I was head down bottom up in the middle of writing a complex email,

When all the phones in the office went off simultaneously, I thought it was the fire alarm.

Grabbed my traveller coffee mug, and bolted to the fire escape...

And pulled up short after a couple of steps... oh.. not a fire alarm...

My adjacent colleague dined out on that, " fastest I've ever moved" was the snarky comment..

He'll keep ...

Did everyone get the warning?

I live right on New Brighton beach and got no warning message.

Yet I heard my friend in Woolston receive it, and my friend in Lyttelton asked if I was okay because they got it. I've got an iPhone on Spark.

No police on way home so I'm assuming it's a useless warning.

Ergh just got another CD warning?? Are they being too cautious due to other recent events? I see that other countries have downgraded or cancelled warnings and many reports in other countries that observed effects were less than feared.

Just got alert now (6:30AM).

Presumably sirens went off yesterday? Or maybe they will go off when wave arrives?

RNZ Live:

6:25 AM: NEMA in its latest update a short time ago says tsunami activity has already reached parts of New Zealand. The first currents and surges are unlikely to be the largest and are expected to continue over many hours.

Seems pretty irresponsible to be sending out yet the same alert when situation hasn't changed from what they sent yesterday. Why was it sent at 6:30am, not sure a large portion of the population needed to be woken up?

No immediate action was required. There was no greater risk than when it was sent yesterday afternoon.

Civil Defence need to do a full review of their misuse of this system.

We then look at their posts on X yesterday which are equally poorly managed. Noting the first assessments were based on the inital 8.0, before it was upgraded, but earthquakee always seem to get changed.

The first message was suitable, we're assessing. Then saying there was NO threat around 15 minutes later is unacceptable. The basic maths shows any wave would have been 12+ hours away after the message saying nothing to worry about, they had ample time to consider and assess the risk and threat before there was any threat or action was taken. This is also compounded by the message saying nothing to worry about arriving during a normalish 12-1pm lunch break, so many would have read about the quake, seen NZ media picking up CD saying no alert and carried on with their day...

We then get this message 40 minutes later, saying we're re-assessing. Then 17 minutes later an advisory is issued.

I thought my phones had reset themselves or something when it came through again this morning on all of them!

I get that it’s an emergency and I’d appreciate if I lived in Japan or close to where it happened, but they’ve sent out these alerts as if the tsunami’s going across the pacific to get here. More of a nuisance than an emergency if anything.

We live on the opposite side of Christchurch to the sea and none of our phones have received any alerts.

We did get the alerts last week for the missing elderly lady, so our phones are functioning.

Not sure I follow you … the Indian Ocean tsunami of 2004 killed over 200,000 people across 13 countries.

(Very basic level) Fill your bath with water. Drop a stone in it close to one side. Ripple effect. Just because where you dropped the stone is on the other side of the bath does not mean any part of your bath avoids the ripple.

I'm happy to know that "ripple" could be on its way, rather than have no notification and be out on a boat and have it come along, causing the boat to flip....

I will now be automating my phone to go to airplane mode when at home instead of DND, as that clearly is not enough to not get disturbed.

Friends who were in a yacht somewhere there was a major tsunami said they didn't notice it.

Let's say the swell is 2m high: in deep areas not near the coast the yacht moves slowly up and down with the swell - it isn't a "wave" (well it is, but it's slow).

The reason the shore is dangerous is that the tide coming up two metres (the wave) can turn the shoreline into a wide river of water. It isn't a wave like you see in the apocalyptic movies. Sometimes the geometry of the shore amplifies the wave to a much deeper height.

But yeah, don't be near the shore in your boat for a tsunami ;)
