I'm doing a bit of research into Magn7+ earthquakes ona Global scale.
I'm using USGS back to 1973 when they started out, with cross referencing with NZ Geonet, EMSC and Geofon.
Before 1973 I will have to rely on NOAA. (National Geophysical Data Center)
They have a catalogue going back to 2150 BC

www.ngdc.noaa.gov...

There must be other sources


I've started looking at obsure Networks to see whats there, found this one this morning, its part of the Russian Academy of Sciences, but relates specifically to Kamchatka, which has more than its fair share of 7+ quakes.
I already found one Mag 7.3 in 1971 that wasn't on the NOAA list

Heres the link, may be of interest to some

This could be very interesting, especially if there are more as it would possibly prove that actually earthquake frequency is decreasing.

Thanks for that.


Edit: I assume you have tried ANSS?

Save you the grief: Here is the file (CSV). This is all 7.0+ quakes from 1898 onwards

OMG I never even looked at ANSS, I thought they would have the same list as NIEC so never bothered.

I downloaded your link to the Search you did for me, thanks for that


This is going to be VERY interesting, taking a look at just one year 1971, I see 4 more events that I already had, and I had 4 more other events than ANSS had


Holy Cow I'm going to have to start again


Heres the work in progress, I've only gone back 40 years so far .......

The icons load slowly but they do load on.

while the decade graphs tell a story, I'm not sure the yearly graphs do much??? there is no pattern to what month they occur

Something new from Geonet for those who use Google Earth.
I changed the icons to my colour codes
aqua 1-2
green 2-3
grey 3-4
yellow 4-5

NZ Quakes 18-19 June UTC

There seems to be a trick to getting the sliding sequence working.
To get the sliding time tour to work you seem to have to run the slider to the end to get all the events on the map, then the slider can be split in two halves, take one half back to the start. Then you can click on the run button (2nd from left) and it goes through the sequence, leaving old ones there.

Excellent work so far.

Keep on going!! I will see if I can find any other sources.

I did a cross reference using Excel for the 1970's to compare the data ANSS and NOAA as a starting place, I found 4 more in 1970, 3 in 1971, 1 in 1972 and 1 in 1979. So apart from the 1979 one, which was a 7.0ML SW of Kodiak Island Alaska, and perhaps had a lower magnitude on NOAA that didn't get picked up on my search, it looks like I'm OK with what I have already done.
The ANSS data seems to match NOAA for the period 1973-1979, so maybe I won't have to redo the whole project. Thats a relief

I will check anyways.
Pre 1973 the ANSS data will be most helpful though.
Thanks again for the heads up.


Do you have any idea whats with the British Geological historical data?
I got a page off their main page which has a lot of data but they seem to just show intensity that quakes were felt in particular places in the UK and Ireland, they don't show where the actual quake was.
Maybe I am missing something here, or am looking at the wrong pages.
Any 7+ in the UK region historically? perhaps in the North Sea or out near Scandanavia that the other sources might have missed?

Is 33km a 'default' depth do you think (EMSC)?

I notice that the USGS data has it at their default of 10km (of OMG 10 Russian nukes fame) and so do Geofon


Do you have any idea whats with the British Geological historical data?
I got a page off their main page which has a lot of data but they seem to just show intensity that quakes were felt in particular places in the UK and Ireland, they don't show where the actual quake was.

Well no 7+ in my lifetime so that takes you back to before 1950, and somehow I don't think there are any in the UK or Ireland. Ireland just does not do earthquakes except small ones in Clare when the poitin is wearing off.

Apart from that I guess there were probably some in Iceland for sure and since the one and only 'international' seismo (II.BORG) is relatively recent one could have been missed.

Edit: I have managed to find out that the largest ever (reliably accurate) quake recorded in the UK was on the Dogger Bank - a 6.1ML, in 1931. (Source: British Geological Survey)

They often are on the mid Atlantic ridge in that area. Just right to upset the Global Seed Bank!

I don't know - I live in the Catskill Mountain of New York State. My building just shook and there was no wind of big truck going by. I think we just had a earthquake :-)

Thats a big one for that area, I see on EMSC they have the depth at 2km, thats not a default.
Can't get Earthquakes Canada up on the Web, probably overloaded.
all I get is
"June 23 1:45 pm Eastern Time - A moderate earthquake has occurred in the Ottawa-Montreal region. More information to follow"

I think the 5.5 mb reading will stand, EMSC data is showing reading in the high 5's and low 6's ML

That 5.0 USGS is GS ( Goober Scale)


Full Moon in 3 days and Apogee ( furthest distance) Jul 28 23:51 405,954 km F+2d22h in 5 days !!

Quite a few deep quakes in New Zealand yesterday, interesting line of minor ( 3.4's) between Tauranga and Taupo.
Also a 563.4km deep 5.5 mag quake near Fiji

Absolutely no idea what that is. It is NOT the Canadian quake. You can see that here as the blue event, which is completely overshadowed by the green.

YLA.WY..EHZ.2010.174

It seems to be all through the park but I can find nothing that matches it for time.

Maybe they have not issued the details yet?

Edit: Actually I think it is the Canadian one ringing. The trace seems to be continuous. You can see it a bit more clearly on this plot YMS.WY..EHZ.2010.174

That seems an awful long time to all be one little 5.0 however so....???


Edit again: I am going nuts!! These recorders with 5 divisions instead of 4 confuse me. It does look as if that is all the one Canadian event.
