Welcome back, Robin!!! We missed you!


Westcoast... check in when you can and let us know you're ok!!!




***Westcoast waves her hand**** "I'm okay guys!!!!"


Thanks for your concern...really. It means a lot.

Epicenter was 200 miles away, didn't feel it. BUT...I am concerned. I think it may be a fore-shock.

I feel so strongly about it that I started a thread....

NEW THREAD

SOOOOOO glad you're ok and checked in with us!!! Thanks, hun!


Now..................... why did you have to go and say what I was thinking (foreshock) *sigh*. LOL Off to read your new thread. Perhaps a cocktail first? (hee hee)

Been a while

EQ Canada are saying 6.3Mw

3 P.M. PDT UPDATE. This earthquake occurred about 50 km off the west coast of Vancouver Island, and 300 km west of Vancouver. It was felt across southwest British Columbia, including Vancouver Island, Greater Vancouver, and as far away as Kelowna. There have been no reports of damage. The last large earthquake in this area was a M 6.6 event on November 2, 2004.
earthquakescanada.nrcan.gc.ca...

Edit: On the lists they have 6.6Mw

Anyway, I siphoned out Gold River on the list and heres the recent activity since 12/8/2011

Interactive Map

timed out but just to add to post by muzzy
 

earthquakescanada.nrcan.gc.ca...
this would be the page to watch for smaller aftershocks, I doubt USGS will show anything under 4.0
i wouldn't expect many 5's might be some 4's, but mostly 3's
Like California there always seems to be time lag of 3-4 hours after a decent sized quake before the aftershocks go off in this area too.

This looks as if it is a small quake somewhere in the area on NIUE - NIUE.AU..BHZ.2011.251

You can see on Raoul Island it is still there but slightly weaker and extended - RAO.IU.10.BHZ.2011.251

On the BHZ channel of SNZo this does not show at all - SNZO.IU.00.BHZ.2011.251

Looking at the LHZ channel I have had to wind the scale up to see the event but you can just make it out. SNZO.IU.00.LHZ.2011.251

I don't know what they do to these plots, i.e. what sort of filters they use to get these very clear seismograms that they use for LISS.

From the VHZ channel I can tell this is a distant quake. The signal is clear - SNZO.IU.00.VHZ.2011.251

Now I did find this one: Vanuatu 5.1 Mb UTC: 08 September 2011 @ 21:03:50. Seems to be the right time and in the right direction to create the progression I noted.

ETA: I looked on Google Earth for the location and found a USGS 'blob' right next to the co-ordinates. Low and behold I click on it and......



I don't know why I did not spot that in the lists the first time I looked this evening??


I find that it is in the mag 5+ listing as a 5.0 and it is a 5.0 in this list: earthquake.usgs.gov...

It is a mag 5.1 on the EMSC lists.

Yeah I seen that Vanuatu one, but it was after the trace on AFI and SNZo.

That Nuie one shows quite well and I think is in the right direction, pulled up AFI in Samoa and its quite big on the BHZ channel www.iris.edu...

but its not so big on MSVF Fiji compared to the earlier 4.9 there
www.iris.edu...
so I'm picking it was either on the Pacific Plate west of Samoa or perhaps on the Tonga Trench

Interesting there are 3 quakes about the same trace size and one slightly bigger on MSVF all before the Vanuatu 5.0, none of these listed, so must be below 4.5.
Still can't figure why so big on SNZO LISS, that would confirm it was out on the Pacific Plate to me

but not too far out, as RAR Cook Islands shows nothing
www.iris.edu...

*BTW having that IRIS_REALTIME file of the stations on Google Earth sure makes it easier to check the various graphs

Too tired! You are right I got 9 pm (2100) and 1900 muddled. 04:27 - I am off to bed.

Anyway definitely towards Niue.

Hello Robin,
A few weeks back the BBC - in London uk - ran a well detailed programme ref; 'The Core' of the planet. Did mention such to Puterman, who returned a list of better detailed sites etc. Anyway the reason for writing is how present discoveries explained the possible formation of the Core, plus CRYSTALS, something you spelt out and i fully wgreed with sometime back.


www.bbc.co.uk...
One page worth reading and as said , Puterman may return more detailed URLs, Hope all is well your side of the pond
farewell for now

Sorry if this isn't appropriate, but satellite communications have been disrupted in the last few minutes at least.
Solar activity .

I'd just like to say the you guys/gals are awesome.

This is a useful and valuable resource with level-headedness.

Sorry: RWC and Al K.Hole, but the fact remains that this is an interesting thread and informative and valuable.

Just wanted to get that out there.






Sorry.

Very much appropriate actually and thanks for posting. From which site(s) are you getting this information?

Many of the seismos are transmitted by satellite and for some time now I have been convinced that certain signatures are artefacts of the transmission so anything that aids in tracking that down is of interest.

That's a very logical explanation - thank you! I have one follow-up question for you, or any other veteran quake gurus. I assume that the reporting system/software that does the rounding of coordinates is not new, so I am compelled to ask if you have seen this pattern before? If not, what is unique about this small quake swarm?

I appreciate y'all's patience with me. I'm trying to educate myself in the ways of seismology.


I just did this map of 5 years worth of quakes offshore Gold River BC, if you zoom in to 5km/2mi you can see the grid pattern.
Again, EQ Canada also only have 2 decimal points on their co-ordinates
Gold River Quakes 5 Years

Edit: zoom out to 20km/10mi and it looks "normal"

Perfect muzzy, and absolutely brilliant. I have noted all the links as that is the best example of gridding I have seen.

With your permission I shall use that in the future.

Hi Puterman,

I was hoping you could answer a question for me. Or anyone else with knowledge of seismicgraphs.
Noticed that 3.2 off Oregon. Was wondering if that is what is affecting the seismic servers in the midwest?

sure no problem .


I didn't see the grid at first myself until I zoomed in.
Not sure why there is a wedge shape to the locations, maybe EQ Canada have their locations/names worked out by quadrants of a circle, I just used the words "Gold River" when sorting the data
