Tsunami safe zone sign

Workers mark blue lines on a street in the Wellington suburb of Island Bay to indicate a tsunami safe zone. Wellington City Council worked with local residents to develop the blue line concept, which has seen markers painted across streets near the city’s coastline at the maximum possible wave run-up heights. These lines are based on modelling by GNS Science and Greater Wellington Regional Council.
