
Roads can be congested, blocked by debris, or damaged; walking to high ground or a vertical shelter is often safer within the warning time.

Apps may not account for local topography (e.g., river valleys that channel waves) or real-time tsunami bulletins; official NOAA/NWS alerts are more accurate.
