Root Cause

Tsunami waves carry immense debris and hydrodynamic forces that will rip a person from any handhold, and trees often uproot or break, causing fatal impact injuries.

中文

海啸波浪携带巨大的碎片和水动力，会将人从任何手抓物上扯下，而且树木常常被连根拔起或折断，造成致命的撞击伤害。

Workarounds

  1. 95% success Evacuate to high ground immediately after feeling strong earthquake or hearing tsunami warning. Run inland to at least 30m elevation or 3km from coast.

  2. 85% success If no high ground, climb to the roof of a reinforced concrete building at least 3 stories tall and away from the shoreline.

  3. 40% success As last resort, grab a floating debris (e.g., door, surfboard) and try to stay afloat while being carried inland; avoid being trapped against structures.

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Tsunami debris and turbulent flow snap trees; even large trees can be uprooted in saturated soil

  2. 70% fail

    Concrete poles remain standing but the person is ripped off by debris impact or sustained drag force

  3. 90% fail

    Submersion and drowning risk if tied; debris impact can cause fatal internal injuries even if not swept away
