Tsunami alert: Latest updates

3pm: Disturbed currents and surges are likely to continue to affect the Southland coastline for several hours, the region's group controller cautions. Southland steps down its tsunami response to a monitoring level.

12:10pm: Dunedin police say people in low-lying coastal areas may be required to evacuate later today.

"Information suggests that it's possible that larger waves may hit the coast over the coming hours. The police want to ensure people will be safe rather than sorry, and ask that they take sensible precautions," said Dunedin Emergency Response Commander, Inspector Alastair Dickie.

10.50am: Otago Civil Defence issues alert saying "current national modelling information indicates the risk to the Otago coastline of a wave height of less than 1m". However, strong currents and unusual tidal effects may continue over the next 12 hours.

10am: The Southland Civil Defence Emergency Management Group has activated the emergency operations centre but says any tidal change for Southland will be non destructive.

All residents are urged to stay off the beaches and out of the water until advised that the risk of a tsunami and strong currents has passed.

8am: Dunedin Civil defence chief Neil Brown tells the Otago Daily Times there is no threat to the city after a massive earthquake in Chile triggered Pacific tsunami warnings.

"I would be very surprised if anything was noted on the shoreline here. From very early on it was obvious the risk  to Dunedin was nil," Mr Brown said.

Tsunami alert: more than one ball dropped

This was not the only aspect of the tsunami alert in which “the ball was dropped”. Another, perhaps more serious lapse, was the inconsistency in the stances of civil defence and the police. Early on Sunday morning Neil Brown told the media that the tsunami posed no risk to Dunedin. A few hours later the Dunedin police were advising that people living in low-lying areas may need to be evacuated (see http://www.odt.co.nz/news/dunedin/95499/tsunami-alert-latest-updates).
During a tsunami alert the provision of timely, widely broadcast, accessible and dependable information is vital. Our most reliable sources of this are civil defence and the police. Any significant discrepancy between these two sources in the advice given during an alert carries a high potential for creating dangerous confusion and certainly represents a major deficiency in our current local systems.
We got away with it this time – in the short-term. Taking a longer perspective, the community’s trust in civil defence and the police during an emergency has been dented. This should never happen again, and we need to know precisely how the discrepancy in advice arose and exactly how the problem is being fixed.

Facebook newsfeed

I wasn't the only one that found out about the tsunami warning via Facebook . . . Then quickly informing myself using a news website (as TV 1 was between broadcasts). I don't believe that the warnings were effective. I think if we are 'on hold' for a natural disaster the town sirens should go off for a couple of seconds every half hour. If I hadn't turned my computer on, and even less likely, my TV. Radio - I dont even own one. I would have had a clue I was at risk til later that evening... too late.

Tsunami communication problem?

At 8.00 am the Dunedin head of Civil Defence is reported as saying that from very early on it was obvious the risk to Dunedin was nil. Just over four hours later Dunedin police are reported as saying that people in low-lying coastal areas may be required to evacuate later in the day. Do the police and civil defence have a serious communication problem?
