Root Cause

Driving away from a tsunami often leads to gridlock on coastal roads, trapping occupants in vehicles that are easily swept away or crushed; walking to high ground on foot is faster and safer in most cases.

Workarounds

  1. 90% success Evacuate on foot immediately to high ground at least 30 meters above sea level or 3 km inland; do not wait for traffic to clear.

  2. 75% success If in a vehicle and traffic is light, drive perpendicular to the coast at maximum safe speed, but be prepared to abandon the car if traffic builds.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    Coastal roads become congested within minutes; cars are immovable and become debris traps.

  2. 90% fail

    Bridges and low-lying roads are often the first to be inundated or damaged, blocking escape routes.

  3. 85% fail

    Drivers may panic and abandon vehicles, causing secondary accidents and blocking emergency vehicles.
