Quake Watch 2011

After seeing the waveform (I pulled it up in GEE) and phase data of the Japan 5.3, that will probably be reduced down to the 4.9- 5.0 neighborhood. But look where it happened:

Thanks for the heads-up. I have posted one of my typically longish replies there , but at least it includes a little piece of referenced information that might be useful to some.

We had a little quake in the little old Czech Republic today. I'm posting it because it's not in a place where we so commonly seem to get them. (Most of ours are either out west or up near the Polish border.)

Magnitude ML 2.2
Region CZECH REPUBLIC
Date time 2011-11-16 12:22:53.4 UTC
Location 50.45 N ; 14.12 E
Depth 10 km
Distances 47 km NW Prague (pop 1,167,050 ; local time 13:22:53.4 2011-11-16)
10 km W Roudnice nad labem (pop 13,075 ; local time 13:22:53.4 2011-11-16)

yes indeed
I didn't have time yesterday to check BMKG

Date 16/11/2011-6:42:34 UTC+7
Magnitude 6.2 RS*
Depth 57 Km
Location 5.25 S 140.4 E
Information:
The quake's epicenter was on land 34 Southwest Oksibil
Felt (MMI):
III Tanah Merah, II Merauke, III Wamena, IV Oksibil, III Sumohai (Yahukimo),

*RS = Richter Scale, ie ML

I see EMSC have 5.8Mw, and there are a lot of 6 magnitudes on the phase data.
If I was collecting 6+ events I'd have that one

Interesting trace on my local station SNZO, looks like a butterfly , not sure what that means, perhaps it was two events

SNZO (Karori, NZ) 5406 km SE of epicenter

compare with the closest LISS station
PMG (Port Moresby, Papua New Guinea) 877.8 km ESE of the epicenter

Muzzy is the Virgin Islands "swarm" normal? I know that Puerto Rico is usually active just saw these quakes and I am wondering if that many is the norm. Thx in advance.

Virgin Islands are always shaking - one day it's going to snap - triple junction plates in the area are an understatment. Sorry, can't give you the links at the moment buts give a good ole goolge search. BUT THEN - we have all the activity off the coast of Africa - Something to keep an I eye for sure - Maybe Mr. Puterman could give us a look see at a happy little graph? :-)


Side Note: Your Signature - falls in a long the lines of my Dad's way of thinking - rest his soul.- but crude he was, he did make me shake my head a number of times - rest his soul - - when I left the nest go make a move at 17, 250 away he says to me = If you can't dazzle them with brilliance, baffle the with bull st-t. Yeah, That was my
Dad.

quite high numbers but not out of the ordinary when considered over the years, have seen swarms like this before, "Settlement, BVI": is stamped in my brain
See there's a 4.9 in there

Not prone to big quakes though, in the last 101 years only 2 quakes above Mag 6 within 300km of that one

Mr. Muzzy, sorry didn't mean to not include you in the above post. Maybe can you do us a Happy Little Graph

Best,

P.S - I Like Graph Compitions-

That NZ swarm I posted this morning was just one of two swarms, and turned into quite a rumble

interactive map of those
list for 16th Nov UTC NZ

I'm not so good at USGS data processing without Firefox, Chrome won't let you "select all" off the USGS search results page and there are thousands of lines to copy into Excel to make a graph.
I'll leave that one to the expert.

Is this telling us something?

Saw those and thought the same thing. Hope that pressure isn't building and snaps...

Hi, Diamond, I noticed this too a moment ago. 3 quakes over an hour or so period. May just be a casual swarm, I do hope so. It seems the NA/SA side of things appears more active these past few days.

reply to post by murkraz
I hope too that nothing will happen there but EQ dog bite usually on Friday!

Thanks to both of you. I did a google search on "Virgin Island swarm" and Yikes most were crazy. One site even connected the recent quakes there to the prophecy of Fatima! Anyway I did find this which helped a lot. I guess the quakes just seemed weird for some reason but it does look like its normal as you both stated.

Persistent seismic swarms northeast of the Puerto Rico-Virgin Islands (PRVI) tectonic block have been recorded and documented for more than a decade. The heightened seismicity typically lasts for days to weeks and consists primarily of hundreds of Ms < 4 events, but events up to Ms 6 have been recorded. The active region (sometimes called the "Sombrero" region although it is far from Sombrero Island) is located on the forearc of the Puerto Rico trench north of the Virgin Islands. What exactly causes the heightened seismicity in Northeastern PRVI is unclear, however some suggestions seeking to explain its occurrence have included a tear in the subducting North America plate and stress relief associated with pre-existing ridges, reflecting either asperities in the subduction process or re-activation of ridge faults.
