last one was near me, was probably on the road by then, can't recall what time I left this morning it was a blur

another one, "heard" and "seen" this one ("heard" as in the house creaked but its not windy and too early for a frost,"seen" as in my broken table lamp with the lens hanging by a wire was twitching for a few seconds, my seismograph if I'm at the desk , and the Internet went off too.

A potentially sketchy situation, when NZ starts spitting out 5's so close together!!

just making a note

I wonder if this is gonna be another, Here we go again in this area?

Haven't seen your name before, so if you are new welcome to QW 2013.
I see your in your profile is "Location: Paradise", so what part of New Zealand are you in?

If Chile is your interest, you may find this worth a look
Chile eqarchives
2012 is available as well from the 2012 dropdown tab off the main Chile tab at the top.
The data the maps are based on is from Servicio Sismológico de la Universidad de Chile, Santiago Chile. (SSUCH), the EMSC coverage of Chile is just a recent addition to their system and not all quakes are reported.

I find it surprising how few quakes Chile gets per month, when you consider how many biguns it gets historically, seems to be a shortage of mag 1's, could be the type of seismo's they use.

Thank you for the warm wellcoming in your thread Mr Muzzy,the Borg should be here any minute....

And thank you for the links,indeed Chile is situated on the South American continent and it has as neighbours Peru, Bolivia and Argentina.

if this format is available elsewhere on the Internet, pleeeeaaase someone let me know before I go too far with it

maps (monthly) of Geofon (GFZ) Moment Tensor Solutions.

[color=8BB381](click image for page, opens in new tab/window)

One day I'll figure out how to determine the type of earthquake each one is by the beachballs, at this stage its a mystery as there are only 5 main types, but in reality GFZ (and IRIS, Useless and EMSC el al) put out hundreds of variations)
all-geo.org...

ETA:
maybe anyone in the know can clarify if I am wrong
from that July map
Sumatra, Easter Island and Hungary are clearly "strike/slip shear"
Uganda, Jujuy and Aluetians could be "normal/extension" but the angle of the beachball is to the right rather than the left as shown in all-geo.org...'s images
Hindu Kush is "transtension" (extension+shear)
Solomon Is is "transpression" (compression +shear) or it could be "reverse/thrust/compression"
Greece could be "normal/extension" or "transtension"
pretty confusing, the angle of the dark or light sections varies

I would have expected Aluetians, Jujuy, Solomons and Indonesia to all be "reverse/thrust/compression" because they are on subduction plate interfaces, and Uganda to be "strike/slip shear" or "transtension" (extension+shear) because its on the Rift Valley.

I agree with all of your interpretations of the beachballs, but since I am a USGS cottled 'Murican, I would say the transpression=oblique reverse, and transtension=normal faulting with a strike-slip component.

Agreed, that because of their subduction locations, you would think all 4 would be thrust mechanisms, but when I looked at the depths, it makes sense.
1. Aluetians at only 5km depth, is probably due to the Pacific plate beginning it's bend down toward the subduction zone.
2. Jujay at 190km+ depth is probably due to internal deformation of the subducting Nazca plate.
3. Solomons looks like reverse faulting.
4. Indonesia is an upper plate event of which your pals at USGS say (6) Mag 6+ have occurred within 250km in the past 40 years & that they are particularly dangerous.

Nice find of the monthly maps, btw.

reply to post by Olivine

thanks for the conformation, but don't confuse me with "oblique" though, thats not mentioned in the blog writing/images.
There is obviously more to these balls than what I was hoping, I had a look at this once before and gave up.
So yes you need the depth to know for sure, which is why the details are in the popup tags.

"Find" ? I didn't find the maps I created them from scratch, based on the GFZ list, which is linked at the top of the page
As it turned out the little beachball icons there on the list are the same size as what I use on all my other maps 32x32 which is the default size for Google Maps without distortion.

I chose GFZ over IRIS, Useless and EMSC becasue their beachballs are consistant in size and definition.

What lead me to do this was I was getting sick of having to click on each item/line in the GFZ list to see the details, now they are all on one map (per month). Of course even that is self defeating now as I have to click on them anyway to get the details to enter into the html for the popup tags

I'll keep at it as long as someone looks at the page.

As I normally do the first weekend after the end of the month, update the various countries earthquakes for the past month.
Having trouble with Turkey, DDA cataloug won't give me the entire month, the search results keeps reverting to last 30 days like the Kandilli Observatory does. So I'm missing the first 6 days of June.
All the others have been updated, except Colombia.
eqarchives.wordpress.com...

Pretty quiet month globally except for Italy, double the numbers ( 2092 above mag 1), because of the Forzone – Minucciano , Massa/Lucca/Carrara, Italy 21/06/2013, 5.2ML and aftershocks.

Will leave June 2013 behind with the interactive map of the month, June Italy, focused on Forzone – Minucciano

I've given up on using Useless's (USGS) web pages all together , only use ANSS now, and only for Yellowstone data.

Can someone satisfy my curiosity regarding some quakes in Canada?
I am referring to four -4- small quakes at Allenby, just south of Princeton, British Columbia.

The first was a M 2.4, on Sunday, June 30, 2013 21:10:20 UTC with a depth of 0.00 km (0.00 mi)
The next was a M 2.3, on Wednesday, July 3, 2013 21:20:25 UTC with a depth of 0.00 km (0.00 mi)
Followed by a M 2.3, on Thursday, July 4, 2013 21:19:15 UTC with a depth of 0.00 km (0.00 mi)
Ending with a M 2.3, on Saturday, July 6, 2013 17:10:15 UTC with a depth of 0.00 km (0.00 mi)

All 4 quakes lay in a straight line from South to North and with a total distance of 5,28 km (3,28 mi) from the first to the last.

How come a straight line and 0 depth?

Links please?
Probably quarry blasts.
