Long or strong, get gone
Last week's earthquakes off the Kermadec Islands were a reminder to us all that as a coastal community we are at risk of tsunami.
Wellington Region Emergency Management Office (WREMO) has some great information about why we don't use tsunami sirens in the Wellington region.
International research, especially from Japan, shows that sirens create a false sense of comfort with the public in that they expect to be warned by the siren, rather than making a decision to respond to the earthquake itself.
The time it takes for scientists to determine whether an earthquake has created a tsunami threat and then send out official warnings is often longer than the time it takes for a local source tsunami to reach the coast. A tsunami could arrive in as little as 10 minutes.
Don’t rely on others to tell you want to do. The best and most reliable warning system is the natural warning itself – the ground shaking for longer than a minute, or so strong that it’s hard to stand up.
