WOW!

Blimmey

Impressive

I don't understand seismic charts at the best of times...as PuterMan will verify...but the way you put all that info together visually I can understand, it sort of matches my gut instinct to things.
OK...so we have these eq's moving north, along a fault line and as they do they are increasing in magnitude. So going back in time could these be a form of creep, or the jackhammer effect as I call it. In other words all the smaller ones down south travelled up the fault line and weakened it further up thus causing larger eq's?
Geologically speaking I am wondering if the base rock further north is different to the one south. Is it more 'crystaline' (Quartz based) at say the south end of the eq drifft? Or even vice versa would work too I think. I'm thinking resonance here. lease do not do 'homework', its OK, this is me thinking out loud

Thank you again....I have saved your link.

First: I shall be very annoyed if this is zapped as off topic as it is very germane to the thread and to the spirit of ATS. I hope that does not happen.


@PuterMan....couldn't leave the boss out now could I?


I am not the boss. Of course I think I am



But I could not help but laugh when it transpires that you have never experienced an EQ and live on the least prone EQ place in the World!


Not only least earthquake prone but also 100+ meters a.s.l. so the ice can melt and we will be on an island!

We do have 'hurricanes' here. It made me smile when I saw Florida at 951 hP. We have had 955 hP here and 120kph wind.


I see you as a man living in a beautiful fishermans croft, with a view of the sea, on the beautiful west coast of Ireland, in idyllic setting, by contrast surrounded by computers and technological gagetry......but a man who forgets to take a daily walk, or have a glass of wine in his garden.


Can't quite see the sea (small ridge in the way), but see the islands on the coast. Computers yes. Other technical gadgetry - not really. Walk - well not at present, and don't really drink - alcohol and I have a mutual dislike for each other.

But to the real point here.


This is your thread, and I know I have come 'left field' here with this post. If you wish that I do not post here again, that's fine as I have the utmost respect for you....but please let me look as I too am still learning.


This is not my thread, it belongs to ATS and ALL the people who contribute to it of which I am just one. To even think that I could prevent you from posting/looking is madness. You, and any member, are entitled to post here or look (non members as well for looking) provided when posting the subject is related to earthquakes and it would not make the slightest difference if I did not want you to. That is not my decision.

Of course I would crank up the verbiage to drive you away however if I thought your contributions were worthless, but then I really should not judge that either.


We are all learning, including me. Point in question? Susan Frey said thunderstorms. I had not considered that. I learnt only yesterday that a 32ft organ pipe - and all the other lengths - is related to the distance a sound wave travels in a second. I have played organs since I was 17 but never put 2 and 2 together until yesterday - 45 years later on. Yes indeed we are all learning.

This is just as much your thread as my thread. Never forget that.

The signature does not look like thunder; it is building up gradual (Fast) last about same 5 minutes and goes down gradual. Same duration days before and after. Vertical arrays in boreholes does not show anything strange.

Only the later dates shows less time between pulses? Increased activity?

I wonder if this might be an related issue. The Mysterious Humming sound. Some time ago there were a number of reports from Memphis area up to Seatle; presently it seems not to reach media anymore. In one report the people said the noise lasted 5 to 10 minutes and sometimes comes back an hour or two later.

I have tried but I am not a sound savy person. Wonder if Puterman have a Audio kind of reader to try converting this from graph to Audio file? don't even know if such is possible

Listen to the sound files on that one as well. Actually I never thought to look and see if the is a railway near this one, but although the signatures are similar they are not identical.

In both cases you increased speed by 100x ?
There is a difference between these and the trains in your second reference.

I am going to doe-doe now, will think and tomorrow dig up some old copies I made from a collection of "The Hum". Many of the recodings that people did make is not reflecting the real audio because of LF and electronic failures. In general the analysis placed it around 20 to 70 Hz with majority in UK at 56 to 58 Hz. Your electricity is 50 Hz. Somewhere I have a filtered version to isolate the humming. It would be very interesting if this vibration is now picked up by some heliocorders!

Train? Might be, we will need to build an history of rumbles per day and hours at least over 7 or 14 day period to verify that option. Railway about 40 km away to West. I wonder - 3 to 4 minutes peak for train to pass by would be a long train or very slow? Then some of the 'spikes' are only 5 minutes appart in last two days; if fast running trains they would not be that close? I also hear a high tone whistling sound some places; might be my earphones or speakers.

EDIT: In review, the spacing might very well indicate trains or similar.

I guess I don't need to look at it then!

10,000 quakes in 3 days? Europe can still show America (Baja) how things are done!

So - Magma rising? Does not sound good.



But is it Magma Rising,or is a Fault beeing triggered/activated (because of Northward Direction the Swarm is taking)

Swarms in that particular Location aren´t really new,i think. But the Intensity (Amount of Quakes) and the "sudden" Change in Direction is a little disturbing. Would be nice if you could take a look at it,and see if its a Intercontinental Fault beeing opened,or if it is indeed Magma or the like

And speaking of which, PuterMan do you have a validated audio file of actual magma intrusion to compare it to in the first place? I'd be curious to hear that. We've heard the HT whale whistle sounds, but what if there is no resonance and it is just good old fashioned magma intrusion, lateral dike style?

