I have come back to this topic again, because it was the one that started me off doing what has become a multiple year research project. The longer I
go through it the more questions appear.
Lately I have been including other magnitude types other then Mw, so the numbers are on the up overall.
So now it's 6.5+ , not 7.0+ that it was to start with. It is those ones that were slipping just under the 7.0 threshold that really got me going,
there were so many of them, and they kept changing, on the data over a couple of years of my research.
Anyway for those that already have been following the Blog significantearthquakes.blogspot.co.nz...
I'm stuck in the 2010's right now, going back and forth as I find more data.
52 new events found for 2012, bringing the total to 95 !!!
It took me 3 days to get this one done, I kept getting interupted, and having to go to work!
I used the search on ISC www.isc.ac.uk...
to get the new data
no restrictions on magnitude type, just 6.5+
and also a lot of new additions to the mag types on the original 43 I had too, mainly from [bji] Catalogue of hypocenters and magnitudes, State
Seismological Bureau, Beijing, China, [dja] Badan Meteorologi, Klimatologi dan Geofisika, Indonesia which is a site I stopped going to as it was
riddled with viruses, and [man] Philippines.
This was the year of the 2 M8's W off Sumatra, and now there are many aftershocks in the 6.5+ range added, mostly from [dja]
Some of the higher magnitudes have shifted up or down 0.1 magnitude, due to more data being available. I don't always pick Mw, but if it's there I'll
use it. Same if one of the sources says 7.6 when the majority say 7.2, I'll use the 7.2 as the primary magnitude for the list.
in summary for the new 2012
now I'll need to go back and do 2013-2015 and do the same, as I forgot about using ISC when I did those.
I hope readers can follow the [codes] it can get pretty confusing, you need to keep the 'About" page open in another tab to keep checking what they
heck they mean, after a while you get to recall the source by the 3-4 digits.
