What do they plan to do regarding emergency radio broadcasting in auckland if a tsunami hit? the base of both radio towers in west auckland are only a few metres above sea-level, and the sky tower where all the fm are is only about 20m but being close to the harbour is probably more exposed. Im assuming there is a backup facility in place at the Waiatarua tv tower atleast for fm?

Is the harbour even at risk of Tsunami? I thought it was pretty well sheltered? Plus, there's quite a lot of other buildings between the sky tower and the water to buffer any significant waves, even ones 20M high. Lol Sam, Auckland Skype: tardtasticx

Hi Guys, With Tsunami and other Hazards for Auckland best place is to head over to http://www.aucklandcivildefence.org.nz/ or http://www.arc.govt.nz/council/civil-defence-emergency-management/natural-hazards/tsunami.cfm and check out what they have. I also know that there is warning systems (Sirens) in place for a lot of Auckland too that will be activated if there is a risk. When you are saying about these size waves are you referring to a Distant Source Tsunami (one from the other side of the pacific) or one created closer to NZ? If you are talking about Distant Source Tsunami's then for NZ we have 12+ Hours notice of these and will know wave heights as it gets closer to us. Unsure where you are getting 20m waves from though as the biggest modeling that our Scientists can model is well under that figure. If you are talking about Regional / Local Source Tsunami then for Auckland it will all depend on where its is centered, Part of the Kerepehi Fault is located in the Firth of Thames, Hauraki Gulf, New Zealand. If sufficient movement occurs along the submarine section of this fault, a tsunami could be generated. Fault movement is thought this is likely to occur every 4,500-9,000 years or so. A tsunami generated by this mechanism could reach up to 3 m above mean sea level.

wouldn't it be the surge as well that would push the water inland, eg a 3m wave but with a lot of force behind it is going to drive it inland. Im just interested to see if they have some sort of a backup in place for emergency broadcasts should the sky tower be out of action and other transmission facilities aswell. Im assuming worst case scenario a mobile broadcast unit would have to operate.

I cannot talk from Auckland City and Auckland City - Civil Defence Emergency Management but I'm sure they do have other plans in place. Also the Warning System is run from their Emergency Operations Centres and is on its own system to operate them.

Genfres: so does this mean we shouldn't worry about this? Not saying that at ALL, it is something all New Zealanders should be well aware of is Tsunamis and all other hazards around us We do live in a very active part of the world when it comes to Natural Disasters. If you need information about being prepared for a disaster then http://www.getthru.govt.nz/ is your best site for information

Great warning system we have.

If the sky tower gets knocked out, so does a lot of internets!
