It really is horrifying to have such a long life cycle .....
Unfortunately the forum system here does not pass on Subject changes to all the previous messages posted but if you care to change the Subject from Scotland .... next time you post -- that way it's up to you <s> -- it will be inherited by those whose posts later are replies .....

Christchurch's Port Hills are nearly half a metre taller in places as a result of the colossal forces unleashed by last week's earthquake. Lyttelton was now several centimetres closer to Christchurch.
The fault (Fault B in a post earlier above with pics) was angled so that most of it lay beneath the Port Hills.
The faults associated with the September 4 and February 22 quakes were separated by what may be at least two more hidden faults underneath Christchurch.
Aftershock patterns suggested at least two north-east-south-west trending faults lay between the east-west Greendale Fault exposed at the surface in September last year and the fault under the Port Hills.
One of these looks like Fault A, patten seen in the pics in a post earlier in which I red arrowed out to Parklands / North New Brighton.
I had noticed the line on a Radar image quite some weeks ago from a Japanese agency and I dotted whie lined suspected fault paths myself. I placed the dotted white lines into the Radar image on the 4th of Jan and saved it.
The other not sure yet Quads is studying hard the data, It could be the line that goes North to the East of the Airport and then North East to the river north of the city.
The amount of data to look at and analyse is big, let alone when an error occurs

It makes to real and closer to be getting the details from you Quads ..... Glad you are able to do it.
Are you on laptop (if so how do you recharge) or have they restored power for you?

I am in one of the areas that got power back in half a day, but the water is still at times on and off with stuff all water pressure really.
You are not allowed to drink it without treatment, No hot water either.
Got one of the aftershocks last night at 4.6m only 5km deep. rattle rattle.

You seem to be well versed in seismology. Any formal studies in the earth sciences? I took quite a few courses in college and have always been interested in geology as a hobby. I am finding your reports quite interesting. Your quake seems very similar to the Northridge quake here in 1994. While everyone was worried about the "Big One" happening on the San Andreas fault, a buried, previously unknown, thrust fault caused a lot of damage with a 6.7 magnitude quake. It got everyone thinking very seriously about blind thrust faults, one of which lies under metropolitan Los Angeles. Oh, the joys of living on a plate boundary!

Studied Earth sciences in with the other sciences at school until the end of school, seeing as NZ is an earthquake country it was complusory to study earthquakes, plate tectonics etc. (mind you there are kids who decide to have it go in one ear and out the other).
After school I went more into electrics, electronics, Computers and Basic Astrophysics (that pushes the brain).
I am a nerd as someone put it It's not that hard to use the physics branch etc., Just don't ask me to cook, it comes out black.
Here is the NZ map showing the MMI scale of 8 and how a lot of the instruments detected in NZ. (thanks to GNS)
The 6.3 shake was also detected in London (UK) on instruments

What is so fascinating about New Zealand is that the ocean floor subducts under the north island on the right hand side of Quads' image, but the south island is climbing over top of the Australian plate on the opposite side. Add to that a general slide to the south by half of the south island. It keeps me awake nights trying to imagine the movement of the plates.

I'm wondering if Quads will open his house to all of us if we'd like to take a Lord of the Rings tour of New Zealand. Except now may not be the best time for a friendly visit.

Yeah Liquification ring and dust from that for miles on end.
Here are the drums below for Canterbury, North to South, the meters are spaced far enough apart over the region, for the ones selected.
There are a LOT more meters around Canterbury, and more has been added over the last week as part of the CanNet network, this is only 6 drums.
The drums should update every 10 mins or so by refreshing. (F5 key)
Thanks to GNS
