  1. Thanks @ Jón. That are really impressive videos. Great idea to fill your writing break with this!

    1. I am not allowed to see the first video in my country. 🙁 The music from the second one could only be from Sigur Ros? Fantastic!

  2. @Diana, Thanks for letting me know. I will replace that video with a video that everyone can view. The first video also has music from Sigurrós music band. But that is the reason why you are not allowed to view it from your country. 🙁

    1. The second video has Sigurrós music in it. You should be able to view that video. There is nothing but natural sounds in the third music video.

  4. @ Jon – What are the noise on your helicorders? There is not much wind (~2m/s) but the helicorder shows some disturbances. Human made or is the windmeter wrong? Seems to erratic to be tremors..

    1. This is wind noise. Some wind directions are worse then others. In this case the North East wind appears to be the worst direction I can get. Then there is no need for a lot of wind to make a big noise.

  5. Tremors are again increasing around Katla & Vatnajökull. Also some deep quakes north-east of Askja.

  6. M4.8 in Iceland!!!

    1. But it don’t appear on the emsc side and there is no green star.
      @ Jón: Was this a false measuring?

    2. This earthquake is a error. You can tell by low quality and the fact it did not show up on my sensor or IMO network at all. A earthquake of Mb4.8 also appears on EMSC and USGS web site.

      I ignore those false earthquakes.

  7. Jón: Maybe this was a false one, but all the others at Vatna and Mýrdalsjökull?

  9. well the earthquake is still on the earthquake site………..
    wouldn’t they have removed it by now or do they just leave them there even
    if they are false? But almost a 5, well that would have turned up on everything!

    1. This error did happen because of the ML2.3 earthquake close to Krýsuvík. You can tell by the time difference on the earthquakes (just a few seconds).

      Even the ML number is high, this earthquake (ML4.8) is still a error. IMO might not remove it at all, as it didn’t happen in reality and the results on there web page is from a automatic data collection.

  11. “”Where’s the kaboom? There was supposed to be an earth shattering kaboom”

    Marvin the Martian – Bugs Bunny.

    Something’s missing…. aftershocks. There’s less seismic activity in the 2 hours afterwards than in the 2 hours before.

    Definitely supports that “error” idea.

  12. Well, I don’t consider myself to be qualified to state anything as fact.

    For all I know it was a cobalt bomb and we are all just waiting around to keel over.

  16. Jón: There was an earthquake at Laki on Thursady (small, though), but Vatnsfell, the corresponding station, also showed some anomalies in the past days. Could they be explained by water flows, or could it be some magma on the move?

  17. With the constant eye on quakes in a volcano populated area… some times you loose context when chasing quakes around the plots.

    For the sake of comparison, here is a plot of the quake energy in Iceland with the quake energy of a groups of interesting quakes in Arkansas.. land of the razorback. (not something you want to run across while tromping through the bottom land)

    http://i53.tinypic.com/2yla4qv.png

    For the casual observer… Arkansas doesn’t have any volcanoes. Well, doesn’t have any recent volcanoes. It’s been a few million years since any of that has gone on. It does have the New Madrid “failed” rift system and possibly some intrusives along the edges of the rift, but they are also ancient. Most of the recent activity is along the Commerce Fault that lies on the western edge of the rift system.

    Lurking,

    Another area of interest is Southern California, USA. In case your not aware, there have been some interesting developments there in the last 6 months. As you may know, there was a 7.2 EQ about 100 miles south of So. Calif in April 2010 and since then there has been an unusually high frequency and longer duration of after shocks that have been migrating NW up to the 3 major faults in So. Calif – San Andreas-SAF, San Jacinto-SJF and Elsinore-EF. The after shock patter is anomalous. Scientists are scrambling to put data together to understand how this build up of stress is likely to play out. Right now, the smaller/newer faults, SJF/EF are grinding away and unable to hold much stress and in recent monthss, are having a hundreds of small EQ from 1-2 range with many 3-4′s and a 5.4 on the SJF in July.

