Speaker: Shenzen's hire-bike explosion, in reply to Paul Campbell,
Perhaps the cable car could be retrofitted with bike racks

Amazing. All power to you and SO and your bus. Have you got any means of communication other than cellphones?

Rosemary, if Significant Other is in bed when earthquake starts, he'd be best just to stay there and cover his head.
If he's up and about and in wheelchair, he's probably best to put the brake on so he doesn't move around too much and just stay put and cover his head as best he can. Have you got your tall furniture well secured?
The lovely Beck Eleven describes how running around during the Feb 2011 quake got her a nasty injury: If you can keep calm during a quake, that's good. I ran during the February one and the buckling flipped me headfirst into a wall. That was my neck stuffed for almost a year. -
Hard News: #eqnz: Okay?, in reply to Prudence,
It’s the lintel (150 to 200mm deep) spanning the distance above the door that offers protection. Some houses have door openings that are full height, (the height of the wall) in which case it will be the truss above the opening that provides support. A doorway is a good place to be in an earthquake.
Actually, Prudence, the doorway advice is outdated. This is the latest from MCDEM:
Are you wondering why we recommend "Drop, Cover and Hold" rather than getting under a doorway during an earthquake? The important thing is to lower you centre of gravity so you don't fall over (drop), make yourself a small target and protect your organs, head and neck (cover and hold). Doorways in modern houses are no stronger than other parts of the house and doors can swing and injure you. You can find out more here http://getthru.govt.nz/disasters/earthquake. Please share. -
Hard News: #eqnz: Okay?, in reply to Ian Dalziel,
This is not to say every Super Moon or Full Moon (or close approach to the sun as well) will cause an earthquake, but they might always raise the odds and test a delicate system for confluences of geological events and other ‘chinks in the armour’…
Mark Quigley and Brendan Duffy express it well:
Small amplitude and large wavelength tidal deformations of the Earth due to motions of the sun and moon influence stresses in Earth’s lithosphere.
It is possible that, for active faults that are imminently close to brittle failure, small tidal force perturbations could be enough to advance rupture relative to the earthquake cycle, or to allow a propagating rupture to travel further than it might otherwise have done.
But the specific time, magnitude and location of this or any other large earthquake has not been successfully predicted in the short-term using tidal stresses or any other possible precursory phenomenon.
Deliberately vague predictions that provide no specific information about the precise location and magnitude of a future earthquake are not predictions at all. Rather, these are hedged bets that get media air time due to the romantic misinterpretation that they were valid predictions.
Most earthquake scientists, including those that research tidal triggering of earthquakes, highlight the importance of preparedness over attempts at prediction when it comes to public safety.

Hard News: #eqnz: Okay?, in reply to TracyMac,
Regarding huddling in door frames, if your house is fairly modern, there's no point - there are no extra wall studs around them these days.
Civil Defence recommend crouching and covering near an interior wall away from windows, appliances, etc, if you can't get under a desk or table.
Or simply stay in bed.

And this was the NZ Herald as of yesterday: But according to online lecturer in politics and PhD candidate at Swinburne University, Bryan Cranston, polling aside, it is actually mathematically impossible for Trump to win the US election.

Envirologue: 1080, "eco-terrorism" and agendas, in reply to Rosemary McDonald,
Back in 2010 I tried to find out on what basis the Food Safety Authority approved for use a certain agrichemical
Instead of hinting darkly, why not just state what it is, post a few links to the relevant documentation, and then it might be possible to have an informed discussion about it. Note that anyone can apply for a reassessment or review of a hazardous substance if you believe there are valid grounds for this.

Envirologue: 1080, "eco-terrorism" and agendas, in reply to izogi,
It’s not necessary to be a qualified scientist to actually do useful science, and verifiable measurement is something that’s sorely needed in support of most anti-1080 claims I’ve seen.
Nicely said, Izogi.

Envirologue: 1080, "eco-terrorism" and agendas, in reply to Rosemary McDonald,
I did read this , which of course was ‘discredited’ by the establishment.
'This' refers to a critique of the PCE's report by Jo Pollard. Sure it was discredited. This was because it's mostly scientifically illiterate. For instance, Pollard claims that Because 1080 poison is highly soluble it spreads very fast in water and also up food chains.
Sorry, but that's just weird. 'Dilution' is a more useful concept than 'spreading very fast in water', and highly water soluble, non-persistent compounds do not biomagnify up food chains. She's just making stuff up.
