Mystery Volcano Photo #22

Maybe I should be pleased that in the last Mystery Volcano Photo took a whole five guesses rather than one or two, so I count it as success! The correct guess was made by Dr. Boris Behncke, so that elevates him into a tie for first.

Current Standings:
The Bobs – 3
Don Crain – 3
Boris Behncke – 3
gijs – 2
volcanista – 1
Lockwood – 1
Elizabeth – 1
Ralph – 1
Anne – 1
Cam – 1
gg – 1
Damon Hynes – 1
Marco – 1
Doug C. – 1
Diane – 1
Stephen – 1

The 21st MVP was submitted by Eruptions reader David Tucker, who snapped it while flying over the Kamchatka Peninsula on his way to Japan. The volcano in question is Krasheninnikov, a fascinating looking system where two stratocones sit inside a larger caldera of Pleistocene age. The last known eruption was potentially as recently as 1550 AD.

So, with that, we’ll move onto the next MVP, lined up for the holiday weekend (here in the U.S.), here it is MVP #22, submitted by another Eruptions reader:

    Some complex dome system! At first I thought it might be the Santiaguito dome at Santa Maria, but none of the photos match the skyline.

    Papandayan = sulfur deposits. Nope.

    Mt Meru it is.

    *shrug* Note the exact same photo appears in the Wiki page?

    Erik, you’re going to have to use non-file photos from now on.

    Different photo, same vent, slightly different angle.

    http://www.tanzania-adventure.com/mount-meru.htm

    Interesting to see that the vents were recently active (1880s and 1910) after a very long hiatus.

    A question, How do you know a volcano erupted potentially as late as 1550 AD?

    I must add I do enjoy your blog, though more often than not there words and ideas i do not understand. Would it be possible to throw in a definition or two once in awhile.

    Steve, Leeds, UK
    It is Meru,Tanzania.
    Is there any way photos of volcanoes can be included that are no elswere on the Web, as this is getting very very easy. May be posting photos of volcanoes from your own private pictures. This would make things far more interesting, and be able to see volcanoes from different angles and perspectives.

  19. #19 Bernard Duyck

    It’s Mount Meru – Tanzania

  20. #20 Renato I Silveira
    July 3, 2010

    #18 Congratulations to the winners. I agree with you, Stephen, but, still, we need to check on existing pictures, otherwise, how would we ever guess?
    Of course, if the exact match for the pic is already somewhere on Wiki, or SIV, it becomes too easy. I liked this one because I followed some clues given by the surroundings and I came to this pic on SIV of Mt.Peuet Sague (take a look and you’ll see some similarities). At first I thought of Santiaguito, but I knew it should be a complex volcano.
    Anyway, I find this very amusing. Thank you Erik!

    A bad day for volcano watching: it’s either cloudy, night, or cams out of order (one for El Popo out and the Taal Lake cam keeps switching between two frames). The only one going well is Turrialba.

    @Lavandel,Switz. Good morning, also Kultsi – I finally read late yesterday that this weekend is a big ‘holiday-without-a-Holiday’ weekend in Iceland – everyone heads for the country – which I suppose includes the Mulakot airfield area . Not so warm, tho,’ 11º and cloudy, with rain in other parts of the country. Here it will be 30-35 the next few days. ecch.

    Hi to everyone !

    Looks as if most of the folk at the Mulakot Bash are keeping inside and can you blame them ?!!! At least they are not being “ashed”.
    More to the point,interesting activity on the Godabunga Helicorder on the 2-4 Hz band and six small ‘quakes at varying depth around the God station.Wait and see as always !

    Happy 4th of July to all the USA people who might be aboard.

    The people at Mulakot seem to have gone now. I had the opportunity to watch some of them put up one of those pop-up things and put it by the house. That was in the second frame. The pop-up is gone now.

    I guess there isn’t much going on right now. It is going to be hot here today and it may get up to 100deg! I know it will in the Central Valley. I am staying in even though there will be a parade in town and some fun stuff at the park. It is just too hot. A few years ago I was there every year having fun. Well, I will just have fun at home and watch the birds that I feed and stay cool.

    Have a good day everybody!

    Cheers

    How do you know a volcano erupted potentially as late as 1550 AD?

    B Elias 17; since nobody’s has yet answered, may I try?
    The method usually employed is Carbon-14 dating. The radioactive isotope C14 is present in living organisms; the ratio of C14 to stable carbon isotopes remains the same while it’s alive, but on death -eg by being turned to instant charcoal under a lava flow or pyroclastic flow- the ratio starts to change as the C14 decays. Method useable up to 70,000 years or so (I believe) but the accuracy is best for more recent dates

    Other methods include; anthropology eg buried archaeological sites, or local tales of a recent eruption before the arrival of Europeans (1550 is about the time that many volcanoes were seen for the first time by Europeans)

    Then there’s tephrochronology; ash from an eruption which is found between layers of ash from already-dated eruptions can be located roughly in time (for convenience, GVP takes the median date, but obviously the eruption could have taken place at any point in that interval) This may be what you were thinking about; unknown ash lies under an ash layer dated to say 1552 and above one dated to about 1450. ‘Median’ date would be 1500, but the eruption COULD have taken place as late as 1550

    A few other methods are available for relatively recent eruptions, but need rather special circumstances to work. Like dendrochronology (tree ring counting) and varve count (ash layers within a sequence of annual sediment layers -varves- on a lake bottom or such

    If an eruption can be dated by more than one method, so much the better

    (apologies for not using the superscript for ‘C14′ my keyboard isn’t up to it)

    Along those same lines, the mineral zircon is tough critter.

