Geophone network computer update complete

I have finished updating the geophone network computer. Everything is now back to normal and the webicorders should now update normally.

There are minor issues remaining on my geophone network computer. But that is related to lack of hard disk space. That issue is going to be fixed on later date.

  1. Well I’m glad that worked out.

    I just recently went though a forced upgrade. Seems my motherboard decided that it no longer wanted to count memory. No memory, no load. No POST matter of fact. I was running Win2K server as my main unit on an AMD64. (yeah, yeah yeah, 32 bit O/S on a 64 bit CPU… but I never got around to the newer zippier O/Ss. WinXP was 32 anyway and I liked the server O/S better. I had greater control over it.

    So. Mainboard is toast. Tear it down and rebuild. Now I’m in an AMD Phenom II quad core with Win7. Lost about half my stuff (and some of my graphic ability) due to a drive getting cooked by an external IDE-USB device. The powerpack blew a cap and the drive went bye bye. Roughly a 1/4 full 1 TB drive. Pissed? Yep. At no one in particular. Stuff happens. My data files were on a Samba dive share from the machine in the corner so they survived the … “event”. (yay Linux) Main graphing apps survived the transition.

    So.. here is Grímsfjall Depth vs Magnitude 10/1/10 to 11/27/10 06: 17:54

    ( Ya know I had to plot something…. 😀 )

      1. Congrats to you both (Jon and Lurking (have you considered linux or macs?), i do enjoy following the blogs and attempts at understanding what seems chaotic unpredictability. All the best with the science, keep up the good work.

      2. I’ve built many Linux based servers and done a couple of custom gateway/firewall and document storage machines (for a client). Matter of fact, one of the reasons that my personal machine stayed Win2K was most of my interactions in the field were with that platform. My biggest problem was that I never used the GUI. for Linux. At the time, (and still) I felt that processor time was wasted on GUIs, a server should be a server and not using horsepower to position an icon or fade a desktop. I guess I’m a Luddite.

  2. Now and then I have been mentioning “on the fly” geothermal energy production.
    Something that exists at many places in the world. I have also sometimes sloppily mentioned it as Krafla-style geothermal plants.
    I would just like to clearify myself here. I am not talking about normal geothermal energy, I am talking about superheated critical stage geothermal powerplants through deep drilling. Ie, drilling deep down (3000 – 5000 meters) into areas of extreme accumulated heat. And with that means either into magmatic faultlines or close to magmatic reservoirs to achieve supercritical steam when water is pumped into either a drillhole system in areas of 450 degrees centigrade or into a deep cavernous entity.
    The first of these projects where the IDDP where famously they drilled into magma at only 2104 metres depth. Here is the homepage, where you can find sub-links to some 15 papers in the field. You can find links under both “Saga Reports” and “News” to the articles and summaries.

    So now you know that when I am saying geothermal energy and soforth I am talking about this kind of experimental powerplants, not the old style.

  3. What remains to be done is to replace the hard disk in my geophone network computer. The hard drive that I currently use is 120GiB (split 12GiB for Windows – that is too small and 100GiB for data) in size and is from the year 2006 or 2007. So the age factor now plays a big role in it.

    The drive appears to be working good. But the age can make a hard drive stop working without a warning, so a replacement has to take place soon.

    1. And since this thread is quite “techy” and nerdy…

      I have upgraded my volcano-chair tonight to get ready for the next eruption.
      I installed twin Electrovoice XLD281 15 inch elements into the seat of the chair to get the right amount of deep vebrating sensation in da buttocks. To run it I carried out my old pair of Nelson Pass Aleph-Zero mono-blocks (150 watts, 120 amps pure class-A).
      Both a screen capture though algorithm of Jóns helicorders and Yello Live at the Roxy ’83 gave a good massage to the posterior. So was also the case with Kinky Friedmans hit-single Knee deap in Tacos…

      I have achieved nerd-hood 🙂

  4. Before going…

    Jón, the last day or two your helicorders have been bopping heavilly and the maximum values are close to or the same as during Eyjafjallajökull. Do you know why? Which volcano is responsible do you think?
    I guess I will see the anser late morning, ah no, late afternoon…

    1. It is called human noise. It always happens when the owner of the summer house is using it.

      If it is not on the IMO web page and does not look like a earthquake. Then there is a good chance that it is a noise and nothing else.

      1. The soil there is mostly volcano ash and clay below that. So it is hard to prevent the pick-up of noise from human traffic around this area.

        I can see a car driving by up to 5 km away from the geophone.

  5. Another swarm near Herdubreid, could you give us some information about this seismic/volcanic active area, Jón?

    1. It is just a small earthquake swarm in Herðurbreid area. It is known for this type of earthquake activity. This area is outside fissure swarms from volcanoes. But it is quite close to the fissure swarm from Askja and Kverkfjöll, but without being inside them.

    1. If you deduct the swarm at Herðubreið (16 eqs of moderate strength at 4.0 – 10.0 km depth), there’s not much going on really. Herðubreið (and Herðubreiðartögl) has behaved like this since I started following Icelandic eqs in January, mostly quiet and then little bursts of activity like this one.

  7. Earthquakes again on the far east of Katla I see, if it’s magma movement, where is it likely to be going or coming from in that area?
