Quake Watch 2012

reply to post by PuterMan


Good morning PM! I have my coffee, my iPad, USGS up, and I'm ready!

I see you have thrown in your opinion regarding the possible volcanic activity.

I'm pretty concerned.... Although my nephews and brother live in Santa Cruz, probability says they will not be effected but never the less many lives could be effected with this activity.

The pattern at Brawley did not work out. It is actually difficult to see if there is much of a pattern because of obvious changes in instrumentation and in what is in the catalogue. The early figures, before 1975, are low and I am guessing because of insufficient instruments. Up to around 2005 no earthquakes under Mag 1 seem to have been included so the tail end LOOKS much higher but probably isn't. I don't have time to look at that right now.

A quick scan of the data by eye suggest that this area always has swarms and these last anything up to a month or more.




Darn it, it just had to be done. Now I must go and do stuff. Point proven.

Good morning. I've had my coffee and eggy-rice.

I'm off to the west coast now driving across the desert through Brawley.

Let you know in about 5 hours if I made it

Ha! You have to make it! :-)

Seriously, I'm concerned .. but now the activity is slowing down I'm hoping the release has been sufficient enough to halt a big one.

Volcanic activity may be the case but honestly have not read that's the case as pf thos morning, so that initial concern has fell to the waist side.

This webpage is being phased out and is no longer maintained. Please use the new Real-time Earthquake Map instead and update your bookmark.

Not a fan of this change, but it is what it is.

I'll probably just be sticking to the Global Incident Map if it still filters USGS.

No, I'm not a big fan either, but I have to say that the more you play around with it the more features you will find.
such as with the Brawley events, the map can do the filtering for you if you set the boxes right, then download the csv file directly rather than having to highlight copy and paste the text and mess around in Notebook and Excel to get the columns set right.
I like the list version because you get an overall picture of what is going on.
They should try doing what EMSC has, where you can preset the filters and get either a map or a list separately.

While its still on this page here is the Hiroo, Hokkaido, Japan 5.8Mw aftershock sequence for comparison to Brawley


looks quite different doesn't it.
I understand that was a Thrust quake, whereas Brawley's are strike slip

Hi.

Here I am on the west coast. Drove through Brawley - - and past Salton Sea. Never felt a thing.

Long boring drive of desert and sagebrush.

Its a highway with max speed 65. Really annoying.

I have been trying to post this screenshot with no success.

So,just take a look at the link and tell me what you think.

The first thing that comes to mind is that I'm hoping this is EQ related, so we can discuss it here.
The second thing that comes to mind when I pull up the coordinates of the nearest station to me is, I'm seeing a very strange array of at least 30 very interesting shapes tucked away in the middle of nowhere that I must go check out if I can get anywhere near them. I'm also thinking that I just burned my Garlic Bread checking them out.
What the heck am I looking at?

Am I missing something here. I clicked on the link and got the Earthscope array stations map. What next?

Is there something significant about these?

Japan may let nuclear plants operate even if faults found beneath them

TOKYO, Aug. 28, Kyodo

english.kyodonews.jp/news/2012/08/179035.html

The Japanese government is considering allowing nuclear plants to continue operation even if faults are found beneath them, provided that ground displacements are seen as unlikely to affect plant buildings, government sources said Tuesday.

The Nuclear and Industrial Safety Agency is planning new safety regulations to approve operations even at plants under which faults are found, despite its current view that nuclear reactors cannot be built above such rifts, they said.

The agency will soon craft new criteria for evaluation of faults beneath nuclear plants based on experts' opinions and hand them over to its successor regulatory authority, which will be launched next month.

Such last-minute efforts by the agency to set new rules have drawn criticism from some experts who suspect the body is creating loopholes in ensuring the safety of nuclear plants. The agency admits that measures to correctly assess ground displacements have not been established yet.

The government has decided to revamp the current nuclear regulatory setup after the agency came under fire for lacking teeth as it is under the umbrella of the Ministry of Economy, Trade and Industry, a promoter of nuclear power. The new regulatory body will be placed under the Environment Ministry but its independence will be guaranteed legally.

Specifically, the outgoing agency plans to classify faults under nuclear reactors into three types -- active faults that could trigger quakes, auxiliary faults that are structurally connected to active faults, and rifts that have weaker power than the other two types.

When faults are deemed to be of the last type, the agency will forecast the degree of ground displacements to be caused by temblors occurring nearby and assess their impact on reactor buildings. When faults are classified as of the first or second type, the agency will ban the operation of relevant nuclear plants.

Governmental research has indicated that faults beneath Hokuriku Electric Power Co.'s Shika Nuclear Power Station in Ishikawa Prefecture and Japan Atomic Power Co.'s Tsuruga Nuclear Power Station in Fukui Prefecture may be active, prompting the utilities to reinvestigate the rifts.

But one of the experts examining the agency's planned new criteria said a fault beneath the Shika plant can be classified as the third type. The view, if found true, could allow for its operation.

Mitsuhisa Watanabe, a professor of geomorphology at Toyo University, said it would be difficult to distinguish auxiliary faults from rifts that have weaker power and that both types could cause displacements just beneath nuclear plants.

"The agency appears to be contemplating how to avoid decommissioning of nuclear reactors immediately before its disbandment," Watanabe said.

Hi PM,
For myself, it just raised curiosity because I wasn't even aware of the project. Now that I've done some reading I'm a bit more informed about what they dub to be 'The largest science project on Earth'. Pretty cool. But yes, now I too am confused about significance of the post.

reply to post by kdog1982

I'm not too familar with these stations. But my understanding is some are permanent and some mobile? Are they always stacked up in these positions?

reply to post by sageturkey


Yes quite an interesting project. The problem is the the virtual network that kdog pointed to is basically of no use to us as none of the instruments in that array have real-time data.

I spend a huge amount of time in the IRIS MDA page, mainly because of the _REALTIME virtual network which changes from time to time and because I have that virtual network on Google Earth so I can see stations close to an event.

You will find the virtual networks around 2/3rds of the way down that page.

From studying the various networks and virtual networks you can soon see that really we have access to very little!

Earth to Johnvidale.....I think quite a few of us quakers would sure like to hear from you when you have a minute.

I am, of course, referring to the Salton Sea situation.

There has been some excellent feedback from the regulars....(you know who you are)

However, it is always a blessing to hear it from a pro!!

Peace

Well,addressing my link,I thought someone would have an answer.

My question was the locations of the monitoring sites and the significance of it.
What it means,I don't know.
I feel it is earthquake related.
