Thats a really good question but I have no idea....would like to know myself.

I found this site although I am not sure of the accuracy. Check it out. www.ceri.memphis.edu...

lol...that was the first site i went to when i started my query. interesting...but it still didn't answer my question. thanks for the response though. star to you!

Seems a bit odd to me.

Historic seismicity shows that it's not alone and that since 1990 there've been a few quakes in the area.

That question is near impossible to answer.
What Network?
If you tried to combine all the Worlds Networks results you could probably get 3000 times what USGS show on any given day.
Its not numbers that count anyway, its size and energy released.

My best guess would be any day after a Mag7, 8 or 9 on land, you could start there, try 2004 Dec 27 (Sumatra) or 2011 March 12 Honshu), 2011 October 24 (Turkey) you get the drift

heres your best tool www.ncedc.org...

I know this thread is really about quakes but we find more and more how interlinked they are and Dutch Sinse here puts out a warning with this recent Japanese Volcano which has been naughty for about a year now but appears to be gearing up for showing off.

South of Fiji mentioned a page back

had a look at USGS and GEOFON, quite a difference, matches based on the time of the event


MATCHED 5
USGS missed 7
GEOFON missed 3

Of interest to me because they all show on LISS SNZO, just using USGS to ID the traces would have been very frustrating!

I got the USGS data off Latest Earthquakes

These quakes are near the submarine volcano known as Volcano 19 which is actually closer to Tonga than Fiji, but Geofon (and USGS Latest Earthquakes in the World - Past 7 days) use the F_E region name South of Fiji Islands FE=171.

Submarine volcano
Calderas
Cones
Summit Elev: -385 m
Latitude: 24.80°S
Longitude: 177.02°W
A large submarine volcano located at the southern end of the Tonga arc rises to within 385 m of the sea surface. Known informally as Volcano 19, the basaltic to basaltic-andesite seamount contains two calderas, a 3.5 x 2.5 km wide outer caldera and a 1.9-km-wide inner caldera on the west side of the volcano. A central cone complex lies in the center of the outer caldera, east of the inner caldera. Two large hydrothermal fields are located near the summit of the central cone complex and at the base of the southern wall of the western inner caldera. Large high-temperature chimney vents discharge clear fluids and black smoke.

I thought it was March 22 based on some planetary alignment or something. Here is the usual You Tube junk about it.



and



There is also an entry for another conspiracy site that we don't mention where it has been confirmed ( ) that there will be a major earthquake on the 22nd March.

I believe some of the reasoning is that the alignment is similar to that which occured on Mrach 11, 2011 so they say which may be where the 11th comes in.

Needless to say some of this is built on the 188 day theory which is completely discredited.

There may be a major earthquake on March 22md, but if there is it will have no connection to the ramblings of various You Tube seers and prophets of doom.It will just be pure fortuitous (for them) coincidence.

Interesting question but I am afraid one that is virtually impossible to answer!

What magnitude do you count for example? There are literally probably thousands of very very small earthquakes that go undetected worldwide daily.

This page from USGS on quake stats (which are probably low ) give us 3957 quakes daily if you add up the figues and divide by 365. But that is only Mag 2+. Since there are numerous quakes below that daily down as low as Mag -3.0 the figure is probably tens of thousands a day.

Yes this really should be in the Volcano Watch thread - there is a link in my signature for future reference.

This is not a recent volcano, it has been erupting since 1955 and not only is it considered to be continuously erupting, it was also designated one of the 'Decade Volcanoes'

A rather garish site about Sakurajima

and last my page on Japan with some more links.

As far as I am concerned (and here I reserve the right to be pompous) Dutchsinse is NOT a credible source of any information although I will concede that he is getting slightly better recently - probably since his run in with USGS when he got his fingers burnt.

Not so fast my friend. Whilst I accept that USGS are not the best, you may be doing them down.

It just might be that Geofon is way too hasty and publishes without fully checking. You will find that some of the 'missing' ones are creeping on to the list (Never did like that new interactive thing), including some that Geofon seem to have missed.

I don't have time to check them all but here are some

Now on USGS

earthquake.usgs.gov...

On USGS but not in the list
earthquake.usgs.gov...

Until about a month or more has passed you cannot consider the listings anywhere near final, and as the PDE says it can be up to 2 years before being considered final.

Whilst I collect the data from USGS, my reports are based on ANSS after 1 month has passed.

My take over of the limelight is finished with this one. I thought you might like this statement in the Potsdam Manual.

