Quake Watch 2011

reply to post by BeyondPerception


USGS is now showing two 7.0 quakes in that region. The second one has a depth of 10 km; however, it has not been reviewed yet.

Just as I posted this, USGS removed the 7.0 at 229.4 km.

Ya, my Quake Alert shook again, but it didn't add a new one, it just changed the details.

10km is definitely a bit more worrisome.

You are correct it was a shindo 5. My bad memory!

This was the post with the magnitude details.

www.abovetopsecret.com...

EMSC now have it as a 5.0 but USGS are still 4.9. The green is EMSC.

The USGS description leaves much to be desired. It says near the coast of Honshu, yet for ones in the sea it says off the coast. Not much distinction really.

This event has been reviewed by a seismologist.

I still don't see that one in my database and later stuff has already come in. I am wondering if like the 7.0 earlier there it has been deleted?

The 4.8 has just come in.

Mods can move or delete this if needed. I just wanted something on record in case there is an event in TN.

This morning, I noticed all our clouds were lining up in a relatively straight line. I've never seen them like that before and I am a sky watcher. With all the activity in Arkansas, I was wondering if these are earthquake clouds.

I don't know how to embed pictures, but these clouds look almost exactly like the white lined up clouds on this website: earthquakecloud.files.wordpress.com...

Except that instead of one line, there are several lines all on the same angle with relatively equal clear space in between.

I'm kind of new at this, so am I right or is this some other weird weather phenomena that is happening. We did have storms of insane magnitude last night. We got hit by a tornado just a couple of miles west of us (literally).

BBC reporting as breaking news, 'Two magnitude-7 earthquakes hit north-eastern Burma'. On RSOE EDIS there are images of 2 red squares...
Apologise if this has already been posted.

I hope you are wrong about this, but I can't help to think something could be going on. I'm in East Tennessee (West of Knoxville) & have had the worst time this week with ringing and pressure changes in my ears. It has put me a little on edge.

I have to get out & about and will take my camera with me in case I see the clouds you are referring to.

So would I be right in saying that it is a nice day, reasonably warm?

That sounds just what glider pilots call a 'cloud street'. Basically many rows of cumulus clouds forming, that will get larger and tend to join up as the day goes on. It is called a street because there is good lift under those and you can glide 'down the street' and even go street hopping.

Earthquakes clouds are yet to be proven to exist as far as I am aware.

However, these claims have very little support in the scientific community.

This is because RSOE and the BBC are idiots and neither check their facts.

There was 1 earthquake, registered as a 6.7 by EMSC and a 6.8 by USGS. There was a 7.0 but it was deleted and replaced with the 6.8. Edit: Actually I tell a lie. Looking at my revisions the 6.8 was posted as well as the deleted 7.0, and was first posted as a 7.0 and then revised to 6.8 - See below. So for at least a few minutes there were 2 but no one in Auntie thought to check. Typically of course RSOE has not updated the magnitude and probably never will yet says it's source is USGS-RSOE. They don't source anything! They work from the same list that I do.

I see RSOE have changed it to one. That makes a pleasant change!! Perhaps they are learning.

Ok. Thanks for clarifying.
Guess RSOE is the lesser of evils to go by then...?

Well, I was definately right about focusing on the Indian Plate. But I'm rethinking the cause. At first I had it backward and thought the Indian Plate was on the move. I was wrong about that. It's Asia itself that's reacting. And compression of faults along the Indian Plater are causing the mid-Asian quakes. The India Plate is most likely standing firm and the Asia Plate is acting as a block. I think the question at hand is when does the Indian Plated decided it's had enough stress and dives under Asia. Wow. That could be really big. Who knows? That may take not days or weeks, but could be years from now.

If the Indian Plate is thinking about moving, then we can think of these Asian quakes and precursors.
Or they are completely normal.
Or the faults are just reacting due to the compression from the earthquakes in Japan.

Take your pick.

Personally I would not use Auntie or RSOE for anything (they are Radio Hams after all)

They have their uses as a source of other events perhaps but for earthquakes I would be using EMSC and/or USGS depending really on the areas you are interested in.

For Europe obviously EMSC is better. For the UK you could take the occasional peek at BGS.

All of these are found in the links in my signature.

Great - I'll check out the sites and add them to my faves.

Thanks, I have that Makran quake on the 1945 7+Project page/map/list as an 8.3 Unk Mag, data from NOAA, I still haven't revised the pages from 1948's back with the Centennial List yet, so haven't got any other sources or magntudes for it.
Always handy to get some extra descriptions as well, thats the hardest part, finding descriptions.
I should put the source of the descriptions on too I guess, has only come to light when posting off the Project to ATS, I've forgotten where I got 90% of the texts now

As far as I am concerned that Burma quake is a 7+ keeper

Edit to add: Not to worry - found a thread who's discussion has helped calm my unusually nervous feeling tonight (else I would have thought twice about posting something that is obviously being watched by those on this thread and would've likely been mentioned before I posted I'm sure!).
