Japan on our minds

There is some anxiety in our house at the moment about the inability to contact some relatives in the earthquake affected areas of northern Honshu. One in particular works in one of the tsunami affected towns, quite close to the waterfront.

In the meantime, the best commentary on the Japanese character and its response to natural disasters I have read is by Nicholas Kristoff in the New York Times. It is well worth a read.

Update: an email came through this afternoon that the people we were most worried about are OK, but there’s still a couple of others about whom we have not yet heard. They would not have been close to the water, however, so we trust they are OK.

Update 2: of course there are heaps of videos being put up on Youtube, but I haven't yet spotted the remarkable seaside town destruction footage that I was watching on TV earlier tonight. But Boing Boing had this video up, showing some very unnatural looking behaviour by some Tokyo buildings:

Actually, I see that a couple of million people have watched this version of the video on Youtube (because it has the link from Boing Boing), but only 5,000 or so have watched the original, uncropped version which the guy also has up on his Youtube account. I actually find the original more interesting, as you get to see other people on the street watching the sway:



Update 3:

I don't want to turn this into disaster porn, but the video below is similar to th longer one I mentioned above that I saw on TV earlier tonight. It does get a bit upsetting when it turns briefly to the scared child and shocked adults watching from their safe point:



Update 4: Let's hope he's wrong, but a UK geophysicist is quoted at the Nature web site saying this:
"Although certainly very big, today's quake was not totally unexpected," says John McCloskey, a geophysicist at the University of Ulster in Coleraine, UK. "Technically, it was in fact an aftershock of the weaker quake earlier in the week — even though it may sound odd that an aftershock can be stronger than the main shock." ...

"The previous quake, although much smaller, significantly increased stress in the fraction of the fault zone that ruptured today," says McCloskey.

The sequence of quakes has probably also affected the stress field further south along the fault zone, critically increasing the earthquake risk in the Tokyo region, he says.

"There is a strong interaction of quakes along a subduction zone, and we can certainly expect a number of major aftershocks in the next weeks," he says. "Some may be as large as, or even stronger than, the quake that last month devastated Christchurch in New Zealand. And chances are that another very large shock could occur to the south near Tokyo."

My apologies for worrying reader Geoff, who's due to fly into Tokyo soon.