Despite the tremendous progress made since Wiechert in understanding the most prominent features in seismic records, long-period ones in particular, we are still well short of reaching the goal he set. In fact, most operators and analysts at seismological observatories, even those who work with the most modern equipment, have not advanced much beyond the mid 20th century with respect to their capability to "understand each wiggle" in a seismic record.

Source: Aim and Scope of the IASPEI New Manual of Seismological Observatory Practice (NMSOP) by Peter Bormann Comment is on page 4 of History of the manual 1.1 (Page 35 of the Scridb document)

The good news is that these are the people we rely on to keep us safe!!

What a good job we have our team of 'experts' here as well!!

Indeed, I thought that USGS Map/List combination would be/was handy to zoom in to an area and get swarms/clusters of quake lists without having to copy and paste the text off 7 days and sort it out by lines. So it seems its not very accurate at all, with some quakes missing, I see its changed from the Beta version, but seems it still has theething problems, not matching up with the 7 days list. Back to the drawing board

Well thats reassuring (not)
That looks like an interesting document, 1253 pages ,

This section caught my eye (page 38 on the scribd link)

1.2.2.1 The magnitude issue
Earthquake magnitude is one of the most widely used parameters in seismological practice,and one that is particularly subject to misunderstanding, even by seismologists. Examples of the way in which changing operational procedures have contaminated a valuable data set haverecently been put forward and discussed in the Seismological Research Letters. After re-examining the earthquake catalogue for southern California between 1932 and 1990, Huttonand Jones (1993) concluded:
•
ML magnitudes (in the following termed Ml with l for “local”) had not been consistently determined over that period;
•
amplitudes of ground velocities recorded on Wood-Anderson instruments and thus Ml were systematically overestimated prior to 1944 compared to present reading procedures;
•
in addition, changes from human to computerized estimation of Ml led to slightly lower magnitude estimates after 1975;
•
these changes contributed to an apparently higher rate of seismicity in the 1930’sand 1940’s and a later decrease in seismicity rate which has been interpreted as being related to the subsequent 1952 Kern County (Mw = 7.5) earthquake;
•
variations in the rate of seismic activity have often been related to precursory activity prior to major earthquakes and therefore been considered suitable for earthquake prediction;
•
the re-determination of ML in the catalogue for southern California, however, does not confirm any changes in seismicity rate above the level of 90% significance for the time interval considered.Similar experiences with other local and global catalogues led Habermann (1995) to state: "...the heterogeneity of these catalogues makes characterizing the long-term behavior of seismic regions extremely difficult and interpreting time-dependent changes in those regions hazardous at best. ... Several proposed precursory seismicity behaviors (activation and quiescence) can be caused by simple errors in the catalogues used to identify them. ... Such mistakes have the potential to undermine the relationship between the seismologicalcommunity and the public we serve. They are, therefore, a serious threat to the well-being of our community."

*emphasis mine

So we are not the only ones who struggle with this issue

I started analysing the LISS SNZO graphs because I use it as my Home page and its the first thing I see on my computer each time I open Firefox, IE or Chrome, over time I'm getting to recognize where and how big each trace is, and there always seems to be the odd one or two that none of the networks were able to pin down.
Up to this point I haven't bothered going back later and checking to see if they did find where the trace came from and how big the quake was, perhaps thats another task I need to include in my rainy days schedule




from that page

variations in the rate of seismic activity have often been related to precursory activity prior to major earthquakes and therefore been considered suitable for earthquake prediction;

This is something I thought I observed here in New Zealand, up until the end of 2011. However on closer analysis it seems to be a Red Herriing, By collecting the data over a period of several years and converting to into graphs I found that while seismicity did drop off a few days prior to a Mag 5+, it was a random thing, and didn't happen every 5+, plus the data was incomplete and only based on Preliminary Data downloaded within a few days. Looking at the revised and updated data from Geonet 2-3-6 months later, it turns out the drop off ( eg to just 2-5 quakes or even

I've tried to locate the satellite image you posted, but to no avail - The Texas panhandle, it turns out, is pretty large. You mind giving me a little clue as to what it is, or have you already done so, and I'm simply a little obtuse today? If I were to hazard a guess, I'd say it's some sort of weapons storage area. Would I be even remotely close?

BTW, Just wanted to say that I thoroughly enjoy and appreciate your posts...

The image was taken from above right of the epicentre of the earthquake there. Specifically 7 miles on a bearing of 320°

The white rectangles connected by roads are without doubt existing/old oil/gas pads. The whole area is littered with them.
