Two, USGS is saying the second is 6.2 and the first was 6.5.

I didnt see a tsunami report? Any news on that? It was pretty shallow....

I'm curious of how good their gear is regarding quakes down there...

These could be lower or higher in actuality.

...And here are, the receiver is responding to the sender. A quake near the N pole now.

Also there is no tsunami threat based on the area so says the Ptwc.

6.7 quake, only 2 miles down and no tsunami? That strikes me as odd. Please educate me on how this could be.

There will be movement of water but none that is threatening to anyone in that area or outside of it from the sounds of it. It's under 7, if it was a high 7 I would be looking at the travel times. I didn't notice that it was at 2km in depth the first time around. They say there's a local tsunami threat for anything in 100km of the vicinity. Maybe the statement will be revised, I'm unsure of the threat of an earthquake this size with regards to travel times seeing as it's near Antarctica.

USGS is resting with 6.6 for the first now.

USGS is saying it went like this, two 6.6 earthquakes at the same moment and then a 6.2 to follow. 3 quakes as of a few moments ago.

Update time = Sun Jan 15 16:20:27 UTC 2012

MAP 6.2 2012/01/15 14:21:32 -60.797 -55.999 14.8 SOUTH SHETLAND ISLANDS
MAP 6.6 2012/01/15 13:40:18 -60.765 -55.858 10.0 SOUTH SHETLAND ISLANDS
MAP 6.6 2012/01/15 13:40:17 -60.793 -55.729 1.1 SOUTH SHETLAND ISLANDS

Update: Now we're back to two quakes now. Looks like a USGS error.

Looking at the map, the area is pretty shallow.

They have been reviewed now and it's two events -

6.2 2012/01/15 14:21:32 -60.797 -55.999 14.8km SOUTH SHETLAND ISLANDS

and

6.6 2012/01/15 13:40:18 -60.765 -55.858 10.0km SOUTH SHETLAND ISLANDS

I assume this isn't a subduction zone hence less change of tsunami??

Wasn't exactly the spot, but I've been expecting a southern tip of Chile adjustment to the big one there for quite a while, and mentioned this a while back. This might be it, or these could be foreshocks to a bigger one- I was more expecting a quake closer to the direct south tip of Chile, on the west side near the plate junctions.

To Jerisa:
As to why no tsunami, generally it's going to take a 7 or larger, and usually in the upwards of 7.4+ before they are going to worry about any kind of damaging tsunami that is beyond local. 6.6 (and falling after revision) is just not enough.

Hengil? Try mag 6.5 attributed to water injection for steam.

When was that?
I did a ANNS search and got this back

catalog=ANSS
start_time=1970/01/01,00:00:00
end_time=2012/01/15,00:00:00
minimum_magnitude=5.0
maximum_magnitude=10
event_type=E
delta=0 km to 100 km from (64.18,23.33)
No matches to your search criteria

100km radius takes the edge out past the end of the Reykjanes Peninsula, so if it is outside that distance IMO thats too far to blame on hydro injection at Hengill. I stand to be corrected though, you are not often wrong.

...cause climate change and the next ice age.

Your Reply

Sorry not agreed. The coming ice age is being caused by the Sun and has nothing whatsoever to do with 'global climate warming change catastrophic calamity'. That is just sheer unproven BS.

Unfortunately you don't get to watch all the Nat Geographic TV shows on Climate Change.
I don't believe CO2 is the "cause" of Climate Change but surely its not helping any.
Just in my back yard we have the Ozone Hole.

I was just trying to make the point that geothermal energy production is probably the safest and cleanest.
If anything the only downside of geothermal injection that has been seen here in NZ is the slightly reduced natural geyser activity. Aquifer pollution and increased earthquake or volcanic activity are non issues.

Yes this quadrant has been busy the last 4 days

I thought it might be a ghost of the SSI bigun, but looking right now at the NZ Drums you can see it only shows on the upper North Island ones. (at 15hours ago if you look right now)

You cant see the SSI quake on the NZ Drums, they are set differently for close in quakes. Looking at the USGS phases you can see the SSI one arrived from the south end, (MQZ), (RPZ), (WKZ), (ODZ), (WHZ) quite a bit earlier than the North Island ones

Not converted to Mw
neither was the 6.2, so these are pretty big quakes

FWIW the Russians had

I am Eric Blair. I live in a world more backward, and more absurd, than could ever been imagined in the days after the big war. After a long break from television, I've recently watched commercials, and have concluded that I must have woke up one day in an alternate reality- one degree to the right.
I am addicted to thinking about the future. Don't blame me. It's in the genes. Winters are summer. Summer is winter. The invaders are being invaded. Stranger days, no one can imagine.

Me email headlines are making me dizzy. Since I am rushed when checking my mail, I want to scan and move on. But I can't. A reality I imagined is manifesting itself in a constant hum now. People are making the links and asking the questions. Good people. You were slow. But you are at least rejuvinating my faith in us.

Keep on truckin'.

"BRAXTON COUNTY, West Virginia - The West Virginia Department of Environmental Protection says there could be a link between a recent Braxton County earthquake and a brine injection well."

I used to like reading about earthquakes. I would wonder about this stress and that stress. (hmm, i'm stressed), and this rock and that roll. Wait. How did I start my study in quakes? oh ya@$E@@

Here's some lighter reading without the passionate politics.

www.ouramazingplanet.com...

This one not so light, but informative and thought provoking.

Had to add. Finished my emails and checked the big maps. South Dakota 3M. Hmm. I don't have time to investigate. But, I do know South Dakota sure do love fracking for oil and gas.

(i must indulge myself, i am a terrier. jack russell to be more specific. they ar a dog that can be easily mocked. they are only wee dog, with a big nose. they yap and seem manic. but they are only truely understood when you see them at work. they are the most determined and viscious killers of rats in the world. hell, you get more than one together with some others, they can stand up to a bear.)

Had to edit again. I did a quick check on Dakota. But computer I'm on was too slow and I had to stop. Maybe it's nothing to do with fracking- not sure. I'm suspecting irrigation. Hell, it may be natural. Too hard to tell "these" days.

OOOhh, andhere's another little un in the UK
Just a couple more and it will settle down again