Eh? I think you are getting two post strings mixed up! I never said anything about audio in relation to Shenon's current topic, that was in relation to Arkansas. Having said that yes an audio file of a dyke intrusion would be good. I will see what I can find. Unfortunately the Icelandic ones are not available only BORG which is almost as good as having nothing.

I never said you did, and no I am not confusing topics! Is why I was asking. I'd be curious to hear anything like that, where a harmonic tremor was not involved, but yet it was known magma intrusion. And of course if you are going to try and compare the 10,000 event swarm in Czech, you would need to have a known audio file of similar intrusion, no? Cause it clearly is seismic- the question is, what KIND of seismic.

OK, maybe I misunderstood what you were saying. Yes I need to get a waveform of a previous event.

This is a very interesting document in it's own right


[4] When magma is intruded into a dike, a swarm of small! to moderate!sized earthquakes (i.e., with M < 6) is commonly observed, which provides indirect evidence for occurrence of a rifting event [e.g., Sykes, 1970; Solomon et al., 1988]. Because rupture propagation generally occurs unidirectionally along a vertical plane, the process of Mode I opening during a dike intrusion is in many aspects similar to that of Mode II fracture during a strike!slip earthquake [Pollard and Segall, 1987; Rubin, 1992]. The major difference with “dry” seismogenic
rupture is that dike intrusions are slow events, because the velocity of propagation (of the order of 1 km/h versus 1 km/s for earthquake rupture) is limited by viscous resistance of magma during transport from the source reservoir to the crack tip [Spence and Turcotte, 1985; Lister and Kerr, 1991]. As a consequence, propagation of a dike can be considered nearly aseismic. Also, the lack of large

What's up on the German-Czech border?

Ea rthquake swarm in west bohemia

The Geophysical Institute, Academy of Sciences of the Czech Republic says it has recorded almost 10,000 earthquakes during the last three days in West Bohemia, a region located close to the Czech Republic’s western border with Germany. The earthquake swarm started late on Tuesday and continued through Friday. While many have gone unnoticed by the local population some of the larger tremors, including eight quakes exceeding 3 magnitude have been felt in the towns of Chemnitz, Karlovy Vary, Birch, and Luby.

The most recent earthquake measured 3.6 magnitude on the Richter Scale and hit at 0645hrs GMT on Friday at a shallow depth of three miles. The quake epicentre was located 81 miles (129 km) NE of Nürnberg 82 miles (131 km) SW of Dresden, 90 miles (144 km) W of Praha, 128 miles (204 km) NW of Budejovice, 131 miles (210 km) NNW of Schärding, and 227 miles (364 km) NW of Wien. Commenting on the latest earthquake swarm, the Geophysical Institute, Academy of Sciences of the Czech Republic stated: “The activity started in the evening of 23 August and is almost continuous till now (26 August morning). Almost 10 000 events were recorded in total up to now.

Already eight events M>3.0 and 200 M>2.0 occurred. The location of hypocenters directly below the NKC station, so it appears a new patch of the fault plane is being activated.” In recent years, scientists have noted an increase in the movement of magma towards the earth’s surface in the Cheb Basin, western Czech Republic. They say rising magma could be one of the causes of the earthquake swarms, which regularly occur in the Vogtland, North-West Bohemia, the Fichtelgebirge and the Upper Palatinate. The last earthquake swarm to occur before this week’s activity was in 2008.

Rising magma? Is there a big volcano in Europe that I have not heard about?

Update : apparently it's the volcano Eisenbuehl... can't find much info on it.

Update 2 : OK I fail, it seems it was already posted here... sorry fellas.

Ha Ha I had already done it using CZ.KHC..EHZ because I can't get the others. Unfortunately whilst I am going to put the link here this is 13 hours of data at 40 x speed. Be warned it 9 MB

CZ_KHC _EHZ_20110827-000000_4000Hz.wav

Normally I would cut a piece out but I was not going to use it so I left it raw and unfiltered - and full length. It is quite what I would call 'clean' i.e. not much background sound other than the quakes. This runs from 00:00hrs to 13:00 hrs today.

A frequency analysis however indicates 2 to 5 Hz which is good news as that pretty much means it is tectonic and not magmatic.

ETA BTW: Here is the seismogram from the station I got the sound from: KHC.CZ..EHZ.2011.239

NOte by the way that the sounds on the other site are from 2008. Actually to be honest I could not hear them.

From article above, posted by Vitchilo:

So if it's not intrusion, according to your frequency analysis, but yet "rising magma" still could be one of the causes, then to me that means it might be an expanding magma chamber. When those happen, pressure from steam and gas trapped in the chamber can cause the rock above it to start fracturing, or uplift- or both...

Yes....lightening. It would cause the electrical sig, obviously. Wonder if it was in Virginia too what was that, yesterday? Only thing....would it really last that long? I mean, yes a storm could last that long but would it cause a steady 'signal'? Interesting stuff.

Oh...and I have always pictured you as someone not surrounded by gadgets, but one reliable beast to tap away at and then outside with a cup of coffee often to listen to good ol mother earth in 'real-time'.

It would be good to have GPS or interferometry of the area.

I will take a look around.
