Quake Watch 2013

Don't really know if this is significant or not, but here is a 5 mag right on the junction on the Indian ridge.

Puter, it looks like to me that the entire plate is now moving together south. If true large quake can probably be expected in North Pacific.

SO why do they call it mid Indian ridge and also the junction, is it because this time is right in the center of the intersection, thus junction?

I hope I am making sense and not appearing as some goof ball. I have to ask though. lol

Does it mean anything in the EQ world to have a quake here? Other than there is a quake there? HA!

Seems this is a little subductionish. 5.4 New Zealand!!

Muzzy....! I bet you felt that one.

Yes, the junction is the point where they meet - all the ridges.

Not particularly in my opinion. I guess it would actually be more significant if there were no quakes there. (Stuck)

Yes it is, or as I said before it is very slowly rotating.

More in South America first. The deep Argy Bargy quake is a Chile subduction movement. It will get round to the West Coast eventually.

There has been a swarm of quakes going on for about 16hrs or so in Hawke Bay, biggest in it was a 4.1 up till this one


dangerous spot, scene of the 1931 Mag 7.1 that destroyed Napier, which was the most destructive earthquake in NZ before the Christchurch 2011 6.3

I'm about a week behind with NZ quakes, been in L'Aquila for a week ( on the computer )

USGS not using NZDT I see I did a double take to see if there had been a 5.2 and a 4.8 or if they were the same quake, USGS an hour behind on the NZT


geez there are some high readings on the USGS phase data for this quake
6.0-6.3 near the bottom
where the heck is BYL??? Babylon?
I have a file somewhere with them all on it will have a looksee.


Ha!

This could very well be a foreshock sequence....

Linked below is a list of Peru quakes going back to 1600.

I hope I am wrong!!

earthquake.usgs.gov...


Note the closest city....There were some sevens that shook the area in the 1950's.

Hope you are wrong too!.
Thats an interesting list, although I haven't gone back as far as the 1800's yet on my World7+ project, I do have 8+ on there and that Peru quake doesn't show as a 9.0

Location: Chile/Peru:Arica coast
Magnitude: 8.8 Mw

ah! ha! from the html source that page on USGS about the quake

after I did the 8+map!

nothing is "solution finalised" it seems, even after 144 years!

This was the location that SpaceJockey had a premonition/dream about a Mag 9 quite some time back.

I don't have time to look back for it but it is there somewhere.

Yikes...!

A 9.0, 35km or less would decimate a goodly chunk of land in that area!!

Lets hope that premonition is just that.... a premonition!

I seem to remember that as well.

USGS and GFZ obviously thought this Hawke BAy, NZ 4.8 yesterday was significant enough to create a MTS.
I still don't understand how those beach balls work.
Just when I thought I did they come out with some that don't match the basic models.
And they both had different shapes too.


My understanding from this page all-geo.org... kindly posted here a short while back by someone, says that the USGS one is Transtension (extension+shear), but it is upside down
The GFZ one doesn't fit any of the 5 standard models at all

can anyone explain? or have a more comprehensive link where I can learn about this stuff?

here is the swarm "iconized", as shown on 7days-2013-54 (i.e. coloured by magnitude)

[color=lime](click image for interactive map, opens in new tab/window)

hard to say when it actually started, if you look on NZ 30days Hawkes Bay is peppered with events back to 9-10 Feb when there was a 2 day gap, but the bulk of the quakes on this NW-SE "fault" mostly happened on the 22nd Feb UTC.

Note: these links above are only good for 7-30 days respectively, after that you need to look at 2013 All Quakes/month which are more permanent map links



popped the 1931 quake[s] in with the Feb22 file and this swarm series is NE of the two biguns.

theres a bit of text on the popup tags on the 7's

7.8 and 7.3 jeepers no wonder Napier was destroyed

That's some memory you have their PM!

Feeling something building up for the region soon, possibly by middle-March.

BTW, that 3.9 in Arkansas about 20 min's ago strikes me as interesting...one-off or the start of something?

Man....I hope not. As I am 48 miles away from the southern end of that monster(NMSZ)
