Quake Watch 2011

reply to post by PuterMan

I'm doing it manually so seeing the Date/Time as the main difference between multiple entries.
And once they are loaded to a csv file and sent to GE I can see where they are clustered.

If by "multiple version listings" you mean show them all then I think thats a safe bet, let people draw their own conclusions.
I like the way my text file for the Global 5's came out, you can clearly see which quakes match (90% of the time) and I've seperated them for clarity.
eg. text file

On another note, Im having a few issues with the USGS data, I'm taking the data off their Latest Quakes Worldwide-Last 7 Days page rather than using NEIC which is usually a day old, and when I convert to csv the dates and lat long have tabs either side that mess up the main list when I load it to Excel, all the other sites have similar parameters and don't cause any problems. I've tried putting the USGS data through Notepad and Word, but the only way to fix it seems to be to delete the tabs manually.
Any ideas?

I assume you've tried the REPLACE feature in MS Word?

Highlighting the body of text within which to do the replace and then . . .

Say replacing a tab with a"|" [verticle line above backslash on my keyboard]

Or maybe with an "_" [underscore]

or even with a space?

Sometimes the replace function can be real funky to troublesome.

I wonder, if the above doesn't work, if you could first use the REPLACE function to

ADD say an "*" astrisk to each side of the tab as a first step.

Then replace the whole

*TAB*

with whatever character you preferred.

Very easily solved. Use the Mag 5 CSV file they provide.

You can find it on this page, or use the direct link

Yup 1 pixel out is just intolerable.

By the way are you aware that you can re-snag using Ctrl+Shift+R

This is very useful. What I do is create a set of data as a KML and load it into GE. Then using the tick boxes turn off the days I don't need and snagit. Turn off that day and turn on the next and Ctrl+Shift+R. This means your capture is in EXACTLY the same place provided you have not moved the screen. Much easier than trying to match the precise position and size.

0 km deep? Is that a measurement error or how does that actually work? Cracks in the surface?

I don't remember seeing very many quakes here before. I may have never noticed either.

Another 3.6 in Nevada too

It's not very active in that area, for sure...

Yes I have done that, in fact I use Replace a lot, in Notepad and Excel as well as Word to create my lists.
It just seems a lot of fiddling around when doing USGS, for one thing the tabs each side of the latitude and Longitude are different widths.
It has to be something to do with the format they are presenting on that page.

OMG it ewas there all the time
Thanks I forgot to look at that page, I often used their KML when I was learning how it worked.

reply to post by PuterMan


excellent tip, I'll try that out.
Snagit is way better than the MS Snipping Tool I was using before.
I just learned you could load your own Stamps (the opaque bubbles around the japan quakes on the map a few pages ago).

I'm going to try and load up the all the Networks data tonight for 21st through 27th, got all the data up to 26th already except JMA
Letter ID, Network, Abbreviation, Magnitude Type
E = European-Mediterranean Seismological Centre, (emsc), Mw Moment and mb Body Wave
G = German Research Centre for Geosciences, (gfz), M Composite
R = Geological Survey Russian Academy of Sciences, (gsras), mb Body Wave
U = United States Geological Survey, (usgs), Mw Moment and mb Body Wave
B = Badan Meteorologi, Klimatologi dan Geofisika Indonesia, (bmkg), ML Richter
C = Geofísica Universidad de Chile, (guc), ML Richter
N = Institute of Geological and Nuclear Sciences New Zealand, (geonet), ML Richter
A = Geoscience Australia, (ga), Mw Moment and mb Body Wave[

I have not checked this out folks as I am rather busy at present but someone might like to take a look. This was sent to me in and email so I can't give a link to the source.

