latest from China
interactive map March 2013 up to 22/03

what a mission that was, 5 attempts, ended up having to load the file to Dropbox manually, wouldn't go in directly from Google Earth
still a few bugs to iron out with this W8, have got rid of the adverts by installing a blocker add-on for Firefox, was probably my own fault I had to install a new Firefox and it didn't have the add-ons I had before, after a while you forget how customized your browser can get over time.

This article in Science News, titled Quakes in Slo-Mo, gives a good overview of slow-slip and tremor.
Read it here

It talks not only about Cascadia, but slow-slip in Japan, New Zealand, Mexico, and Costa Rica, and how this was a missing component in our understanding of subduction zones.

Speaking of subduction zones, I noticed this small mag 3.2 in NW Washington was 41.3 km deep. That could be on the subduction interface, or in the subducting plate itself. My guess is the latter, because of its location near the JDF arch. I'm waiting to see if they post a focal mechanism.

A bit quiet but not very quiet IMO

Didn't say much about NZ that I could see, the slow slip occurs here along the East Coast North Island between Mahia Peninsula and East Cape.
Interesting about the Cascadia thing, I remember that, the tremors went north west to south east, how does that relate to the 7.5Mw at Queen Charolette Island in Jan this year,I wonder, maybe the subduction process pulled/stretched the JFPlate in so far under the AM Plate then it snapped, back up where the tremors started.

I think you got the axis text wrong on the 5.0+ per day, only 1 quake above 5 on USGS for 21/03 and 2 for 20/03
not 10 and 20
need to lose those zeros ?

Not a lot about New Zealand, except that there is a group trying to get funds to drill through the ocean floor directly into the subduction interface.
They state slow-slip in NZ is shallow 5-15 kms depth, whereas in Cascadia it is 25-40 kms deep.

Mr. Dal Stanley had this to say regarding the Queen Charlotte quake and tremor, near the bottom of his website on Cascadia:

The first, a M7.7 off Queen Charlotte Island appears to have been a reverse thrust event with oblique motion of the Explorer Plate against the region where subduction thrust style of tectonics merges into the area of pure strike slip between the Pacific plate and North American plate. This region is shown in the figure below along with a slightly more recent M6.1 event on the southern margin of the Explorer Plate. These two events suggest that stress was relieved on the north end of the JDFP subduction zone. The recent earthquakes may reflect a northward focus of stress after the major tremor episode of 2012 which started under Vancouver Island.


There might not be a relationship between the two earthquakes and the intense cyclical tremor event of 2012, but this is the sort of relationship that needs to be explored to understand any warning trends for the next megaquake.



@PM
Thanks for the reality check. I can rely on your charts to reign in my doom mongering.

China back maps

15 interactive maps, going back to January 2012 now.

Geez those mountains west of Chengdu, Sichuan get hammered

surely they can't still be aftershocks of the 2008 mag 8 quake.
The way the China Earthquake Networks Center is set up the catalogs are spaced by dates and 2008 is the start of the most recent catalog, the next oldest one starts in 1969.
This has raised my interest now, to see what the activity was before in those mountains.
I'm having trouble with the data being in degrees and seconds, all the batch convertors (to decimals) I have tried don't like it because the minutes are missing.

I think we are going to get an increase in the number of quakes again, it's about time.

Um 10 and 20 is the right hand scale which relates to the cumulative. The left hand axis (as normal) relates to the daily number.

Whilst writing has anyone noticed that El Hierro is going again?

Kicked of with a 3.8mb on the 17th



And the left hand axis is the count and the right hand axis the cumulative count

I did.
I posted here , but suspect it wasn't seen by many people, because you have to log in to see the pinned threads.

Still going strong. It looks like the activity is moving west over time, but still relatively deep (16-20km average depth).

Leading up to the Sichuan Mag 8.2 Ms there wasn't much going on in the Sichuan area, but elsewhere in China was rockin' pretty good.
Jan had two Mag 6's near Gerze, Tibet (Xizang) a 6.8 and a 6.2
Feb was pretty quiet with just two mag 5's in the whole region, but notably a 5.0 SW of Chengdu at Garze (about 150km SW of where the 8.2 was to hit in May.)
March had the 7.5 in near Lake Galu, Southern Xinjiang (NW Tibet) with heaps of aftershocks well into September.
April saw a 6.4 off the coast of Taiwan
then the May 12th 8.2Ms (7.0ML, 6.4mb) interactive map
all 2008 China maps
So it is quite probable that the quakes we are seeing today in 2013 along that range of mountains near Chengdu are indeed STILL aftershocks of that massive 8.2 in 2008.
amazing

working on 2007 today

sorry about that, didn't notice it wasn't working, the word "link" looks like its all set, but there is nothing there, strange.
Too late to edit now, curse of the ATS Forum 4 hour rule ( which is actually on 2 hours in reality)

See Putermans post (thanks Pman
) with the page link.

I will put a link at the bottom of that page to the other years, its too many maps to put 4000 years of data on one page so I have decided to make a separate page for every 2 years, that will be 24 maps per page. Earlier stuff may end up as yearly maps or even decade maps as there are fewer records from then. We aren't all on hyper speed broadband eh.

not where I expected... but we will see. Maybe we will see some more quakes today. (I would go for Puerto Rico or something or Papua New Guinea

Well I don't know about you but this one was right where I was expecting it.

Unfortunately our only eyes on the area, G.SANVU seismograph station, has been off line for two days now but prior to that there were lots of small unreported quakes. I have checked in BUD and all channels stopped on day 81 (Friday). I hope this is not a permanent state!!

Begs the question where did they get the quake information? Well not SANVU anyway

USGS Phase data

ETA: MARNC is Mare, Loyalty Islands, New Caledonia and NOT MARN in Italy. The right hand column truncates the 5th character.

HNR is the closest we do have access to and is Honaria in the Solomon Islands

Click for the bigger picture


You can see the quake rumbling slowly through. HNR is quite a distance from Vanuatu. The signal after 4 is NOT the Kuril quake, it is something local.

Forgot to add: You can see the VANUATU seismograms as far as they go here

 

PuterMan speaks with forked tongue

I really must keep up to date with the _REALTIME network. The problem is that I have a bit of difficulty remembering all of the 2600+ stations in the network especially since they seem to be increasing quickly. Not so long ago there were < 2000.

The ND (New Caledonia broadband network) is in the _REALTIME virtual network so we do have other eyes.

Maybe they just stopped online service, but are still active? I don't know, just an idea
