Date time 2010-09-26 18:28:01.3 UTC
Location 52.58 N ; 179.82 E

Expect revisions!!!

Actually looking at this there is nearly 4 deg difference in the longitude. Maybe it is not the same quake. Off to look at the webicorders.

I was expecting that! It is interesting to note that when USGS revised that magnitude the location jumped by several degrees of longitude and is now much closer to the EMSC value posted.

This happening SW of Iceland again.

4.8, 5.2 or 5.4 - these may be three events. Can't tell yet.

Maybe the 5.4 and the 4.8? Actually these look like three different quakes.

Difficult to say as not much is showing on BORG and that is all we have to go on.

We had a 6.4 near White Island today half an hour ago at 5.14pm. Was quite a deep one thank goodness, but not that great that it was out near White Island (live volcano), bit scarey (nothing like in Christchurch though) so am totally not complaining.

www.geonet.org.nz...

Poor old Christchurch and Darfield are still getting the aftershocks happening.

Felt that one here on the Kapiti Coast


Almost the same feeling as the Darfield 7.1. It was just a very weak rocking (under the couch this time). Like the 7.1 I looked around to see if it was the cat playing around with the furniture but she was sleeping on another chair.
We are 510km away

USGS have it at 5.3mb. Geofon 5.2mb on the main list but 5.3mb on the event page
The Geofon NZ station phase magnitude readings are interesting compared to the USGS (same place different machine) the further away the higher the reading

Whats really weird is the distances at which it was felt www.geonet.org.nz...

some of the Christchurch ones might be mistaken local aftershocks from Sept 4, but look at those others

I have heard from friends who felt it in Hamilton and Hawkes Bay... I would have expected many more to have felt it - but I guess it was quite deep.

So... need we worry about any connection to this quake and nearby White Island where NZ's only active marine volcano is located?

What makes you think these are different instruments? These are as far as I can see all reading the same instrument the differences being in interpretation of the raw data which will be dependent on the program used to calculate this.

Earthquake readings are a very precise science [not] I will have you know. You can even see differences in arrival time for each station despite that fact they are the same, or as you put it different instruments in the same location. Either way there should be no difference in arrival time. This is purely down to interpretation of the incoming data which IS I assure you all from the same source.

I think we need a new universal scale:

1 - eh? earthquake? where? This covers 0 Mb to 2 ML

2 - so there was an earthquake? This covers 1 Mb to 3 ML and all Md and the rest in between.

3 - Mm was that an earthquake or did the cat fart? This covers 2 mb USGS to 3 Mb everywhere else and up to 4 ML in all countries outside of the States

4 - felt that - 3Mb USGS, 3,5 Mb EMSC 4 ML to 4.5 ML rest of the world

5 - the earth moved for me! - 3.5 Mw USGS, 4.5 Mb EMSC,6 ML rest of the world

6 - WOW that woke me up - 4.5 Mb USGS 4.7 Mw USGS, 5.5 Mb EMSC 6.5 ML Rest of the world

7 - HMMOG that was a bigie - 5.5 GS USGS, 6.5 Mb or Mw EMSC, 7.5 ML rest of the world

8 - JC that was serious - 6.5 GS USGS, 7.5 Mb/Mw EMSC, 8.5 ML rest

9 - OMG The world just ended - USGS such a magnitude is not possible as GS (Guesswork scale) only goes to 7 and we don't want nasty 7 and 8 magnitudes in the figures - in fact we are not too happy with 6's either, EMSC 8.5, rest 9.5 ML

To sum up, earthquake will now be graded as

EH, SO, MM (Do not confuse this with Moment of magnitude), FELT, MOVED, WOW, MOG, JC, OMG

In the interests of universality no numerical value is ascribed to this scale and as always the data is inaccurate because the Republic of Kiribati which produces accurate earthquake values has several thousand more seismographs than the USGS, EMSC and GeoFon combines and the data is accessible to no one thus you will always find that the USGS, EMSC values are not the same and conveniently less in case the world figures show an increase.

The result of this is that the recent NZ earthquake is now categorised as a WOW.

@ Puterman...

.. but, much as I hate to disagree with the Bill Bryson of seismology.. I would like to point out that your 7 scale is way out.. HMMOG just doesn't cut it.. might I suggest at least an "OMFG" and a change of undies?

Well I don't know. I think if you are going to have an OMFG/CU level then that really should replace OMG which should be downgraded.

Perhaps the upper end of the scal should be:

7 - WTF that was a bigie - 5.5 GS USGS, 6.5 Mb or Mw EMSC, 7.5 ML rest of the world

8 - OMG that was serious - 6.5 GS USGS, 7.5 Mb/Mw EMSC, 8.5 ML rest

9 - OMFG(CU) The world just ended - USGS such a magnitude is not possible as GS (Guesswork scale) only goes to 7 and we don't want nasty 7 and 8 magnitudes in the figures - in fact we are not too happy with 6's either, EMSC 8.5, rest 9.5 ML

Of course the scientists and geologists could perhaps consider a 10

OMGGAFMWTFCU. This of course would be pretty close to an extinction event.
