We need a head count!

A 7.0-magnitude earthquake has struck off New Zealand's South Island, the US Geological Survey has said.

The epicentre was 55km (35 miles) north-west of Christchurch, at a depth of 12 km (7.5 miles), it added. Police reported widespread minor damage and local power cuts. Christchurch is New Zealand's second largest city with a population of about 386,000, but no casualties have yet been reported.

The moment magnitude scale, the only scale they use to measure earthquake magnitude.

Was replaced in the 1970s by the MMS, the media often miss attributes it as the Richter scale but the US Geological Survey which this number was taken from uses the MMS as, I think, everyone else does as well.

I live in Christchurch, in the western part of the city - about 5km from the city centre, and 25km from the epicentre of the quake.

It was one hell of a shock at 4:35am. It's now about 12:15, and there have been a bunch of big aftershocks, one or two near the 5 mark, and a dozen or so in the 4's, plus smaller shocks every 5 or 10 minutes for the first few hours.

The intensity was initially put at 7.4 by our GNS scientists, it's been revised to 7.1 (not just 7).

The damage you see is just from old buildings, everywhere in NZ is meant to be EQ-strengthened, but most old buildings haven't been retrofitted yet. Power is out to most of the city, as is water, and sewerage. Except for my area, which has all three :D It's kinda funny, reading about all this damage, and getting messages from friends, and not actually having any of the problems they have.

But compare: Magnitude: Port au Prince -7 Christchurch – 7.1

Distance from epicentre: Port au Prince – 25km Christchurch – 33km

Death toll: Port au Prince – 230,000 Christchurch – 0

I just heard about this.

Haiti wasn't really rich enough to make their buildings earthquake-resistant, so they were pretty much screwed from the get go. They probably had a higher population density than New Zealand as well.

Aye, I saw your FB page. You got a free extra holiday without having to worry about getting your appartment fixed. :) But for those in other areas it got to be rather unpleasant to say the least.

Atleast nobody got killed. :)

Yeah, the water quality dropped yesterday, and we've still been getting aftershocks in the 5-4 range (about 15 last night, and maybe 10 today).

The biggest problem is the water supply, sounds like a lot of the pipes are damaged, and the eastern parts of the city still have flooding problems, though all we have to do is boil our water.. My suburb is largely unaffected by all this - I only spotted a couple of cracked brick chimneys as I walked around this morning.

Looks like the damage will cost about NZ$2 billion, but here we have government insurance for earthquakes, and they've got about $8 billion in cash, so no problems.

It also seems like it was a minor fault line. We're still expecting an 8-9 magnitude earthquake sometime from the major fault, and I guess this has given the city a good test run.

Just part of living on the Ring of Fire.
