Good luck getting all caught up when you get home!!!

Thanks for the link! An interesting read!
Although some of it is waaay over my head!

Oh, who am I kidding??? A lot of it is!!!
Love the graphs & figures. I'm a visual learner.

One thing that was mentioned was water density variation.
Something I hadn't thought about in a long time!
I still have a lot of learning to do!

I wish they would have had present day monitoring equipment back in 1960.
I would have loved to be able to see the stats from their big one.
Watching Japan's develop was mesmerizing!
Although I hope they never have another one that big!

I'm back in Kapitistan! And back on Broadband!!
Really missed being able to surf the Net for earthquake info. Lots of catching up to do
this article is interesting;

The largest slow-slip event ever recorded in New Zealand
The Kapiti event started in early 2013 and is still going on. It is New Zealand’s largest slow-slip event ever recorded, equivalent to a magnitude 7.1 earthquake. We have 12 years of records in this region, which show three Kapiti events, each occurring roughly every five years. So far, this current event has as much as 15cm of movement over an area approximately 100km by 200km. The previous event in 2008 was equivalent to a magnitude 7.0 earthquake, but the movement was more concentrated: 30cm of movement over a smaller area near Kapiti Island. The 2013 slow-slip event evolved over the course of the year, moving north-eastward towards the North Island, with movement diminishing in late 2013-early 2014.

So this was going on before the Cook Strait M6's series and was most intense during that July/August period then easing off, so had to be part of it, although they don't mention that.


Really a good article, worth a full read, discusses the relationship between the Kapiti slow slip and the Jan 2014 Eketahuna M6

The fault in the Eketahuna earthquake would most likely have ruptured in the near future, but the added stress may have caused it to rupture earlier.
Slow-slip events do not universally increase stress on surrounding faults, they also relieve stress in some areas, and therefore may postpone an earthquake in an area of decreased stress.

16 day New Zealand update summary
muzzys rule running at 50/50 for May, energy released on the 8th UTC fell to 9TTNT but didn't result in a M5, but the Kermadecs did have a M4.6 and a M4.9 on the 12th UTC and 2 more M4's on the 13th UTC
The 17th UTC fell to 2TTNT and with no mucking about there was a M5.3 the next day South of the Kermadecs
Others;
Eketahuna 4 months on from the M6.3 is down to M1's and the odd M2, except for a 4.25ML on the 16th UTC
Cook Strait 10 months on from the 2 x M6's is still spitting out about half a dozen M1 and M2's each 24hr period
Also on the 12th UTC (same day as the 4.6 and 4.9 Kerm quakes) there was a small swarm of 7 earthquakes on the western shores of Lake Rotomahana in the Waimangu Volcanic Valley, the biggest being 2,33ML map
And on the 15th UTC a 12 quake swarm in the Wairakei Geothermal area north of Taupo, 5 x M2's a 3.06Ml and 4 x m1's map
Also on the 15th an unusual 4.77ML quake off the West Coast of the North Island map (may be an error)
Not a heck of a lot happening down the West Coast of the South Island/ Fiordland on a daily basis, although cumulatively it is looking pretty normal, except on the 6th UTC an unusual line of 4 x M3's up through the region, Dusky Sound, Te Anau, Mt Aspiring, Jackson Bay map
Generally overall pretty quiet

Welcome back home, Muzzy.
The slow-slip link you gave is great. I'd rather experience a mag 7 over months, instead of seconds, anyday.

^^^^^^^^^^^^^^

This is how we do shallow magnitude 3.2 Mb earthquakes...east coast style:
lol, 877 "did you feel it reports".


usgs

Here is a link to the nearest seismogram (vertical movement): TA.S58A..BHZ

I didn't feel this one, but my cat got right in my face and started yelling at me when it happened.
kitty.

thanks Olivine.
Quite shallow that 3.2, depth=1.1km (0.7mi)
Mine related??

a reply to: Darkblade71
as suspected, down to 5.9mww

Was just checking due to this thread, which may well be a hoax. www.abovetopsecret.com...

Is it just me or does Japan look very quiet at present.

Looks pretty normal, usually around 200 quakes per 24hr period, but the TTNT energy released is low, no big quakes
last M5 was on the 18th
Japan Preliminary data for 21/05/2014 15:03:00-22/05/2014 15:08:49UTC
mag1= 153 , mag2= 53 , mag3= 10
mag4= 0 , mag5= 0 , mag6= 0
total= 216 total energy released= 15.772 TTNT

That Topic doesn't say what Time Zone, just 10:30am 21st May, I'll go take a look at both JST and UTC as it should be in the JMA Reviewed Data by now

a reply to: muzzy
interactive map of JMA reviewed earthquake data earthquake for Japan, 20052014-21052014JST which covers 10:30am 21st May in both JST and UTC, centered on Kume Island
No seismic activity, which discounts both volcanic and nuclear activity, even a big explosion, must be a fire

Muzzys Rule back up to 66/33 for May
TTNT energy released on the 21st was down below 10, at 7 TTNT

My whole family definitely felt & heard the 3.2 the other night in Virginia, as did most of my neighbors and coworkers. We're 27 miles from the epicenter

One thing I did get done when I was away and offline was to process some ANSS data I had downloaded prior to departure
Continental United States, Alaska, Puerto Rico and Hawaii maps updated February through to end of April 2014, just published now
Feb and March numbers quite high,
Feb 14% higher than average probably due to that Mammoth Lakes swarm
March 10% higher than average likely because of the offshore Eureka 6.8Mw aftershocks and the tail end of the Mammoth Lakes swarm

What are the odds of two quakes happening almost simultaneously on the same ridge?
