Quake Watch 2012

reply to post by SeekingDepth
The experts here would have a better answer but isn't that area near some large oil shale operations? As I recall Haliburton and companies like that are drilling all over. I assumed the quake had something to do with that.

Actually isn't there a mining company in Gypsum?

Interesting that there was a dormant volcano near buy.

Lots of 'twins' in three states today!

Never saw it like that before.
There were more doubles, but they all had another quake between them.

Actually in going back & looking, there were five twins yesterday too.
The rest of the week only one or two. And a couple of other little swarms.

also

Well it looks like the decision has been made, and is out of my hands anyway, I just plugged in my usb stick that had all my data for 2012 on it and it is completely blank OMG over 1GB of data lost.
I haven't backed up since the end of 2011 either.
I will be able to retrieve some stuff off the Blogs I do, by converting KML back to Excel CSV files, but basically most of the stuff I have been doing is gone.
Any of the current stuff I was doing for August I will have to start again, such as RAS, Thailand, Chile, Greece, Turkey and Egypt, they are going to be stuck on where they were last updated for a while.

No idea what happened to the usb stick, lately it didn't want to accept files into the main folder and I had been saving stuff in sub folders within sub folders, not sure if it got too much for the 2GB stick. Never had that happen before.
Should have backed it up more often to my remote hard drive storage grrrrr
or to Dropbox for the long term stuff that I update when I get the time.
Luckily most of the World7+ Project is saved on my hard drive, I would have been gutted if I had lost all that.

Hey AuntB,
Yes there is alot of drilling & shale around the area a little more west of this area. I also thought of mines.
Gypsum does have a Gypsum mine in the town. I am not sure if there is drilling or mining up near where this quake was. Just always wondered because this volcano was supposed to be explosive and last erupted just a couple thousand years ago.

Strong quake shakes southern Hokkaido

TOKYO, Aug. 26, Kyodo

english.kyodonews.jp/news/2012/08/178571.html

An earthquake with a preliminary magnitude of 5.9 jolted southern Hokkaido Saturday night, the Japan Meteorological Agency said.

No tsunami warning was issued and there were no immediate reports of damage. There were also no reports of abnormalities at nuclear facilities in two Aomori villages -- Tohoku Electric Power Co.'s nuclear power plant in Higashidori, and Japan Nuclear Fuel Ltd.'s atomic fuel cycle facility in Rokkasho.

The 11:16 p.m. quake measured lower 5 on the Japanese seismic intensity scale of 7 in the southern coastal towns of Urakawa and Urahoro in Hokkaido, according to the agency. It measured 4 in parts of the cities of Sapporo, Chitose and Hakodate.

The quake affected a wide area of Hokkaido as well as northern parts of the Tohoku region, including Aomori prefecture.

The focus of the quake was in the southern Tokachi region at a depth of about 50 kilometers.

More checks on faults ordered under Mihama, Monju atomic plants

TOKYO, Aug. 24, Kyodo

english.kyodonews.jp/news/2012/08/178407.html

The Japanese government's nuclear safety agency ordered Kansai Electric Power Co. and Japan Atomic Energy Agency on Friday to reinvestigate faults under the Mihama nuclear power plant and the Monju prototype fast breeder reactor, respectively.

The Nuclear and Industrial Safety Agency called for onsite investigations at the facilities, both in Fukui Prefecture, central Japan, as there is a possibility a nearby active fault may set off a chain reaction in moving fault fracture zones, or soft earth layers, running under the facilities.

Additional checks have already been under way for faults running under Tohoku Electric Power Co.'s Higashidori nuclear power plant in Aomori Prefecture, Hokuriku Electric Power Co.'s Shika plant in Ishikawa Prefecture, Japan Atomic Power Co.'s Tsuruga plant and Kansai Electric's Oi plant in Fukui.

