Volcano of the Month + Riddles

A while ago it was suggested that we should have a volcano of the month competition. I think that is a good idea, that way we get a record of which eruptions or volcanoes have been noteworthy in a gallery.

Of course some volcanoes will pop up often, but that is just good since they then merit greater attention from us who are writing the pieces on this blog. If you, the readers, find a volcano interesting we should after all fulfill your wishes and needs.

After a bit of pondering between the editors we decided that we should first let our readers suggest names of volcanoes for the month for a day or so, then we put in a poll between the suggested volcanoes. And, after that we make a piece or two about it. Nothing to fancy, just good fun really.

So, get thinking about what volcano you feel has been the most noteworthy during January and if you write a short explanation to why it would be even better, after all you want “your” volcano to win don’t you?


This week there is a volcanic term hidden and 4 volcanoes. One of the Riddles is in the form a video. Look at the video and think what it could be.Sprängtporten

  1. Maar + Image – Yak Loum in Cambodja (Cryphia, 2pt)
  2. The last sunset in the world – Savai’i in Samoa. The volcano closest to the dateline. (Dorkviking, 2pt)
  3. Five peaks of Mount Nose – Mount Nasu with it’s five peaks (Sissel, 2pt and Bobbi, 1 bonuspoint for Monte Nasone on Monte Somma in Italy)
  4. Dual passport volcano next to talisman – Volcán Tacaná, Guatemal-Mexico border next to Talismán Bridge (Cryphia, 2pt)
  5. Video below. Clue: Think Iceland – Jökulhlaup (Sa’Ke, 1pt)

  1. And something to wake up too…

    The closest I have gotten to this is seeing a member of Hells Angels driving down the motorway wearing a pair of low rider black leatherpants, the west and a pair of pink laced ladies underpants. Was also a spectacular fail of him. And watching the buttocks move with the cylinderstrokes was making me reach for the soap to wash the sight out of my eyes.

  2. Earlier in this thread there was a brief, yet quite illuminating exchange of comments (by Bruce, Henrik and Chryphia) about the nature of the bubbles which respond for the strombolian/vulcanian types of eruption. Since we have two volcanoes – Stromboli and Sakurajima – that keep our entertainment going most of the time, albeit there have already been excellent installments about them, I would suggest that we should revisit them in further detail, perhaps comparing their tectonic settings, nature of their magma and so forth. Can’t get enough of them! Besides the fact that they are among the best served volcanoes regarding availability of webcams. Thanks dragons!!! 🙂

  3. And a last, desperate try for nr. 5: Highway from hell – a term for a conduit from the mantle to the magma chamber through which magma can move very fast upwards.

  4. Hi

    This is the deformation variation update using some of the GPS stations on El Hierro.

    The values have been smoothed using a moving average on 96 h. I have let the last picture last longer for a better view of the evolution.

    Values go up to February 8th.

    The situation seems quite stable.

    Valuesfor HI 08, HI 09 are regularly updated, as well as HI02, HI03 and FRON). For the other stations (HI00, HI01 HI05 and HI 10) the values have not been updated recently, so I have kept the last published value.

    Of course this situation introduces some incertainty in the result.

    The values come from the public GPS charts on the IGN site. I have stopped using the charts from Nagoya university as nearly the same data is available from IGN (Nagoya univ. data would come mainly as double, except for VALV which could be used as a substitute for HI00).

    The colorbar on the side gives the elevation change in millimeters.

    The title bar gives the time span and the date.

    The same chart, but with no data smoothing (raw data) is also available on the same YT channel.

    Data from IGN and NOAA, made on Gnu Octave 3.2.4 (Ubuntu).

  5. #5 … synonym of run like hell = evacuate. Can this be counted as a volcanic term ?? … oh my goodness I’m not coming back until Carl gives the answer. Have a good day.

    • And nope, no correct answer to no five…

      “You run and you run,
      to catch up with the sun,
      but it is sinking”

  6. 5. Hekla going caldera, or something like that
    Other possibilities in Iceland: Bardarbunga or Grimsvotn/Laki doing a big one, Hengill (run, Reykjavik, run), Katla (run Vik, run)

    But Hekla is entrance to hell, so run like hell! Especially if you hiking it when it starts to shake.

  7. This afternoon I began the first hike of the year, after months of non hiking. Such a nice experience.

    It was a beautiful weather, 0ºC and sunny calm, and hard snow perfect for hiking.

    Our choice was near Hengill and Langjokull, along the Kalfstindar and Laugarvatnfjall volcanic region (we went 3 people) up to 700m high. These belong to the sometimes considered Hognhofdi central volcano (GVP wrong assigns Hveravellir central volcano but that one is much far north) Area was last active some 3000 years ago.

    We could see 20 active volcanoes from the top!

    Due to excellent weather, these are visible from the top of the mountain we hiked: Surtsey and Heymaey (far away in the sea), Eyja, Katla, Tindfjallajokull, Vatnsfjoll, Hekla, the rims of Torfajokull and some mounts far away in the Veidivotn region (Bardarbunga is central volcano but not visible since it is quite far away), then Hofsjokull and Kerlingarfjoll are visible far in the north horizon, Langjokull and Hveravellir central volcanoes under the glacier further north, Hengill and Hrómundartindur nearby (we could also see the region of Grensdalur but this volcano is dormant in Holocene), Blafjoll far into the southwest. Grimsnes volcanic field nearby. Of course we were in one volcanic field of its own, the Kalfstindar-Hognhofdi. And also very close to Geysir-Laugarfjall volcano (this one uncertain since it always has been dormant in Holocene)
