Hi Eric, I wasn't offended. You were quite correct in your generalisation, and I have seen it first hand regarding funding. I'm just glad that I like old dead things and mud and followed what interested me rather than the money. I have so many mates working in mines in both australia (sic) and New Zealand, as well as in mineral exploration. While I like getting out and about, money has never been the motivator for me and consequently I have lived on the bones of my arse for years until I became a Laboratory technician in a tertiary institution.

It's true though, the funding and the large-scale recruiting comes from the big mining and exploration companies such as Rio Tinto, Pells Sullivan Meynink, Oceania Gold, et cetera, while the rest of us have to make do with the crumbs.

I keep my ears open, but nobody seems to be talking.
However, over the weekend I spoke to a geophysicist friend of mine who has done some RADAR surveys around the red zones in Christchurch and his (unofficial) opinion is that the return interval of the major Christchurch earthquakes is a lot less than 16 000 years. He thinks it is reasonably 'common', but when pressed he wouldn't say. This is from someone who is a friend, so imagine people who don't have contacts trying to get information. It's like blood from a stone.

I may well investigate the presence of marine microfossils (foraminifera especially) in liquefaction material to try to obtain some dates, mostly of penultimate disturbance, I guess; and keep 'pressing' my mate to look for palaeo liquefaction tubes in the profiles (which he admitted he hadn't looked for; only the present day ones) and see if there is some sort of confinement we can come up with.

As a lowly technician, and in a field that is not as well patronised as the 'sexy big money' fields, I try to glean what I can from the Big Guys upstairs!

Also, Puterman (and Muzzy) you guys rock. Thanks so much for all your work. It is appreciated. Same with all you other contributors who I have left out. This is one of my favourite threads on this site.

Eric: Kia kaha, fella.

Okay, so I still say we're in the lull. There's been that 5.8M. And then there were some 4's. So, I was hoping things would resume as usual and there would be nothing to observe except the seemingly randomness of it all. But there is something that I'm noticing in today's quake list. The 4Ms are coming in couplets. Two at time within an hour or so. Pop pop. Like the popcorn maker. I don't really think it means anything but it's something to notice.

Good for some doom perhaps? Still awaiting Spacejockey1's mag 7. I assume he was talking UTC so 21.5 hours to go then.

I notice that too. Small swarms on the ridges especially.

Can't say I'm surprised that I'm to awake to no 5s again.

Yes, UTC...Counting down the hours! lol

Would be typical if the God's (moon & planets) would let me down on this one though.

Looks like there was a 3.5 on the 9th, in the spot of the 7.2 M 1929 Grand Banks EQ.


2012/04/09 - 00:12:00
44.63N 55.67W
Depth: 18.0*
Mag: 3.5 ML Felt: No
275 km S from Grand Banks, Newfoundland

1929 Grand Banks Earthquake:

Local Date and Time: November 18, 1929 at 5:02 pm Newfoundland time
UT Date and Time: 1929-11-18 20:32 UT
Magnitude: MW 7.2; MS 7.2; mB 7.1
Maximum Intensity: (Rossi Forel) VI
44.69° N 6.00° W
Depth: 20.0*


Ok, it appears they do occur, just not that often.


The earthquake triggered a large submarine slump (an estimated volume of 200 cubic kilometres of material was moved on the Laurentian slope) which ruptured 12 transatlantic cables in multiple places (locations of cable breaks can be seen as small red triangles on the isoseismal map) and generated a tsunami (a large induced sea wave). The tsunami was recorded along the eastern seaboard as far south as South Carolina and across the Atlantic Ocean in Portugal.

This site has lots of sources and photos of the event. I just hope all these years isn't leading up to another. I find it interesting how quakes in the Atlantic and up north come to occur.

Well it's one of those times you really wish you weren't right about something like this


Though I predicted a 7+ for the time period, I certainly didn't conceive that an 8+ was in the offing!

Let's hope that there's no big tsunami with that one...

how is it two huge earthquakes happen in sumatra within 10 years and nothing on the west coast?
big pressure buildup?

Seems like a big aftershock just rolled through. I am sure this is normal, but jeesh two >8 back to back would be enough to make me a little anxious. Prayers for the people in the area.

Yes, a major aftershock (assuming that it's close enough and within the same fault system as it seems to be) -- and really a bit bigger than we'd typically expect.

Makes me wonder if the primary quake might get revised back upwards.

I know you've posted some data, but here's the USGS data page as well that includes coordinates etc:

Thanks Mike for posting the extra info. I can't imagine what this must feel like to them. Do you know if the tsunami ever came to anything. I am looking for the pager alerts and am sad to say that USGS.gov is not my friend when it comes to finding info. I really need to make myself more familiar with that site.
