This posting is short on comments and short on the Rest Of World maps but I needed to get something up quick as there is a tsuname risk to various places.
So a h/t to Baa Humbug in https://chiefio.wordpress.com/2010/12/24/quakes-7-4-off-japan-iwo-jima/#comment-10377.
You ought to “click through” to the prior posting on quakes for the global maps. It sure looks to me like a lot of places are “getting action”…

Interesting reminder of the history… I saw a “possibly related” that looked interesting and followed it.
From back in October 8, 2009
I’d remembered some 7.x from Vanuatu but had forgotten it was a 7.8 size. I think I was just remembering the 7.3 from August 2010 and / or the 7.2 from May 2010…
Remind me not to build a brick building in Vanuatu…
Multiple 7.somethings spread over a couple of years has got to be nerve wracking…
Putting “Vanuatu quake history” in google as search terms gave an odd looking result about a page down labled “timeline results for Vanuatu quake history“. Capturing the link gave this:
http://www.google.com/search?q=Vanuatu+quake+history&hl=en&prmd=ivns&tbs=tl:1&tbo=u&ei=NsoWTYenMou8sQOw_an7Cg&sa=X&oi=timeline_result&ct=title&resnum=11&ved=0CD0Q5wIwCg
At the top of that link is a chart that looks like building frequencies of references inside of Google. Interesting… It seems to show a building pattern of interest. One wonders if it is a useful indicator of quake activity…
And I don’t like how it’s building to a creshendo…
When your aftershocks are 6.6 and you’ve had more 7.x in the year than I can remember, somthing is going on. I don’t know what it is, but …

I heard briefly on the news that Christchurch (NZ) has had some strong aftershocks. That’s 10 months after the quake earlier this year.
magnitude 4.9 on boxing day http://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=10696807
here is a list of the last 30 quakes on the “Shakey Isles”
