In the last quake thread I’d said:
Well, Vanuatu Rocking isn’t all THAT odd, but they did get a 7ish scale event, and that matters. Then Colorado popped a modest one (that isn’t notable other than where it is, really), but now the East Coast has a large quake? At that point, the memories of the New Madrid quake have to start being dusted off.
But now we have ANOTHER 7.x in Vanuatu. “Watson, the game is afoot!”… Don’t know what it means, other than that Vanuatu is an exciting place to live these days, but 2 of about the same size and time leads me to wonder “Who is a foreshock of whom?” and what is to come.

Some Volcano Stuff
This page:
http://pangea.stanford.edu/~dsinnett/Pages/Links.html has a nice collection of links to volcano monitor pages. Just click the pictures for the different volcano observatories.
The Smithsonian page:
EM,
We’ve discussed the relative lack of an association between the suncycle, volcanoes, and earthquakes. Plus maybe a few other possible variables. However, there appears to be some increase of volcanic activity in the ring of fire that’s coincident with a consistent earthquake activity. Maybe it is just better reporting and accessibility to data. But I wonder if that japanese big one is associated with continued shifting? Tambora appears to be rumbling a bit. that would not be good.
http://www.emsc-csem.org/Earthquake/Testimonies/comments.php?id=234523
The USGS site only shows larger quakes. this site shows activity increasing near the german-Czeck border. Funny that.
Here’s a good link showing increased activity and alert raised or ongoing at 22 volcanoes in Indonesia, etc, .
http://www.thejakartapost.com/news/2011/09/03/increased-activity-22-volcanoes-alert-raised.html
@ Tim Clark
The quake swarm at Czech-German border (I posted about the first swarm last week) has happened before.
This article about the swarm links the activation of a fault to be possibly related with rising magma. The area is covered by old volcano’s that were regarded to be extinct.
http://theextinctionprotocol.wordpress.com/2011/08/27/earthquake-swarm-reported-on-german-czech-border/
Interestingly enough similar quakes and small swarms occur in the volcanic are around Koblenz in Germany.
Very interesting stuff that tells us Western Europe is not the safe and quiet place people thought it was.
Insurance companies will be pleased to sell quake insurances where they sold none over the past decades.
As for Mount Tambora,
I’m absolutely not worried about Tambora as it had already three VEI 0-2 eruptions after the big bang of 1815. It will take many, many years before another big bang is pending which won’t happen in our lifetime.
http://bigthink.com/ideas/39980
As for the quake, volcano, sun connection, there is a statistical relationship between the frequency and strength of quakes, volcanic eruptions and (low) solar magnetic activity of our sun.

And harmonic tremor

@Tim Clark:
Please make it clear, that’s QUAKE activity increasing at the German / Czech border!! ;-)
It is a strange place to be shaking, though…
@R. de Haan:
Why do I get this feeling that something big, hot, and bad is going to happen in Europe…
That, and the stock market is having a bit of a melt down on political changes to the market rules…
Somehow I think I’m rather happier to be in Florida right now than down wind of Iceland and on top of a German pressure cooker…
Of either / any kinds…
Not liking big sized quakes in Sumatra either…

Most likely water is causing harmonic tremor in Katla volcano
http://www.jonfr.com/volcano/?p=1449
Quakes continue
Knowing nothing about quakes, what do the 20+ quakes around Tom’s place at Mammoth with “shallow depth (~1.2km), poorly constrained” signify, magma movement or tectonic?
Remarkable
Just been hit by a 4.3 quake with the epicenter approx. 30 km from my house near the town of Cuyk (Netherlands) on the other side of the border.
The event was very short but it really made the house produce some mighty cracking sounds.
This is the second time I have experienced a quake in this region.
The first was in 1992 near the town of Roermond.

