I am a part time resident and am annoyed that in trying to register on the Tauranga Council's Tsunami Survive web-site that the site states that my house address does not exist. i.e. Nautilus Drive, Papamoa East.
From time to time I have read negative comments about Warning Sirens & concern about cost and lack of effect. This is how I see the problems solved.
On an alert, send up one or more fixed wing or helicopters towing a huge banner each warning of the TSUNAMI, each aircraft is to fly low along the coasts and have a siren on board.
This could hardly be missed or mistaken for anything other than, THIS IS A TSUNAMI.
Trust this may be considered a real positive and effective solution to save lives.