    Just like in Iceland, all this comes after a decade of subdued activity on the precipice of increasing activity. In the last 3 days, EF has had 3 EQ in the low 3′s all along the fault. My concern is that the EF, which is very overdue per scientists, is receiving the brunt of this stress and perhaps is getting close to having a large snap. If this snap rippled upward into Los Angeles to the connected Whittier fault, this could have serious implications so So Calif. The SJF has also been very active in April 2010 and it is a candidate for a large break. There is a body of sceismologits that are concerned that the SJF, which is connected to the mother fault, SAF (capable of 8.0 or larger and predicted to yeild the “big one” of 7.8 or greater), could produce a large enough quake to trigger the SAF which is also very overdue and has build up considerable stress without a break in the last 160 years. Also, there is concern that the SAF could also trigger the Barstow fault. If the SAF were to break, the impact would be catastropic for So. Calif. The scenarios based on scientific reseasch are frightening. If the SAF had a mega quake as predicted and especially if this triggers the Barstow to break (some scientists subscribe to this theory), So. Calif would be isolated. Major Rail/Transpotation corridors (Barstow is the major rail hub for the Southwest), Nat Gas piplines, Petroleum facilities, Power Grids and the Calif Aquaduct bottle neck right into the heart of the worst part of the SAF and Barstow. Not the mention that the Port of Long Beach and Los Angeles where there is also major refineries are expected to sustain heavy damage due to liquifaction. So Calif in this scenario is like Haiti, cut off, isolated with an infrastructure so damaged that the authorities would be unable to care adequately for all those affected.

    Studies show the death toll estimated to be around 1,500 to 5,000 with 200 billion in damage and a long protracted recovery period due to infrastructure damage. The very fragile So. Calif economy, which currently is much worse than Greece and about 14% of the U.S. economy, would likely be all thats needed to drag down the fragile U.S. economy into a recession/depression, then trickling down to world economies depending on the coupling (watch out Chinese bubble makers).

    Not to be an alarmist, but even if this does not occur, if you add the coming middle east war which is most assuredly going to occur before summer next year, I don’t see a way the U.S. can escape another recession with the more likely scenario of a depression given we are completely and utterly bankrupt with heavy debt. All what if’s, of course 🙂

    Scientist have now put the percentage likelihood of a major SAF quake at 99.9% in the next 25-30 years. It is considered to be at the end of its loading period storing up over 33 ft of movment without breaking. Given the tenousness of the U.S. economy in the next 5-10 years, if any of these events occur, the word recession could seem mild.

  19. @RonF

    Yuppers. A few months ago, I tracked what I refer to as a \stress wave\ up the Gulf of California. This was indicated (to me anyway) as a flurry of activity that kept showing up about ever month and a half or so, 145 miles North of the previous activity and along the central fault in the GoC. The start point that got my attention was the Mag 6.0 at 25° 7.8’N – 109° 45’W.

    This went on until it got to SoCal and I figured I had lost it in the the myriad of fault blocks in SoCal. There was a bit of activity on the South end of the Salton Sea, but nothing I hadn’t seen in the previous two years or so. About the time that I figured that this \stress wave\ would be North of San Diego, the Mex 7.2 goes off. Ever since I have been watching the aftershocks trying to work their way around the Yuha Wells fault (transverse oriented) from the Laguna Saluda segment to the Elsinore proper. I was unaware of the Barstow risk.. that bit is new to me.

    I do know that there are several lift stations that have to get the water over the transverse range being lifted at the Garlock fault zone, and to bypass that, a lot of it goes down the Owens Valley… the southern end of which had a flurry of activity a few years ago. Dunno if that was associated with the nearby geothermal systems, but it was rattling quite regularly for a while there.

    Anyway, all this led me to do a rather odd plot.

    http://i51.tinypic.com/2jcj8gj.png

    This is just a full length plot of all quakes within 100 miles of the San Andreas (or it’s cohort from the Imperial and south) I sliced off everything south of 30°N in order to get the scale to this level, but it actually extends all the way down to the Rivera microplate’s triple junction. The problem on that segment is there is not as much equipment watching, so there are fewer quakes.

    http://i52.tinypic.com/2lvfwut.png (full version)

    In these plots, you can make out trends of quakes moving up and down the fault zones. The bad part about this is that as humans, we see patterns in everything. But it’s an interesting plot. I never was able to determine anything from this, even zoomed in to a really tight time-scale (a year or so). But you can see areas that cluster quite often.

    Eh… this thing hasn’t even been updated in the last few months. But here ya go.

    1. Interesting stuff Lurking. I am just an avid reader and have a brother who runs a research facility in the area in which there are many geologists he taps into. I read alot, share it with my brother and he gives me the benefit of all his conversations with the geo dudes. I will share you post with him. He tells me they are pouring a lot more funds into the data collection/sensors/etc especially since the 7.2 El Mayor and that there is a flurry of seisomologist activity studying the developemts at these faults since the 7.2 as the pattern is s/w anomalous and concerning. Every week I look at USGS I see a wave that starts below the Laguna Salada and then works its way up to the border and into Calif, most on the EF fault. The sister faults of the SAF that traverse the Salton Sea and into Brawley are becoming more active now too. I just get a weird feeling one of these is going to snap in the next year or so.
