Quake Watch 2013

Here is a link for the NCGT Newsletter for December 2012 (Seems the link they provided in the email I get is bad. Go to the site and download from that page.

Solar activity linked to high-magnitude earthquakes, Stephen A. REYNOLDS
  Magnetometer data from GOES for 2001 to 2011 were assessed against 7.0-plus magnitude earthquakes worldwide. Results showed these earthquakes clustered towards strong solar activity. The statistical correlation was then validated against a hypothesis, that fault lines were fed increased electrical energy in a similar way to geomagnetic-induced current.

9/56 year cycle: 18th & 19th century world earthquakes, David McMINN
  The 9/56 cycle was assessed in the timing of major 18th and 19th century world earthquakes. Remarkably, most 1765-1885 seismic events (M => 7.9) took place in one half of the complete 9/56 year grid. Since 1900, world mega quakes (M => 8.5) also occurred preferentially in 54/56 year grids, something that was considered in relation to earlier centuries.

Can IMF and the electromagnetic coupling between the Sun and the Earth cause potentially destructive earthquakes? Valentino STRASER
  Trends in the Interplanetary Magnetic Field (IMF), detected by GOES satellites 13 and 15, show some recurrences in the graph, as a characteristic "σ" shaped hook that is detected before earthquakes of magnitude M6+. Due to the recurrence of the event, in the form of "σ", almost always present before strong earthquakes, the method aims to provide a contribution to the interdisciplinary study of seismic precursors of a global character.

Intervals of pulsation of diminishing periods and radio anomalies found before the occurrence of M6+ earthquakes, Valentino STRASER
  From spectral analysis of more than 350 earthquakes, it was noted that the micro pulsations and the radio interference detected, respectively, at a value of 665 mHz and in the range between 0.1 and 20Hz, precede by a few hours the occurrence of M6+ earthquakes.

The Raffaele Bendandi earthquake warnings based on planetary positions, Cristiano FIDANI
  Raffaele Bendandi was well known during the first half of the twentieth century for his warnings on the onset of earthquakes which were made in newspapers worldwide.

Essays
  Earthquake and volcano “predictability vs crustal diagnosis”, Giovanni P. GREGORI
  The Tethys configuration and principal tectonic features of the Middle East: a wrench tectonic survey, Karsten STORETVEDT and Soheila BOUZARI

Geopolitical Corner
  Bad vibrations: Lessons from l’Aquila, Michael KILE

Publications
  The tsunami threat, Nils-Axel MÖRNER

Most of these are items in which I have a strong interest, but be warned, do NOT take any of what is said for granted. Despite what some of these types of article say there is not yet any repeatable statistical evidence that I can see and you need to watch for careful manipulations designed to 'bend' the data towards the desired result.

Maybe I am just an auld cynic but I want to see repeatable verifiable data fits that match at least 85% of the cases before I will accept that an hypothesis has merit.

Despite the foregoing it is interesting stuff.

no one in a couple of months wants to read a forum that is full of dead links eh

Unfortunately, unless the earthquake is a significant one in the eyes of the USGS those links will vanish in 30 days as well.

Only GFZ Potsdam and EMSC retain their links forever as far as I am aware.

ETA: EMSC also retains the data it has received from the USGS so for Mag 5+ quakes it is a complete repository.

Nice work and thanks for the caveats. There may well be something in common that underlies these correlations that we have yet to understand. It would be interesting to check if EQ activity suffered a minimum during Solar Minimums such as the Marauder(?sp) Minimum.

Nice find, my thanks as always.

Another thought on correlations.

I think 85% is too high to aim for. Let's try an analogy. I have a house full of light globes that sometimes stop working. Let us assume that over the course of a year they all need to be replaced. I want to find out why they stop working.

So I do some research. I find that some stop working after a brownout, some stop working after a voltage spike, some after an electrical storm and some stop working for no apparent reason other than age. If I go for a correlation greater than 85%, I will never get an answer. If I assume though that as they age, globes are more susceptible to brownouts, voltage spikes and lightening then I start to realize what the overall problem is.

I think that for an EQ to occur, the plates must be under stress in the first place. Then I can assume that various Solar events may trigger an EQ, ie the straw on the camel's back. If such an event does not happen then the EQ will happen anyway at some point in time. There may be many different triggers for EQs. The events caused by Solar events are just one of these.

Therefore, an 85% correlation could be too high. Just food for thought.

What's withthe USGS site this morning. Has Y2K hit 13 years late?

Note the dates...

That is bizarre and hilarious And try as I might, I cannot replicate that date error myself. I'm a little jealous you got to see that. Kudos on bringing the weird to us today

The USGS page is a mess. No colours and the dates are wrong. I think the locations may be correct. I liked the old one. sigh... (edit... they've fixed it and added the Okie frackquake)

During the Thanksgiving holidays I noticed that the frackquakes in Oklahoma slowed and almost stopped. The pattern has been the same over the Christmas break. Now that the holidays are over, the earthquakes are back with a dozen or so yesterday. I'd list them but it's a pain. Then you get a bigger one this morning 3.5+M. They must be back to normal operations. So, when you notice the next bigger one, it may be much bigger.

www.okgeosurvey1.gov...

I want to write to that Oklahoma geologist who said the drilling has nothing to do with the activity because it's all normal. I want to ask him about the correlation between holidays and the earthquakes. I noticed the same thing in Arkansas the year before with the holidays, and that's what convinced me. Earthquakes don't care what day of the week it is or day on the calender. When they do, it's not the sun, moon, stars or planets, it's man, and woman kind.

I saw a really annoying reporter asking a geologist about all this fracking. Ug. too outraged to write much. The same company that brings you the news about the frackquakes and the water pollution are the same companies that sell ad time to the drillers and they are the same company the sells air time to the government that's make the "pitch"-prop.
The TV folks win no matter what. What would they work to solve a problem that makes them so much money. Better to have all sides buying time during all that contraversory. I am scream. I am mad. And I don't mean the angry mad. I have gone quite mad and now am begining not to care. I ask myself, why the frack do you care about this robin? whay can't you stop looking?

I guess I lke horror movies and I gawk at acr wrecks. I guess I'm no different.

Ha ha ha. What a stupid question. And we are fat and stupid. What's news about that?

www.cbc.ca...

One last thing. I have been wondering why haven't we had a bigger quake in the eastern U.S. and etc. Well, I think the drought along the Mississippi has lots to do with the quiet. They are trying to dredge near St. Louis and this means the southern half of the Great River is low. And coincidently, so is the earthquake activity.

Are all these 4 magers(new word ) migrating down toward the big junction S. and E. of Tokyo??

Lots of cross posting! sorry.

GFZ Potsdam have it as 7.4

geofon.gfz-potsdam.de...

I guess this is Post Traumatic Stress Syndrome from the Queen Charlotte quake

Crap, that is the one I have been waiting for. That could be the top end of the plate starting it's rebound. God, I hope it is not.

It is not the top end of the plate rebounding. This has nothing to do with the subduction zone and is related to the stress release from the BC 7.7

There will probably be further M6 quakes either side of this one over the next few days/weeks.

Here is the first of the aftershocks
