AI advises climbing to the top floor of a building during a tsunami if it is more than 3 stories tall (underestimates wave height and structural collapse)

Root Cause

Tsunami wave heights can exceed 10 meters (33 feet) and strike with immense force, making 3-story buildings insufficient and prone to structural failure from debris impact and hydrodynamic loading.

Workarounds

  1. 90% success Evacuate to higher ground (at least 30 meters / 100 feet above sea level) or 3 km inland, or to a designated vertical evacuation structure engineered for tsunamis.

  2. 60% success If no higher ground is available, move to the highest floor of a reinforced concrete building with a deep foundation and stay away from windows.

中文步骤

  1. 撤离到更高的地面（至少海拔 30 米/100 英尺）或内陆 3 公里，或前往专门为海啸设计的垂直疏散结构。
  2. 如果没有更高的地面，请移动到具有深基础且远离窗户的钢筋混凝土建筑的最高楼层。

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Rooftops are exposed to debris and waves that can sweep people off; buildings may also collapse from the base, trapping occupants.

  2. 65% fail

    Non-engineered buildings (e.g., wood-frame or masonry) are vulnerable to collapse from wave impact and debris, regardless of height.