9/56 YEAR CYCLE: CALIFORNIAN EARTHQUAKES

David McMINN
Independent cycle researcher
Twin Palms, Blue Knob, NSW 2480, Australia


Abstract: This paper examines the prospect of a 9/56 year cycle in the timing of major earthquakes in California - Nevada - Baja California. These important events tended to cluster within this grid, far more than could be expected by chance. Hawaiian quakes were also assessed and showed similarities with seismic episodes in south western North America. Furthermore, record seismic quakes appeared selectively within the 9/56 year cycle and included such key historical events as the 1700 Great Cascadia quake, the 1906 San Francisco quake and the 1980 Mt St Helens eruption, as well as the record quakes for Nevada, New Mexico, Arizona and Hawaii. Seasonality was another crucial factor as seismic events tended to occur around the same months of the year within various 9/56 configurations.
The 9/56 year seismic cycle was hypothesised to arise from tidal triggering by the Moon and Sun. What seemed most significant were the ecliptical positions of the Sun, lunar ascending node and apogee. This implied that the angles between these factors and the spring equinox point may offer clues as to how this cycle actually functions. The siting of the Moon on the ecliptical circle should also have relevance, although no supportive evidence could be offered in the paper.

Key words: earthquake, cycle, 56 year, California, Nevada

It has long been my contention that most of these things come in cycles so this is an interesting statement. I will take a look at it later - probably many days later - and see if I can find the paper.

There is email address for this person so if you feel a need to email him please u2u me and I will give you the address.

There is another interesting item in the email which I am posting in the Geophysics thread.

Looks interesting, but not up to reading it tonight. You've probably got the necessary data to validate or debunk this theory.

NZ very quiet for the last 7 hours.

Only 3 quakes listed last 24 hours

Time vs Mag Graph

Big One Coming

Maybe not, the Drums are pretty quiet overall, but the very sensitive ones, Mangatainoka River and McQueens Valley are showing some events, so it could just be a processing issue at HQ.

I think that it is like I have been saying. After a superquake the world seems to go quiet for a while - as much as a year.

I am going to have to set to and prove this theory!

We're still shaking in Christchurch. Though it is a tad unsettling that yesterday was very quiet. Still on edge, and every shake brings that little adrenalin rush.

Good to be back at work though.



Soon there is going to be seismic data on the 'crossover' between the Greendale and the Port Hills Fault. They've already completed the 'City' sections:

Seismic ChCh

Gravity Survey as well

University link

Apparently they have recognised some structures from the initial (raw) data, but it will take months before we get any solid processed data...it was difficult at times because of the traffic, but they got there. also, the depth of penetration is not as great as it would be with an explosive seismic source, but that is a tricky task in a populated area. It was difficult enough in the countryside!

I'll keep you posted if I hear more.

reply to post by PuterMan

Yeah OK go ahead if you have time. I hadn't noticed a downturn here in NZ since japan 9,0, in fact we have been getting a Mag 5 about once a week, and 4's every day (not just Christchuch either) which seems more than normal..

reply to post by aorAki


good to hear from you.
So its going to be called "The Port Hills Fault " eh, geez thats imaginative
Seen that Tractor on TV, it lets out a good vibration by the look of it, enough to make your teeth chatter ?

Rolleston seems a good place to start, during the Darfield aftershock sequence ( before Lyttelton 6.3) it was probably the most mentioned placename in the lists on a daily basis.

Just downloaded the data again from Geonet,
Still just 3 quakes with magnitudes for the 27th, so it was a quiet day after all.

10 quakes for the 28th, incl. a 4.15ML SE of Whakamaru, Waikato, so somewhat back to "normal"

Your link does not work and there is no information i the source code of the page to be able to work out what it was.

I found this article and was wondering if this was what you were linking to?

sorry, no idea why the link I pasted didn't work, and I am even more sorry for taking so long to reply to your query, but I have so many other things to attend to that sometimes I forget some of the other things what I am busy with. I guess I had some finger trouble when I posted it (quite normal for me), but yes, your link points to the same as the link I thought I pasted, but here is the actual article I wanted to refer to. (Hopefully I do it right this time)
