They say cities begin to be evacuated.



Reports from Mexico are putting this earthquake at a 6.5 Magnitude lasting as long as 5 Minutes - Thousands have been evacuated from buildings and homes

As Puterman pointed out there is the usual magnitude type difference, but here is some more bits and pieces of info on that quake to add to the confusion.

On the magma search data base it comes up as 5.582ML

On Geonet Rapid its 4.7, after 13 automatic attempts and 2 manual reviews
geonet rapid

based on the Felt Reports and the distances from whence they came I'd say it was more than 4.7. There were 4 x 5MM reports, and 417 total.

On the other hand it hardly shows on LISS SNZO (7:00 line) like a Mag 5 would. However the location is on the Pacific Plate, wheras SNZO is on the Australian Plate and may explain that. Thats why SNZO always shows Fiji, Tonga and Vanuatu quakes as quite large traces, they are also on or border the Australian Plate.

As for location, I'd go with the Geonet one at Irene River, that is a hot spot and there are quakes there all the time. USGS are notoriously wrong with locating NZ quakes, they have it about 20km SE, nearer to Lake Te Anau.
Likewise siesme.nc have it way up near Milford Sound.

Graphs?
nearest IRIS station nearby is Otahua Downs, inland from Oamaru, Otago,but it doesnt look very big on that ODZ.NZ.10.HHE channel
compared to Geonets ODZ

some of the other nearby Geonet stations show quite a big trace too, similar to ODZ
Wether Hill Road, close to Ohai, in Southland

Wanaka, Otago


So for the time being I'd go with Geonets report of 5.6, it may be adjusted after review (in about 30 days) but waddausgsknow

There's your 188 day quake .

In the event that the 188 day earthquake does succeed (this would be about 25-40 hours too soon), I do hope that this isn't a foreshock to something bigger to come tomorrow, in the Japan sort of sequence.

188 days from when?

The last one which was nearly a seven was on the 14th March. I know my maths is not good but I don't make that 188 days.

Since 188 days


Date/Time UTC,Latitude,Longitude,Magnitude,Depth(Km),Location
2012-03-20 18:02:48, 16.662, -98.187, 7.6, 17.5, Oaxaca. Mexico
2012-02-02 13:34:40, -17.765, 167.134, 7.1, 23.1, Vanuatu
2012-01-10 18:36:59, 2.452, 93.208, 7.2, 20.5, Off W. Coast Of Northern Sumatra
2011-12-14 05:04:57, -7.517, 146.766, 7.1, 121.2, Eastern New Guinea Region. P.N.G
2011-10-23 10:41:21, 38.691, 43.497, 7.1, 16.0, Eastern Turkey
2011-10-21 17:57:16, -28.998, -176.182, 7.4, 32.9, Kermadec Isls. Region
2011-09-15 19:31:02, -21.559, -179.368, 7.3, 626.1, Fiji Region




Maybe someone forgot to tell the ones in between that they should not have happened. Sort of spoils the 188 day sequence really.

Some towns right on top of that one. Not good.

No technical details yet.
If it was off shore not a problem,I guess.I wonder when the last big one hit that area if ever.

I believe this time they escaped with minimal damage and this is the most important thing.

GeoAzure 7.4
USGS 7.3 as noted already
GeoFon 7.2

Come on guys, you are not trying. We can get this below 7 if we really try.

The Mexican site isn't working off your QVS link page BTW, not sure if the address has changed or its just overloaded.
