We were well prepared for disaster anyway, our Spa Pool sprung a seal on a knob a few days ago so we shut it down and waiting for a replacement seal from Auckland, so gave it a clean and refilled it with fresh water, no chemicals added yet, so 500+ litres at hand

Plus our usual 60 litres of emergency supply in containers.

I'm off to sleep hopefully, 2 coffees and 4 cigs to calm the nerves

I have changed the map on my El Hierro post (see signature) and it should work OK now. It is now specific to Google Maps.

Interesting stuff it one is interested in the technible bits, otherwise just go to sleep or let the eyes glaze.

I was aware that GM did not use the styles properly but it actually is worse than that. If you have a GM KMZ with more than one level of folder....

folder
inner folder
/inner folder
/folder

....the styles that supply the icon are not seen at all and you get paddles. If you only have one folder the first folder visibility turns everything off and the rest seems haphazard,

On the other hand if you do not use icon styles at all, and basically there is little of them used by Maps, the folder thing works OK.

Problem is if you run a Maps KMZ in Google Earth without styles every single placemark (way-point) is labelled and in a multiple earthquake list scenario that is worse than useless.

I am going to have to change the QVSData program yet again to create Google Maps only files, or Google Earth files. The main difference is that every line has to have a reference to the icon in Google Maps which makes the whole thing larger. On the other hand no label styles are required so a bit is saved there.

Puterman, I especially enjoyed the video on your El Hierro page, showing how the epicenters migrated west.
Well done.



Calling John Vidale, hello....... What is (not) going on with the PNSN tremor page?
It hasn't been updated since 29 June. Is the system experiencing difficulties again? I was trying to see if there was any tremor associated with this Mag 2.4 located just offshore Gold Beach.

Interactive 6+ NZ Historic Quakes Google Map centred on last nights quake

Interesting notes about Google (after that debacle of icons off centre a week ago) and Blogger, which is run by Google.
I wrote that NZ 6+ post in 2011 on Blogspot , before the Pegusus Bay 6.0, so that needed updating as well.
Then I tried to change the address of the post from tauhouanga.blogspot.co.nz/2012/05/1840-2011 to tauhouanga.blogspot.co.nz/2012/05/1840-2012 to keep it up to date. No can do, I'd have to delete that one and write a new one.
Also you can no longer set the date or alter the date the post is posted, which you previously could do, this was handy when doing historic posts to get them is sequence.
* Note to Puterman. I loaded that Mag6+ file that you kindly created for me when the icons were playing up.The icons were in the right place, and from memory the popup tags had the details inside.
When I added last nights quake to the CSV file it loaded fine on Google Earth, so I saved it under the same name. On Google Maps the icons were there, but there was nothing in the popup tags except "Address" and an "x". I renamed the KML file and sent that through Dropbox rewrote the i- frame html etc and all is good now.

Google are really making it hard to like using Blogger!, I think I'll transfer all my Blogger pages over to Wordpress.
I wish someone else would get into mapping, and offer the i-frame creation option, Yahoo do some stuff but when you use Yahoo the map comes up in Google anyway.
I had a go at OpenStreetMap.org a few months ago, where you have to register, it seemed to me that was more for map development than day to day use.

Yep I see July2 now.

Yep Google Maps seems to only use one size icon, 32x32pixels, so styles in the KML make no difference.
Making smaller icons won't work, they still come out 32x32 and come out blurred. See how your smaller Aqua icons are not as sharp as the Orange ones.
Yep to get the list on the left hand column you have to give each item/marker a label/ name.
Real PITA

If that was the case all the SNZO seismograms would be trashed but they are not as you demonstrated.

All of the 00 location plots are screwed, BHZ, LHZ and VHZ but the 10 locations are OK.

re above post

Actually they are all the same size 64 x 64




I need to look into scaling in maps further it would seem.

I made some smaller orbs inside a 32x32 clear background canvas and thought that would solve the issue, but they still came out the same size on GMaps. In the end I gave up trying, and all my icons are 32x32 now.
How did you get them Aqua ones smaller then? did you write something in the KML to force GMaps to recognise the style?

Here is an odd little swarm of quakes just north Half Moon Bay, CA. I've never seen one in this location before.


source
It looks to be on a fault parallel to the San Andreas, and about 10 km west.
The depths are averaging near 8.5 km and the magnitudes are small--nothing larger than 2.8.
Just letting off a little stress, I guess.

yeah I know its the S-wave, but still why no Mw reading from USGS? should be 5.27Mw at least by using the Geofon calculation method for USGS.
keeping the numbers down on the moderate sized quakes count too?

Totally off topic but I hope the Mods will forgive.

Happy Independence Day



Watch out for the UFOs. Quite why anyone would wish for independence from the Crown I cannot imagine


 

El hierro had fewer quakes each day over the last three days. Some are cherry picking the bad sections and showing the seismos - for example this for early today

Today 00hrs to 01hrs

Whereas the full day at 0700 UTC has no further activity.

This image will change over the day.

