I was on a city street doing ~30mph.

What beautiful country. That road would have been absolutely terrifying to try to drive in the dark after the quake, and indeed shows why it would be safer to stop and get out. There's really no way to know where to be safe, is there, worse than a hurricane or even a tornado which usually have more or less a pattern.
I kept wondering how he got past some of those breaks, like that one place it looked as though the road completely blocked by rubble and another where it had sheared and the far side looked about 1/2 a metre or more higher than the near side. Thanks for posting that, it was interesting to see just how widespread the damage was, it's not really concentrated in a small area at all. So lucky you escaped that.

Kind of puts the whole "we're in charge; it's all for us" paradigm in perspective, n'est-ce pas?

And to think that that is just on one side leading up to the worse effected part of the road, see link.
Now to all truck freight has to take a longer alpine journey of about an extra two hours which in turn will push up retail prices.

That's an awesome amount of earth-movement.

Indeed. I'm also struck by how insubstantial the soil/substrate was in other areas, seeing the washes and slides. Further, in view of these conditions, I'm amazed at the roads having been built in such vulnerable ways, though I suppose it made sense at the time. There is an area in Cali, Big Sur, where the road is exposed to such danger; it is regularly damaged/blocked by slides, even without temblors. One wonders; what would it cost, given modern methods, to re-route it, compared to the cost of continued frequent repair. I think the problem with the Big Sur highway is that the "safer" area is highly mountainous wilderness; is that perhaps the problem in NZ?
I would note that Cali, despite being the most populous state of the USA, has large areas that are thinly-populated and wilderness, a great resource for recreation, hunting, and solitude. I'm so pleased that my farm is out in some of that thinly-populated part, next to wilderness, hence the variety of critters that come around, though they can be a PITA, on occasion.

Only very small areas of NZ's South Island have what you would call old granite or volcanic type rock, everything else is mostly 2nd or 3 third sedimentary, so its rather soft and prone slides. steev can ya post a link that shows Cali, Big Sur,i;m interested to see it. They are looking at the option of re-routing that coastal state highway, but there's not a lot of alternative routes to chose from. Myself i can see engineers recommending using the advanced tunneling technology that available today, this and along with now having receded water line thanks to uplift a new road could be built further out from the cliffs, after all they've now got plenty of rock material to work with. Couple of interesting photos doing the rounds   |

www.bigsurcalifornia.orgThat is quite a similar coast line the "safer" area is highly mountainous wilderness; is that perhaps the problem in NZ? One of the other problems with going inland is dealing with higher areas prone to snow |

I live at the upper reaches of the New Madrid fault. History books describe great two great earthquakes in late 1811 and early 1812. I'v read they are estimated to be high 8 or even 9, made the Mississippi river run backwards, rang church bells on the east coast. An earlier one is supposed to have caused the great falls of the Ohio about sixty miles from here. Over 200 years now and nothing but a little rattle now and then.
You folks being a little more used to it are somewhat prepared with reinforced buildings and the like. When that thing cracks again we're screwed.

I wonder when it last went off big-time before 1811/1812.
I think they're predicting the next Big One from the San Andreas fault as 70% probability in the next 30 years. No matter; we'll prolly be suffering so much from Global Climate Change that sudden death will be a relief. I think this prediction is why the Bay Area is building ever-taller buildings and seeking ever-denser population: so "God's Will" will reduce Cali's population most efficiently.

reed you are right, we are a well prepared with most modern building being reinforced while homes made from timber or a growing number steel framed. Also a growing number of historic building have or currently being earthquake strengthened.
