I thought USGS reported quakes over 5.0 in NZ - the North Island 5.6 isn't showing up

I don't know what's up with the USGS not showing the NZ quake. I will write them later if I have time - it's going to be a busy day. I'll check the links posted when I get onto high speed a little later

First I apologise for quoting all of this but since it was in an email to me it is the only way of showing it. This was with regard to the 5.1 they did not show.

We locate and report on all earthquakes world wide of magnitude 5.0 and larger in one hour or less if possible. We do not locate earthquakes smaller than 4.0 outside the US unless they have caused significant damage. Earthquakes
this small very rarely cause any damage at all.

Earthquakes smaller than 5.0 down to magnitude 4.0 are located as we have time and if we have enough data to locate them, regardless of where in the world they occur. Earthquakes occurring outside the US and smaller than about magnitude 4.5 are difficult for the USGS to locate if there is not enough data. Most of the time there is not. Most of the aftershocks still
occurring from the large New Zealand earthquake are in the low 4.0+ magnitude range and therefore difficult for us to locate without data.

The magnitudes posted by the New Zealand web sites may be higher than ours due to different sets and amounts of data. Even though the New Zealand website locates an earthquake and reports a magnitude larger than 4.5 does not mean we have enough data to locate it or compute the same magnitude. Nor does it mean that our data will indicate it is larger than 5.0. The scientists in New Zealand have access to 100s of more earthquakes stations there than we have access to and are therefore able to locate many more of the smaller earthquakes than we are able to. For aftershocks smaller than about 4.5
we must wait for data to be sent to us from New Zealand. Data is not sent to us in real time or even on a daily basis.

If we don't have the event located, then we did not get/see the felt reports. Anything under mag 5.0 and above 4.0 we locate only if we are able and if we have enough data to locate it. If our systems do not locate it automatically, then we won't know it happened until we get local data.

One of the analysts did check and this earthquake is in our system. It looks like the WEL data for it has come in but we did not locate it ourselves. The IDC location puts it at about 4.6 which is still probably a little high. Because of this magnitude and the fact we didn't locate it in the first place, it most likely won't get located until it is in review for the PDE.

Um bovine something or other?

There are the recorders in the IRIS networks that are in NZ.

Here it is on HIZ HIZ.NZ.10.HHZ.2010.267

And here for WPVZ WPVZ.NZ.10.HHZ.2010.267

3.519 ML 14:55:59 UTC Loch Ness New Zealand.

Eh? Loch Ness is Bonny Scotland. Had me going there for a minute!

Yeah its pretty slack none of the networks reported on the Tokoroa quake, the depth of 197km might have something to do with it, but the USGS have reported quakes at that depth in the Bay of Plenty before.
5.6ML should easily come in over 4.5Mw if not 5.0mb

The Americans just never been the same towards NZ since we said they can't bring their Nuclear ships into our territorial waters

The reported as Felt lists are all messed up, there was a 4.3 in Canterbury 3 minutes later, so a lot of the Tokoroa Felt locations are from that

Didn't feel it BTW, so windy here the house is shaking 24/7 anyway

Thisisit is at the end of a road in the mountains, I guess the surveyor had enough and turned around there

I Hope the rumbling stops here - I wonder what the condition of the Dam is

I don't buy their excuses.
I siphoned out the Christchurch felt reports from the Tokoroa list and that left 432 reports, mostly in the Hawkes Bay, which is about right given the location of the epicentre
I always assume that you can at least multiply the number by 10, as a lot of people don't bother filling in the reports and others don't even have the internet.
Possibly by 20-40 if you assume each person filling in a report is part of a family group who all felt it but just filled in one report ( or didn't fill in any reports)
So 432 - 4320 - 8640 to 17,280 people possibly felt this quake

and USGS doesn't feel that it is significant enough to post it on their list.

Yet they post a 4.5 near Fiji (the day before) that was 484km deep and reported felt by ONE person in Suva as "weak"

USGS = unreliable

I honestly believe there are some who look at the drum and think "Oh, I must have felt THAT one"... I had several friends from Hamilton, Hawkes Bay and Whakatane saying they felt nothing at all.

And yes, I think the Cantabs got a wee bit confused when doing their Felt Reports! Although I had some arguing that they definitely felt the North Island one... hmm.. I think not!!

Nice little 4.3 to wake us up this morning..

reply to post by muzzy


No I don't buy them either. 100s more stations? Where did they dream that one up? On that map of the recorders there are 11 stations. I don't think there are many more than that. I need to research that and then take USGS to task about that statement. I will not be fobbed off by a bunch of bureaucrats.

This is the last 7 days 3.5+ Mag for NZ from QVS Data (I will sort the very accurate place names!)

Bit bumpy down there! There seem to be a few IN Canterbury (Hotel Off The Square, Opawa, Bromley etc). I thought the epicentre of the big one was about 33km out?

You're correct - the quakes tonight were IN the city of Christchurch as opposed to their more usual locations in rural Canterbury ie. southwest at Rolleston or further west out near Darfield and Hororata.

Another interesting observation. People in Rolleston area, who have been right in the thick of the aftershocks and feel pretty much 99.9% of them, didn't feel this big ones in Chch, yet Chch feels most of the ones that Rolleston gets, to a lesser degree. In addition, people in the towns to the north of Chch (Rangiora/Kaiapoi) felt the ones tonight in Chch city a lot more than others - they rarely feel the Rolleston shocks.

Could this mean that tonight's activity was on a different fault line?

Yes, Alaska has been acting strange as I have been saying for the past 2 weeks.

Then we have the following 10 minutes or so later above. - this one being south of where we usually see quakes in that area. I am thinking we may see something in WY today.

Feeling a little unsettled with the Alaskan quake earlier. The area that shook is near where some of the largest quakes to hit Alaska have hit. It has now been many hours and there have been no aftershocks to speak of - - .

I know, what's up with that? I pulled up the list and had to do a double take with the name.

that's a moderately seismic area, but I was surprised to see it on the list too

2nd line

reply to post by MoorfNZ


Yeah looks like a totally different Fault, or maybe its like a fracture off to the side.
I reckon theres a fault along the foot of the Port Hills as well, judging by where the aftershocks have been for the last 3 weeks. Or the Ferndale Fault runs into the Lyttleton volcano and bounces back to the north becasue of the change of rock there

Heres a map of all

1040

aftershocks so far, sorry its only available as Google earth KMZ file, as there are too many icons (epicentres) for Google Maps to cope with
The file is divided into magnitudes which are listed by date/time.
You can click or unclick each sub file to see each magnitude locations.
Hover mouse over icon to get quake size, click on it to get detail on popup balloon

I just threw this together because they have started listing the extra smaller 2's missed before and the numbers are building up
Day1 - 9 extra quakes
Day2 - 7 extra
Day3 - 106 extra
Day4 - 64 extra
Day5 - 68 more
and so on