    It also tends to carry traits indicate what sort of environment it was in when it formed (presence of H2O, depth etc.) Inside the mineral, bits of uranium can be found and when analyzed for the Pb/U ratios, can give a rough date of how old it is. From what I’ve read, this is workable for rocks much further back in time. (millions to billions)

    Hi Renato 40 – think it is just clouds, I usually check the combined-FLIR camera at http://www.flir.com/thermography/eurasia/se/data/?id=30533. The glacier looks quite free of ash where it falls into the riverbed. But you can I think see that the rest is evening clouds/fog. Hope Brasil is recovering from its FIFA loss.

    @Birdseye #41 Hi there! Thank you for the link. I think many people have posted the same question, but as it keeps flowing in a steamy way, I was just wondering if that crater lake from which I’ve heard no more, was making its way through Gigi.
    As for the second part of your post… er… I’m recovering pretty well, not a soccer freak myself, but what amazes me most is the grudge against Argentina. People here were commemorating as if it were Faschingsdienstag in München.
    The problem was solved by an American journalist:”Brazilian football lacks samba!” I agree. And leave the Tango to Dieguito. :)

  49. #49 Lurking
    July 4, 2010

    That’s actually about 12 to 13 days of activity.

    I can’t state that it’s tectonic in nature… an artifact of stress moving along the various faults/fissures, or a bit of magma moving about. The proximity of the fissure site, and the two volcano’s… with a recent eruption of Eyj have me wondering it’s a sill or dike like flow. If it is, and it broaches the surface, then it’s new vent time. But before anyone gets excited, there was FAR more activity than this when the original eruption happened. This is a creaking rocking chair by comparison.

  50. #50 parclair, NoCal USA
    July 4, 2010

    @Diane– was Magma:Volcanic disaster the one where the geo team goes to a newly erupted volcano and digs an ancient fossil out of the newly-laid-down tephra? Or, is it the one where some guy keeps having visions of a woman warning him about an impending volcano in an Italian village (filmed in eastern europe, I think). Both v. funny. ;-)

  51. #51 Renato I Silveira
    July 4, 2010

    “This is a creaking rocking chair by comparison” – There was this time lapse graph you made during pre-eruption swarms that gave me the true dimension of what should we expect before a real magma move is on its way. These sound like distant echoes reverberating in the pipelines.

  52. #52 Lurking
    July 4, 2010

    I think the time lapse was done by a French site. The only animation I did was a spinning view angle that I never posted here. It looked like warmed over fecal matter. I have been fiddling around with Dplot and if I ever figure out how to append 4D data I can step through the set and make that sort of animation. Dunno how I would put it up for viewing though. I might have to do as an animated gif. Never had a reason to do Youtube.

    I did note that there was a massive accumulation of ~5km deep quakes halfway between the fissure eruption and the Eyj caldera, and then they just shot across and went pop.

    Carl’s vortices idea would be really bolstered by the shape of the quake stack for that. A very graceful spiral, as quakes go.

    Dunno if you can make it out, this is a black background version of a lot more data, and there are at least two or more of those spirals intertwined under Eyj and the Fissure area. The graphic I am remembering was before the main Eyj eruption happened. This has quakes from before and after.

  53. #53 Renato I Silveira
    July 4, 2010

    Yeah that’s the real thing! But I noticed the latest EQs reaching deeper foci, just thought they were within an average level. In fact I would love to see early graphs of “normal” EQ activity in Iceland to have a basis. As compared to, let’s say, California or Alaska, it seems pretty calm to me, but there are days where you see those little red spots all through the rifting system in Iceland and it gives me the chills.

  54. #54 Renato I Silveira
    July 4, 2010

    This is an amazing graph indeed, Lurking. You can almost “see” the lava rising up to the rim.

  55. #55 Kultsi, Askola, FI
    July 5, 2010

    @Renato [40] -

    There’s often steam coming out from the lava trench quite a bit down the slope of Gigjökull. Whether that is caused by hot water flowing down or cold water/ice getting on the still hot lava flow, I cannot say.

    The crater lake area is steaming happily, and I think every now and then the water gets splashed over the rim, as there is heavy steaming in the uppermost part of the lava trench.

  56. #56 Renato I Silveira
    July 5, 2010

    @Kultsi Thank you for the info. I really thought the lake was dead. I’m happy it isn’t, but still there’s the threat of it coming in contact with some residual magma that eventually may reach the rim.
    Well, that’s it for today. I have a looong week ahead.
    Good night!

    I guess this graph goes down to 15km? Or is it 30?
