TSUNAMI-EVAC-ERR-006 emergency life_safety ai_generated partial

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

Root Cause

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

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

Workarounds

  1. 82% success 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

Dead Ends

Common approaches that don't work:

  1. 90% fail

    In many coastal cities, high ground is kilometers away; traffic jams or blocked roads make it impossible. Vertical evacuation is faster and safer

  2. 95% fail

    Trees are not structurally sound against tsunami debris and wave force; only reinforced concrete buildings with deep foundations are safe

  3. 85% fail

    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