Tokyo Electric Power Co. reported at a meeting with the nuclear safety agency the same day its plan to conduct a boring survey at the premises of its Kashiwazaki-Kariwa plant in Niigata Prefecture to determine when faults under the facility were active.

There were 2 x 5M July 21 in California, without a larger event following.

Today 2 x 4M down in Gulf...

wujotvowujotvowujotvo pretty well covered this one,
this puppy is going to have aftershocks for sure so I did a page on it.
Hiroo quake

Hows that for a bounce back after losing all my Excel formulas yesterday

By the time I processed these aftershocks there have been 11 more, all micros 1's and very-minor 2's, but I expect a couple of 4's (light) and a few more 3's (minor) within 12 hours. I'll follow it through for the 72 hours and update the map every couple of hours if I can and do a timeline graph at the end.

aftershock summary to 25/08/2012 16:54:53UTC
mag1= 17 , mag2= 7, mag3= 3
mag4= 0 , mag5= 1 (main shock), mag6= 0
total= 30 (incl. main shock)
total energy released= 10,686.035 TTNT

ETA: interesting that NIED Hi-net didn't pick up the main shock, and have it on their list, I had to enter that from the jma.go.jp page

sacramento.cbslocal.com...

Historical events 100km radius from last nights ( depending where you are) event. Data from ANSS
goo.gl...
Zoom in and see there was a 5.1 on 15/03/1993 03:35:06 just 100 meteres from todays event at similar depts th of 55.5km.

Networks were quite astray in their plots of the main shock +/- 25.6km
I'll take JMA, its their back yard after all. And the aftershocks are close by too.
goo.gl...
I linked this one to the Google Earth version inside Google Maps, takes a while to load up but has text tags on it. I plotted LDEO as well but they were 100k off way down under the sea off that pointy bit.
Another 24 aftershocks since I posted here last, I put 17 of those on my last update a few hours ago, new KML address so the map doesn't keep loading the old map by default. A/s seem to be spreading NW and SE of the main shock. Still small ones.

ETA: just had another look at the whole refreshed NIED Hi-net list, they have slipped the main shock in at ......

WHEN, LAT, LONG, DEPTH, MAG
2012-08-25 23:16:16.836, 42.3079, 143.1654, 57.7, 6.6

pretty precise co-ordinates, to 4 decimal places, not sure why the high magnitude.

JMA are saying 5.9ML again, I'm sure it was 5.7ML this morning,
wujotvowujotvowujotvo said it was 5.9 to start with, I thought it went down afterwards, maybe I'm cracking up.

I am cracking up, had 5.9 on the maps all the time, just wrote 5.7 in the text for some reason

Thank you for the info! I'm about to check it out further..... I see there IS a tsunami warning?

From Earthquake Report.... earthquake-report.com...

Very strong deep earthquake in the Molucca Sea A very strong M 6.8 earthquake occurred in the Moluccas sea (Indonesia). The earthquake was felt is a wide area in Indonesia and the Philippines, mainly because of the deep origin of the hypocenter (+100 km reported by USGS) Based on our experience , earthquakes from this type are mostly harmless and will NOT generate a tsunami. A radius of many hundred km means that the areas who will have felt this earthquake are Mindanao (Philippines) and Halmahera and Sulawesi in Indonesia. The epicenter of this earthquake is in the middle of the sea at a safe distance from the nearest island.

Whoa!!! Southern California is shaking and baking.... earthquake.usgs.gov...

I just saw this too...... Lots of activity going down and I really hope they stay safe!

I'm not liking this at all..... A bit concerned ....but hopeful.

I'm counting 33 in the last 2 hours.
And the count is climbing steadily.

Wow! Do you happen to know if this is the same place that was swarming a couple of weeks ago?

reply to post by MamaJ

Are you talking about the ones near Yorba Linda?
If so, not the same area. I do know that this area below the Salton Sea gets quite a few swarms, but it's been awhile as far as I know. I'm counting 38 now in this swarm.
