Quake Watch 2016

5.5 57km E of Shikotan, Russia 2016-05-03 00:00:52 UTC 69.3 km

It looks like the buoys in that area are reporting data that shows increases in water height, but I am not quite sure how to interpret.
I wonder if it will cause a tsunami.

While converting my Japan Template I use for the daily CSV file to create the maps to use squares I did a talley up;
Summary of Japanese earthquakes 2016 to 02/05/2016 14:59:29UTC (23:59:29JST) (123 days);

size, number of, TTNT energy released, % of energy total,
mag~1, 20881, 2.332, 0.0001%
mag1, 15784, 50.78, 0.0025%
mag2, 8559, 725.94, 0.04%
mag3, 2286, 7,684.10, 2.12%
mag4, 369, 25,733.06, 1.27%
mag5, 39, 125,282.19, 6.19%
mag6, 7, 519,128.55, 25.67%
mag7, 1, 1,344,028.02, 66.45%
total, 47,926, 2,022,634.97,100%

There is no use comparing to the same period of other years, as the 7's and 6's might have been later in the year.
So really need to compare full years.

Some ATS visitors to NZEQ 2016 might have noticed the new grid block that replaces the old pies (you would have to be blind to not see them).
This is in keeping with the change to square icons, but predates that change, so I must have had it in mind all along
I just completed the changeover to grid blcoks back to Jan 1st 2016.
I think it works better than the pies, or the screenshot maps of 2014.
An explanation of what they mean is on the About page. You guys probably figured it out yourselves, but random visitors might not.

Near the same area as that 6.6 just abit farther north.

Gerlach-Empire sounds like a location from Lord of the Rings

No not many at all, the biggest IRIS has got within 200km since 1966 is
5.3mb, 59.41° N 147.202° E 2001-01-07 06:26:57 UTC 10.0 km mb5.3
which was about 50km east of todays event.
and about 20 others in the area same as or less than todays 4.7

Thank you for this thread. It was the main reason I joined. I live very close to the NMSZ. But I also keep a close eye on everything.

5.0 SSW of San Paticio, Mexico 10km (6.2mi)

earthquake.usgs.gov...

There was also a 5.5 10km (6.2) in the same place

So, what is this chatter I have been hearing about the swarm at Mt. Saint Helens and it's because the magma chamber is filling back up?

Thank you ! This graphic explains it all....




Hope that worked

SW of Kyushu has kicked back into life again.
When the Kumamoto 6.5 went off the SW of Kyushu series died away, it had been going since the 7.1 of 13th Nov 2015.
Now its off again
Origin time (JST) *, Region *, Latitude *, Longitude *, Depth *, Mw, Strike, Dip, Rake, Varred, Number of station(s), Type
2016-05-07 14:42:13, SW OFF KYUSHU, 31.1N, 129.0E, 5km, 5.4, 96.9˚/203.4˚, 60.9˚/63.0˚, -31.3˚/-146.9˚, 90.5, 7, C
2016-05-07 17:09:20, SW OFF KYUSHU, 31.0N, 129.0E, 5km, 4.4, 91.8˚/218.6˚, 48.6˚/55.8˚, -48.5˚/-126.9˚, 83.6, 7, C
2016-05-07 18:16:02, SW OFF KYUSHU, 31.0N, 128.9E, 7km, 4.7, 110.1˚/206.5˚, 58.1˚/79.8˚, -12.0˚/-147.5˚, 85.1, 7, C

I had to use Aqua system from JMA for the list as their Preliminary Data (PD) doesn't show all these, just a 4.6ML @ 07/05/2016 14:48:20
and the 4.7Mw @ 2016-05-07 17:09:20, as a 4.6ML
but you can see the M5.4 and the 14:48:20 M4.6 on the 100 trace graph below
KyushuWaveform5.4+4.6

Don't know how long this one will continue, the PD from NIED is showing 9 aftershocks in the area of the 5.4, mostly M2's and one M3.8
but the PD can be unreliable


Oh wait, there was this the day before, which I missed (due to the day gap between the PD and the Reviewed data)
Origin time (JST) *, Region *, Latitude *, Longitude *, Depth *, Mw, Strike, Dip, Rake, Varred, Number of station(s), Type
2016-05-06 14:11:22, SW OFF KYUSHU, 31.1N, 129.1E, 7km, 4.9, 98.6˚/193.1˚, 71.5˚/76.7˚, -14.0˚/-161.0˚, 91.8, 7, C
now showing as a 5.0ML on the Reviewed data (and 23 aftershocks before the data reverts to PD)

edit: these new moderate sized quakes are in the eastern quadrant of the SW of Kyushu series

N=31.60544, S=30.95406, W=129, E=129.57413 The majority of aftershocks in this area occured between the 29th November and the 20th of December 2015 with only 56 aftershocks thereafter, on a random basis with several periods where there were none for 5-8 days at a time. The energy released here the third highest of the four sections, but the number of events about the same as the Mainshock Section. The lack of a M5 in this area affected the ER count.

edit2: interesting the Kumamoto series was winding down, to just 44 events per 24hrs, last data reviewed available was 06/05/2016 23:53:30JST

It is also where Burning man is held every year. The black rock desert.