Mystery disappearance of Sumatran earthquakes



USGS were being questioned today by detectives from the Earthquake Protection Squad about the curious disappearance of two Magnitude 6 earthquakes. Last seen on or about the 12th April, 2012 it appears that a person or persons unknown have removed these quakes. Despite continuous waterboarding for several hours the database would not yield any information.


usgs 11/04/2012 14:32 6.1 Off W. Coast Of Northern Sumatra
usgs 11/04/2012 14:40 6 Off W. Coast Of Northern Sumatra


Cross checking with other information sources reveals that these two quakes, known by the USGS as 2012zgmw and 2012zgmn have either been removed from other lists or may never have existed.

These two quakes were not in the original listing but were added after the event. Seems it may have been in error. This reduces the year total of Mag 6 to 64.

 

And another one, and another one, and another one bites the dust


usgs 11/04/2012 14:46 6 Offshore Taitung City. Taiwan


They must have been having a bad quake day on the 11th April!

2012zgm1

And then there were 63!

Funny man! And thank you. Reading your most recent post below, you're on a comedic roll today, PM.


I justed looked on the USGS Errata page, I didn't find your missing Sumatra quakes, but the 'short-lived' offshore northern CA mag 5.9 from the same day (2012/04/11) is listed.

Maybe this latest missing duo will be added to this page shortly?

Abstract

The scarcity of long geological records of major earthquakes, on different types of faults, makes testing hypotheses of regular versus random or clustered earthquake recurrence behavior difficult. We provide a fault-proximal major earthquake record spanning 8000 years on the strike-slip Alpine Fault in New Zealand. Cyclic stratigraphy at Hokuri Creek suggests that the fault ruptured to the surface 24 times, and event ages yield a 0.33 coefficient of variation in recurrence interval. We associate this near-regular earthquake recurrence with a geometrically simple strike-slip fault, with high slip rate, accommodating a high proportion of plate boundary motion that works in isolation from other faults. We propose that it is valid to apply time-dependent earthquake recurrence models for seismic hazard estimation to similar faults worldwide.

8000-year quake record improves understanding of Alpine Fault
June 28, 2012

phys.org/news/2012-06-year-quake-alpine-fault.html

(...)

The investigation found the mean interval between large earthquakes on the fault is 330 years and two thirds of the intervals were between 260 and 400 years. As with many natural systems, there was a spread of intervals with the longest being about 510 years and the shortest about 140 years.

The Alpine Fault extends about 600km along the spine of the South Island between Milford Sound and Marlborough. When it ruptures, it produces an earthquake of about magnitude 8.0.

(...)

Based on this research, scientists have estimated there is a 30% probability of a large earthquake on the Alpine Fault in the next 50 years. This is at the higher end of existing estimates, which were based on only the last four large quakes on the fault. Scientists have more confidence in this new estimate as it is based on a much longer earthquake record.

(...)

For project co-leader Ursula Cochran, also of GNS Science, the long earthquake record they uncovered highlighted the inevitability of a major earthquake occurring on the southern section of the Alpine Fault in the future.

“The last earthquake occurred about 295 years ago, so there is no better time than the present to prepare for the next one,” Dr Cochran said.

At the household level, these measures include emergency kits, anchoring furniture, removal of old-style chimneys, and family communication plans. At the local community level, measures could include planning for the care of the elderly and young if the community is isolated, and identifying skills and equipment helpful in a disaster.

30% chance of 8 quake
By Laura Mills

www.greystar.co.nz/content/30-chance-8-quake

(...)

Auckland University professor of biostatistics Thomas Lumley said that using the numbers in the paper, “I get 32% chance at 50 years, and 50% chance at about 80 years”.
“The risks are high, but that’s because it seems to be an unusually regular fault.”
Long earthquake records have been obtained from only about four other faults around the world, including the San Andreas Fault, in California. The latest findings underpin an idea over 100 years old — that some faults might rupture regularly, rather than at
random or in clusters.
Other faults that have similar characteristics to the Alpine Fault include sections of the North Anatolian Fault, in Turkey, and the Denali Fault, in Alaska.

Chile - June 2012
- 338 earthquakes on this interactive map

Due to the narrowness of Chile I was able to put 2 maps side by side, so made a 4+ map as well.
EQArchives

Greece and Turkey now have maps showing "all" and "3+" quakes for June and July (Turkey and Greece tabs at top of the page I linked to above)

I've started converting Utsu's historic data to maps for each country as well (click on "Utsu" tab),
thought it would be OK on this blog, rather than interfering with MWE7+, as I am lifting 6+ data.

5.1 quake shakes Anguilla; no damages reported

hosted.ap.org/dynamic/stories/C/CB_ANGUILLA_EARTHQUAKE?SITE=AP

THE VALLEY, Anguilla (AP) -- An earthquake has shaken the tiny Caribbean island of Anguilla. There are no reports of injuries or damage.

The U.S. Geological Survey reports the quake's preliminary magnitude as 5.1 and says the epicenter was about 6 miles (10 kilometers) east-southeast of Anguilla's capital, The Valley. But it says the quake occurred far below the surface, about 55 miles (88 kilometers) down - a depth that tends to lessen the power of a tremor's shaking.

Police constable Terry Sylvester tells The Associated Press that it was the strongest earthquake he has ever felt but says residents have not reported any damage.
