things that go 'bump', and all falls down

[Phreddy]

yep!

another one strikes Christchurch and basically demolishes the city centre,
and sadly this time there are a lot of deaths

lots of photos and videos here:

Jeeze, that's bad. and to think we moan over here about a bit of rain and snow once a year...

[Phreddy]

in the light of the day after it is looking more and more of a horror story.................

on the plus side, it has shown that people still care about their
'neighbour', and get in and help any way they can

the support from all over (the world) is incredible.


God knows what the final impact will be - current estimate cost wise
is running at $6 billion (£3 bill), and thats on top of the September one
that is looking like $3.8 billion (with a lot of that recovery being trashed
this time round)

I have family (cousin) near Christchurch and thankfully all is OK with her. Some structural damage but no injuries !

I too have family in Christchurch, took 5 hours to find out if they were ok and luckily they survived, not so sure about emotional damage though.

Hope the rescuers continue the amazing work, and that many more can be plucked from the devastation.

Kiwi's are a tough lot and will pull through! Get the All Blacks on the job!

Truly, it's a tragic event, just as any hi-energy earthquake is.

Strength and resilience to you all---the sun will shine on NZ again!

Glad to hear all your people are OK. The office block that went down flat as a pancake gave me the shudders.

eeeek

[Phreddy]

Watched a tv program on Sunday night that was interviewing some of the earthquake type boffins, and the figures they had were incredible -

- the horizontal acceleration of the quake measured at just over 1G, or "9.81 m/s squared" which is one of the highest measured in the world ever.

- if the city was sitting on bedrock rather than on alluvial flats, it would have been totally flattened. the liquifaction had taken a lot of the edge/energy off the quake.

- due to the liquifaction, some of the residential areas may be abandoned as they have sunk to an extent that they are a permanent flood risk now,
and rebuilding there would not be allowed.

- well over 10,000 houses may need to be demollished


a note on the horizontal forces
if applied in one direction, all the buildings would be travelling at a speed
of 35.3 Kph (22Mph) after just one second

[Graeme]

These numbers are good news, they show that the pressure is being released in small movements.
If they stop for more than a week then start to prepare for another major shift when movement resumes.
Through time they should decrease in magnitude.

My thoughts are with people in Japan just now..........................







makes Christchurch look like 'nothing' in comparison

[euphoriabuzz]

OMG , I am amazed at the pictures of the tsunami on BBC news, and now they have a radiation leak too, I hope the rest of the reactor stays sound. What a devastating event for all. lets hope we provide some assistance to the people who are stranded in the wake of the water. I wonder if anyone running Quake Catcher got useful data on their machines.

Some more info from the Christchurch quake
(from tvnz.co.nz)


An unusual combination of at least four seismic effects caused last month's deadly magnitude 6.3 earthquake in Christchurch, scientists have found.

GNS Science said the intense shaking in Christchurch was caused by the high amount of energy released in the rupture of the fault, the direction that energy was released -towards the city, a recently discovered trampoline-like interaction between geological layers under the city, and the close proximity of the earthquake to the city.

The ground accelerations in Christchurch, the largest ever recorded for a New Zealand earthquake, were as much as four times higher than the highest accelerations measured in last Friday's magnitude 9.0 earthquake off the east coast of Japan, GNS Science says.

The largest ground accelerations in Christchurch during the February 22 quake were more than twice the acceleration due to gravity.

Seismologists have calculated that the energy released in Christchurch was equivalent to a magnitude 6.7 earthquake.

GNS Science Seismologist, Bill Fry, said it was the acceleration that caused the 'jolting' feeling people experienced during an earthquake.

"A Formula 1 racing car accelerates on average at less than twice the force due to gravity, and during the magnitude 9.0 'mega-quake' off Japan's east coast last Friday, peak ground acceleration was recorded at only about 0.53 the strength of gravity, or less than one quarter that recorded in Christchurch," Fry said.

The faults that failed in both the September magnitude 7.1 and February magnitude 6.3 Christchurch quakes were very strong, with high amounts of friction holding the two sides together, Fry said.

"When a 'strong' fault breaks, it releases more energy than an equal-sized 'weak' fault would. Think about the difference between breaking a 1cm-thick sheet of styrofoam and a 1cm-thick sheet of plywood, and the amount of jarring you would feel in your hands.

"The Canterbury crust is analogous to the plywood, but most earthquakes are more like breaking the styrofoam."

In addition, seismologists have discovered that the earthquake rupture was faster than most earthquakes of this magnitude.

"In fact, the rupture travelled at about the same speed as some of the waves that were generated by it," Fry said.

This implies that as the waves from the first second or so of the rupture were travelling toward Christchurch, new energy was being released during the next couple of seconds, and these were added together to make the shaking particularly 'punchy'.

This resulted in something compared to the supersonic boom of a jet aircraft, he said.