Katla Volcano
@Tim Clark:
That’s the $64 Billion question… Sometimes it’s either. But any time there is a quake storm around a major volcano, you start watching for ‘harmonic tremor’ to tell you if the magma is getting to the surface. At a place like Mammoth, that can be horrific…
@R. de Haan:
Let us know if you get a volcano ;-)
Are the folks in Netherlands spooked by the quakes?
@All:
Frankly, the Indonesia cluster has me more worried than most of the rest. It “has history”…
And I note in passing that the area around Japan continues to have a LOT of modest sized quakes. Looks like the whole northern edge of the Pacific Plate is in motion (and some of the south western edge too….)
It looks like that 6.8 quake up in the Aleutians might have caused the magma to start flowing again into Mt. Cleveland’s magma chamber:
http://www.alaska-native-news.com/article/Rural_News/Rural_News/Mount_Cleveland_Volcano_Continues_Building_Massive_Dome/23229
@E. M Smith
Many people called the emergency services.
But we have to keep in mind that quakes are very rare in this part of Europe and the area is one of the most populated area’s in the world.
Strange enough there is no consensus about the exact location of the epicenter of this quake, it’s strength and depth.
Some agencies report the epicenter in the Netherlands, others near Xanten or Kleve in Germany .
Strength reports vary from a 4.2 to a 4.6 and depth varies from 14 to 7 km.
http://earthquake-report.com/2011/09/08/moderate-shallow-earthquake-with-epicenter-in-germany/
It could be that this quake is related to shale gas drilling activity.
This is a developing story and I will report any outcome.
This site has a simplified picture showing what harmonic tremors look like relative to the other types.
Now, if I could only find an actual seismograph of one of those ML quakes.
Cascadia Calling at 6.4 –

Just for the record: Tamborra
From john Seach’s blog:
Friday 9th September 2011
Tambora Volcano, Indonesia
Tambora volcano in Indonesia has been raised to level 3 alert (out of maximum 4) on 8th September. On 6-7 September continuous tremor was recorded at the volcano. On 7th September there were 40 shallow volcanic earthquakes. A 3-km exclusion zone has been placed around the volcano.
Burst of heavy rain in Silicon Valley …
Earthquake swarm at Katla…
http://www.jonfr.com/volcano/
Well….
So we’ve got Katla rattling things (watch out Europe…) and we’ve got Tambora clearing it’s throat (watch out world) and we’ve got The Cascadia doing some pre-quake warm ups, and we’ve got a very nicely defined line of quakes along the inner zone of weakness of California (Hayward / Calaveras system) that usually lets loose a couple of years one way or the other from the San Andreas (that had a big one a couple of decades back) and sometimes let loose just after The Cascadia…
All we need now is for the swamlette around Mamouth Mountain / Lakes to turn into something like 5.x sized events …
E. M. Smith
So far I think it is correct to state that we have been a bunch of lucky bastards to be alive in a relative stable and warm period in time with great technology and high living standards.
Despite the recent natural disasters our planet is a great place to live.
Many people however lack any appreciation and some hard core zealots spend their entire life time telling us how bad it is.
Can’t wait for the technology to beam them into an ice age.
Here’s a Canadian site showing the smaller earthquakes in British Colombia.
http://earthquakescanada.nrcan.gc.ca/index-eng.php?tpl_region=swbc
Also some curious quakes in Texas and Oklahoma. 4.4 in Texas yesterday or the day before followed by 6 or more ~3.0 aftershocks, and at some point there was also a 3.3 in Oklahoma.
_Michael
Ok, add a 3.0 in alabama. Sheesh, how bizzare!
BTW my other earthquake info (other than our gracious host) is youtube.com/user/solarwatcher
Apparently he believes strongly in solar influences on earthquakes, specifically through interaction with the magnetosphere – and currently we’ve been in about a 2 day long geo-magnetic storm (off and on, but it seems like a fairly unsusual, sustained event).
Maybe a connection with these central U.S. 3+ scale quakes.
_Michael
Earthquake in Alabama a few minutes ago!
Pierce Corbyn makes his long range weather forecasts on a similar basis and just won a BBC price for the best long term summer forecast for the UK
http://climaterealists.com/?id=8334
Michael, where do you live? Texas perchance?
And now an earthquake on Illinois.
R. de Haan;
If I was in the Netherlands, integrity of the dikes would be my first concern! Any issues there?
BTW, an English grammar hint: lose the apostrophes. You’re way off in la-la land on them.
NEVER for plurals, e.g.
Noun possessives, and abbreviations of the words “is” or “has”.
NOTHING else.
7.3 in Fiji – more than 300 miles deep. Is that atypical? It seems so.
Thanks for the grammar tips Brian H.
As for the integrity of the dikes I don’t think they have a problem at this moment in time.
The quake took place at the eastern part of the Netherlands at the German border.
Besides that, all the dikes are checked constantly.

@R de Haan:
Most Dikes I’ve met have had a lot of integrity, and nice leathers too ;-)
Wow! 413 quakes on the California map AND a large cluster in Central America and southern Mexico… AND increases all over the globe.
Hmmmm….. Wonder what’s up…
