But I can't see how this is possible:

”In the most dangerous quakes, even phones turned off will make a noise and alert users'

Good idea though.

"In the most dangerous quakes, even phones turned off will make a noise and alert users"

What ? - When the phone falls off the table ? How can a phone which is OFF have any functionality at all ?

I think a Stuff journalist has seem this article and paraphrased it without doing sufficient spiel checking.

I'm surprised they didn't morph it with this article as well:

Yeah that other article was interesting also.

I've emailed the article writer to query that.

So you have to have an earthquake to get the alert but surely you would already know about it from the shaking. So what's the point?

Now if the phone could, unlike Geonet, predict an earthquake before it happens then that would be something to write about.

The quake could be a bit of distance away from you but close enough to potentially cause danger. The phone alert will arrive at least a few seconds before the quake waves which travel through the Earth much slower than the speed of light. Thus it could give you time to drop, and cover.

Interesting. Stuff seem to have deleted the line "In the most dangerous quakes, even phones turned off will make a noise and alert users"…............

Perhaps my email to them suggesting that isn't possible might have stuck a chord?

Not to mention the ramifications for privacy and security if the phone was indeed quietly operational when it appeared to be off.......

That would be very serious.

Ahhhh so that answers why I couldn't for the life of me find that quote.

They left it there for a couple of hours and then removed it

Really it shows a lack of understanding of tech and the lack of logic. Electrical devices which are turned off simply do not work.

If phones could receive alerts even when turned off - then they're not really off at all. And that would be a very major thing indeed. With REALLY HUGE privacy and secutity ramifications !!!

Battery life would be compromised too.

That too. I think it was a case of a Reporter who didn't quite do 'due dilligence' on her story lol. The bottom line is simple. If it's OFF then it's incapable of doing anything.

Maybe it makes a noise when it falls off the desk during the shaking?

The graphic in the Stuff article illustrates a magnitude 6.1 earthquake in the Jakarta area. Wikipedia reckons P waves travel at 5 - 8 Km/s and S waves at 1 - 8 Km/s.

So by my calculation the example suggests the network has to deliver the message from someones phone to the network, have it processed somewhere by google's servers, back into the network, to the tower nearest you, to your phone, where it beeps, you unlock and read the message, and then stop drop and roll - the P waves arrive in 2 - 3 seconds, the S waves in 2 - 16 seconds.

Give it a test out of the blue with your partner, see if they are fast enough.

errrmmmm ?

Jakarta is about 7,712 km from Nz.

These waves you refer to - it's quite impossible they could travel through the earth at 1% of the speed of light. You're talking 3500Km per second ? Not possible. Think you need to recalculate that one.

That's what I thought, I figured the reporter was taking the pixx. In other words, the house would be shaking so much (during the quake) that the phone would be vibrating, well of course it would, along with everything else in the house!! But sadly, there was no tongue-in-cheek. But it's not the first time I've heard that even powered-off phones can still be activated by this particular emergency alert, and the only way to circumvent it, is to fully discharge or remove the battery. I've just got a new Galaxy S21 Ultra from work and no way can that battery be easily removed so perhaps this is the way things are heading. Perhaps even fully discharged maybe there's 'just enough' in reserve to keep the foil-hatters awake at night !!

How the hell can a powered off phone receive any kind of alert ?
It's impossible.
A cellphone thats OFF can't do anything whatsoever except be a paperweight. Completely ridiculous. Of COURSE off means OFF. If it didnt' then that would be a HUGE security and privacy issue.

Anyway I challenge you to try making toast with your toaster turned off.
Or doing any function of any electrical powered item - when the power is turned off.

Completely impossible. Hows the phone going to receive a celltower signal when it's OFF ? It can't - that would mean it's NOT off and it's actively pinging the celltowers otherwise theres NO way it could receive a signal.

And that would mean the every single security researcher in the world has missed this HUGE bit of info - you know, the one that seems to say that a phone which is depowered can still receive communications, (and it'd have to be capable of sending signals also in order to do so). That's about along the same level of believability as UFO's using MacDonalds drive thrus.

Although some phones will turn on if you have the alarm set. True story.

Yes I've just read that. But that would be a very low level function far removed from 'connectivity' as such. And few phones would do that I'd guess.

It's all part of the plan to drive the public into a state of paranoia and thus immediate submission to the State Directives that are starting to pour out of Welly. "Do what they say or you will die" is the chant.

And no, I don't have the foil on tonight.