I'm pretty sure the SW of Kyushu and the Kumamoto series are connected, at least perhaps the Kumamoto was triggered by the SW of Kyushu.
I've updated the SW of Kyushu page today, and redone the static maps that had teardrop icons, into squares.
Also on the last timeline graph I have inserted the Kumamoto series (green) into the graph.
It will be interesting to see what happens in the next few weeks.
There are several scenerios;
1. We now get a M6+ back at SW of Kyushu ( the Baths Law event may have been the M5.9 at 23hrs elapsed time, but I am still looking for a 6.1)
2. The 5.0, 5.4, 4.7, 4.6 of the last few days may be the final hurrah/burp for SW of Kyushu and it dies off completely.
3. The 5.0, 5.4, 4.7, 4.6 of the last few days may be the start of an even bigger sized event series in the same area.
4. As activity dies away at Kumamoto it restarts SW of Kyushu and goes on for months with smaller sized aftershocks.
This Kyushu series is now 6 months old.

There are a lot of similarities with our 2010-2011 Canterbury earthquake series which lasted over a year, although here their big quakes are about 0.2-0.3 magnitudes bigger and in a more random order of magnitude. If you combine them together it goes;
7.1, 5.9, 5.2, 6.5, 5.8, 6.4, 7.3, 5.9, 5.9, 5.8, 5.8, 5.5
Canterbury's sequence was
7.1, 5.9, 5.5, 5.9, 5.6, 6.3, 5.8, 5.9, 5.5, 5.9, 6.4, 5.6, 5.9, 5.5, 6.0, 5.5

I must be wrong, because there should have been something big about ten minutes ago. Although, I still think I have the location correct. Mexico just had a 6M but USGS likes to end most earthquakes with a nine and pegged it at 5.9M.

Mexico is having about 40 a day. Magnitudes slightly increasing. This may be good. Depends on the opinion about whether it's relieving stress, or just building it up somewhere else. Maybe Mexico is moving freely and this will put pressure on the north and south ends of the plate. Again, were back at Central America. Or, San Andreas.

Oh, this is just stupid. I think the have the San Andreas all wrong. The real big fault is elsewhere and the San Andreas is just the western edge of a long thin plate. Long, thin, and sharp like a shard of glass. Like I said. Stupid.

Now for something that isn't stupid. Something is happening under Nevada. Again, we have another location experiencing a goodly swarm. This are not big shocks and aftershocks. No, many are swarms. Either there is some large force acting on a large area. Or, there are groups of workers tunnelling under the state making some sort of hidden transportation system.

Maybe there making bases and each swarm point is the digging. Or. Nevada is being stretched and is cracking up.

Sorry, time's up on my post.

Just to prove my point, right now on the USGS, the last three earthquakes that are listed above 4.5M, they're all exactly 4.9 M.

Chile 4.9M
earthquake.usgs.gov...

Fiji 4.9M

earthquake.usgs.gov...

Barbuda 4.9M

earthquake.usgs.gov...

When you read down the rest of the list you get 4.7, 4.7, 5.9, and 4.9 .

I think it's a lazy program the rounds it up or down to the nearest 9

I like rounding off to the 9. Retailers know to round off to the 9.

99 cents isn't a dollar.

3 quite shallow quakes near Cobb California, 2.6 - 3.
Several others below 2.5 for the same area, not reported as significant by USGS but can be seen on RSOE.
Kicked off a couple of hours ago.

Probably nothing, but it seems to me the area is acting a little strange recently, complete silence for a while and now a little swarm in Cobb under what appears to be a geothermal power plant.

Probably nothing, but things like this always get my interest.

a reply to: Rocker2013
Today was a big day for Cobb/geysers area...I live about 15 miles away...there are usually about 20 thoughout the day all Small... .2 .5 1's. Every so often we feel the 3's. But yesterday my map was crazy. 20'all within an hour.

a reply to: Spodeeodee

It was a big day for earthquakes. There were 50 at 2.5 or greater in the last 24 hours.
Usually there seem to be around 20, give or take, sometimes reaching 28 or so.
50 seems like a high number.
