Quake Watch 2011

PuterMan & Muzzy;

Because you are much better than me with these modern instrument readings;

I wonder if you could check the depth of this latest two bigger quakes. You know I saw often the reports for Eritrea were 'adopted' to 10 km depths; while closer stations in Yemen and Djibouti did report depths of 2 km or less. It would be an interesting issue to know how deep these latest two quakes really were.

If you don't mind?

What about Acoustic sound files right here SWS of ChCh?

I do not know if this was posted here before; can't remember seeing it. Probbaly long time, thus allow me to post this link again for those people like me that might have missed it.

This website/link/program is facinating and scare the Blue Moon out of me.
You have many options, last day, last 7 days . . .
From 4 Septemebr 2010 = 7,582+
From 22 Feb 2011 - 3,150+++
Last 7 days = 96.

Click the boxes for 'Sticky Dots' and 'Scale circles with map'; select your period and sit back.
Imagine being on land there and experience the cold chills of true horrow coming up.

Abother big 5.3 aftershock just hit CHCH a couple of hours or so ago:

Bit confused here! Are we talking about Eritrea or New Zealand.

Sound for NZ I had an attempt some time ago and to be honest I have forgotten how I did it, but I do remember their data is the reverse of IRIS (little-endian instead of big-endian or may be the other way) and I had to rewrite my program to cope with it. Just need to know which particular period you want the sound for and I will have another go at it.

The Horror of Christchurch

There are quite a few sites covering the Canterbury sequence, some clever IT people out there.

Geonet's site has advanced in leaps and bounds since the Sept 2010 7.1 with user friendly interactive stuff on their page www.geonet.org.nz... starting from there there are links to other pages with aftershock forecasts and lists of significant events.

Also this site which I check quite regularily quake.crowe.co.nz...

of course they are only improving on the orginal Muzzy Maps that I was running prior to the "Big One" for the whole of New Zealand.
Not as flash with the timelines, but you can see each days events and quickly zoom down and get the details off the markers.
I ran a page of all the aftershocks for a few months after Darfield, but being just a Blog page it took forever for the markers to load to the maps so in the end I caned it. Now I'm just doing 7 Days and 30 days events.
I can't keep up with the number of aftershocks now after the June 6.3, its just a hobby done in my spare time and I do have to work during the day if its not raining. So at times my Blog can getup to a week behind.
I have kept the days of the main events up to date as revisions have come in though
If people are really interested ( and have fast Broadband) they can see the whole series day after day too by using the drop down list on the right hand column and selecting a month/year and then advancing page by page from there.
Heres my pages of the 3 main events so far
Sept3
Sept4
Feb21
Feb22
June13
June14

Last 7 days NZ
last 30 Days NZ
(both running 6 days old )
I think what makes Christchurch unique is the 10 month span of time, the population density and the small area the aftershocks are confined to.




Oh I just zoomed into the Feb 21st map and seen I did not revise that page as to the location of the 6.3 yet

hmm moore activity today....just an feeling....

The 'quake last night has been upped to a 5.4 and centred near Halswell (one of the Western Suburbs), Christchurch. It definitely felt like a reasonable shake last night, but we are more eastern and so weren't affected as badly, though it was a reasonably sleepless night. My Brother (Burnside) and Aunt (near the Airport) both lost power for around an hour.

Both Geonet and the Crowe site have revised this 'quake.

Right where the Greendale Fault ends and the Port Hills Fault starts eh?

Darfield (Greendale Sept 2010) Aftershock? or Lyttelton (Port Hills Feb 2011) Aftershock?

quite complicated.

In this case it was NZ; I keep my questions and remarks for Nabro elsewhere unless new big quakes.
Period is not much issue and the whole issue is not critical. Purely of interest. This might be a typical Pandora's Box.

What I would love to know at present is if we have the hungry stomach rumblings of magma audible. Most likely the best time slot would be for 1 to 10 minutes after a bigger quake under Littleton (extinct volcano) area.

Nope not yet, Those are just normal everyday tremmors in that region, some days one some days 30. What you should look for is when those lines on the graph goes upwards of 3.5 and the depth is less than 1 km.

Small quake of 3.2 in Gramby Quebec Canada at 06:07. 06-22-11

Two pretty large quakes, for this area...

6.7 in japan

reply to post by muzzy


My friends in Rolleston all feel that the "gap", as they call it, between the two faults is the next part to go - either that or the 2 5+s are it going in stages.

Did you see today's Ashburton Guardian article about the one over their way other night? Another unidentified fault on the Plainss... www.ashburtonguardian.co.nz...

Also note the wee swarm of quakes that the Lake Heron fault 4.8 has kicked off..

Interesting times!

No immediate reports of injuries or damage per AP:

Strong quake hits Japan; tsunami warning canceled TOKYO (AP) -- A magnitude-6.7 earthquake rattled northeast Japan early Thursday in the same area where a massive quake triggered a deadly tsunami in March, but there were no immediate reports of injuries or damage....

Interesting that it happened in the same area as the Tohoku Quake last March.

Looks like it was felt, from northern Japan through Tokyo, according to reports received by USGS. The greatest intensity was felt moderately in NE Japan, in Misawa:

As I write, a M 4.8 in Japan, off the shore near Iwaki: USGS

Folks in that beautiful part of NV and CA seem to be in some fairly risky territory.
USGS EQ Hazard Map

Berkeleygal, and anyone in CA...are you feeling more quakes out west than 'normal', (whatever that is, lol)? I've heard that so many of them are not felt at all. Completely subjective, I know..but am curious.

PDF Package for Mag 6.7 in Honshu, Japan now available. (2.5 Mb download)

Includes a copy of the initial Japan Met Office tsunami report

I am down computer-wise for data and anything to do with maps, graphs etc. Due to a set of circumstances beyond my control, not beyond my control and caused by but not limited to storms, power failures, programmer's stupidity but mainly Microsoft I do not have access to any of my data other than a raw copy. It is still being collected which is a relief!

It may be the weekend before it is up and running again. Head down working on it!

I don't know much about earthquakes so pardon my ignorant question..

Are all these very shallow earthquakes normal Puterman ??
