Root Cause

Holding onto a tree or pole during a tsunami is impossible due to the force of water and debris, which can crush or sever limbs, and the structure may be uprooted or collapse.

在海啸中抓住树木或杆子是不可能的，因为水流和碎片的冲击力巨大，可能压碎或切断肢体，而且树木或杆子可能被连根拔起或倒塌。

Workarounds

  1. 95% success Immediately evacuate to high ground or inland, at least 100 feet above sea level or 2 miles from the coast. If no high ground, climb a reinforced concrete building to at least the 3rd floor.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    People believe trees provide sturdy anchorage, but tsunami water can uproot even large trees, and debris like cars or logs can impact the person.

  2. 90% fail

    Some think wrapping arms around a pole will prevent being swept away, but water pressure and floating debris cause loss of grip within seconds.
