Thread: Earthquake !!

And breaking news - another earthquake in Victoria, Murrayville near the SA border 0347. Not as severe, first estimate 4.8 magnitude and several aftershocks.

That would arguably be the most remote part of Victoria - and no-one's likely to be on the Border Track at the moment either.

Of course, another factor is how closely buildings adhere to their design when actually being built. But that article points out that the older building code was inadequate. It also points out the major effect of the properties of the subsoil on ground movement in an earthquake (the Christchurch quake showed this up dramatically).

Some clients of mine in Tokyo had part of a subway station under their 20 storey building - their engineers told them that in a really big earthquake their building would stay upright but would punch down into the subway station in one piece and they'd be exiting to street level from the second or third floor.

The Fukushima earthquake was about 400 km north of Tokyo Disneyland but it still destroyed their carparks and it took them months to reopen. Tokyo Disneyland built on reclaimed land that used to part of Tokyo Bay and is close to a major fault line that runs across Tokyo Bay, so it is in fact a sketchy place to have an amusement park.

When I lived in Tokyo I had serious gear to prepare for a bad earthquake - as part of my job I got to read the reports on what was expected to happen if a big one hit Tokyo, and the reports on what had happened at Kobe - but most people I spoke to (both Japanese and expats) thought that I was a lunatic: that wasn't the case after Fukushima, in fact a lot of expats left permanently. In the end, one of the reasons we left Japan was my concern about being in Tokyo if a big earthquake hit, in particular that my kids were scattered around the city at different schools and we might not be able to get everyone to safety. My wife thought that I was worrying too much, but when we were watching the tsunami and what was happening in Tokyo and when Fukushima radiation cloud looked like it was about to drift across Tokyo (which would've particularly affected kids) she actually said that she was grateful that I'd been so worried.

There's a lot to be said for situational awareness.

Now why would you quote an overseas website rather than the Australian one? Earthquakes@GA (click on the big red -> orange -> yellow blob on the SA border.

Never felt a thing. but the the Earth normally moves for me as a matter of course anyway.

Woke me up at 3:19am. Windows were rattling, and the bed was rocking……. And not in the good way.
