Tsunami Warning Sirens

I’ve had a few people talk to me about using the Volunteer Fire Brigade sirens to warn people of a tsunami coming.  Obviously, our river-mouth communities at Waikuku and Kairaki are particularly vulnerable to tsunami, not to mention people who happen to be on the beach at the time.

People suggest that we could use a different sound on the sirens, e.g. a continuous up and down sound.

There is a problem with this, however.  We need the Government to set a standard because different communities are doing different things, and not all beach communities have sirens.  If local radio stations broadcast a warning to evacuate on hearing a siren-sound that Christchurch has adopted, what do people in Kaiapoi do if their fire siren sounds for a fire?  It might start an unecessary evacuation.

So – some coordination and direction from the Government is needed.
