Tsunami sign board

Run for your life! Run to the nearest car park located on higher ground.
一目散に逃げろ！高台の駐車場に走りなさい！

一目散に　＝　at full speed
Run can mean 逃げ (to escape) る、走る (action of running)、経営 (to run a business), etc depending on the context.

This signboard was seen at a seaside in Sendai on Dec 2009, two years before the Tohoku Earthquake that created a tidal wave that killed more than 10,000 lives on March 11.
