  1. Thank you Spica, that’s one interesting read! Volcanism in Turkey sounds really alien to me, but obviously, there is more to it than most of us think.

  2. nice find ! what is the origin of this volcano ? because it is in the middle of the country, not near a subduction spot….

  3. Spica – very nice find. I spent 6 weeks operating out of a bare base near Yenisehir Turkey some 30 years ago. Went back a second time for 3 months some 15 years later and operated out of Incirlik. Flew over the area of Hasan Dag and never knew it was there, though wasn’t paying much attention to the geology at the time. Rough part of the world. The eastern border of Turkey was the epitome of a border junction with lots of people who didn’t much like one another – Turkey, Syria, Iraq, Iran, the Kurds and the Soviet Union. Cheers –

    • Too lazy, but the scientist Armann Höskuldsson of the Reykjavik university says the moderaste eruption of lava from such a system of Bárdarbunga’s size usually lasts several years, even decades. Therefore the danger is not over because of pressure in the system that can now be building up without the safety valve or Holuhraun and 100 to 200 cubic km magma still below the surface.

    • Hi Woodstocksj, most of the article is a summary of Bb’s, but I translated tthe last paragraph for you:
      According to volcanologists, however, the slowly closing fissure means increasing risk: So far, the volcano has been continuously releasing pressure; now it might be building up more pressure inside, which could eventually discharge in a really violent eruption. In a lecture to students Höskuldsson had recently emphasized the development around the Bardarbunga must “now let the alarm bells ring.” With some certainty the event is not over yet.

  4. Villarrica’s alert level has been raised to Orange yesterday and to RED today (2015-03-03). About 3,500 people have been evacuated so far, and the latest violent eruption at 3 a.m. this morning has caused many more people to flee their homes.

    Great Video from 24HorasCL:

    Several roads remain closed. Witnesses noticed the increased flow of nearby rivers which is a result of melting of the perennial snow covering the mountain massif, which in recent days had been an unusual actiity. The most affected localities are Pucón, Villarica, Coñaripe and Panguipulli, all situated in an area of​great tourist influx. The column of ash and particles than three miles high, many routes remain cut, although the main routes are kept free for falicitar evacuation, said the National Emergency Office (Onemi). Classes were suspended and several schools were enabled to house evacuees by the eruption of Villarrica, whose activity has decreased after the initial eruption. […] The ash from the volcano also crossed to Argentina. – http://www.lanacion.com.ar/1772968

  6. Wow! Villarrica is putting quite a show, Etna style! But it looks like authorities are concerned with lahars and a threat similar to that from the 1971 eruption.
    Thanks Granyia for the updates and Spica for the post.

  7. And here a real hammer – webcam time-lapse video of before, during and after the Villarrica eruption, from the first tentative coughs to the full bronchitic roar… or rather strombolian roar: http://youtu.be/LTWfxOxuIGA Video by POVI.

  8. I just looked at volcano discovery and found that there are 18 of them in Turkey and that none of them are on alert.

  10. Are there others of you who paint, knit, draw, build etc. volcanoes? That would be an idea for a post in the Volcano Arts section!

  11. Update on Villarica
    Gathered from various actual newspaper reports (March 5 and 6, 2015):
    – SERNAGEOMIN reports that the activity of Villarrica has decreased considerably. The red danger zone has been lowert from 10 to 5 km around the crater. However, low tremor and small strombolian activity are still ongoing.
    – Evacuations are stopped and people return gradually to their homes.
    – Locals are worried: as this had been such an unusual short eruption, they are afraid that the vent might be obstructed and more vigorous explosions might occur, as has been seen in history. However, they are reminded by their authorities that now scientists have much better means of predicting the behaviour of the volcano and can be trusted to give the right instructions.
    – Luis Lara, volcanologist, explained that in the earlier overflight a partial obstruction of the duct had been visible, but mainly the the crater was still open to allow degassing. Therefore the probability of intense energy pulses is relatively low. An eruptive activity that could happen would be smaller than that observed early on March 3.

  12. May I ask, what has happened to Sinabung?
    I couldn’t find new reports, just a tweet saying that the lobe is collapsing.
    AND: Thank you for your patience with my silly questions!!!!

    • Thanks for the hint! There has been another large eruption yesterday… as far as I can understand from this garbled translation it must have been pretty bad. Apart from the lava dome collapsing, PFs, lahars and sulfur smells, this eruption also caused huge forest fires which led to flight disruptions (the smoke).

      This is from a lengthy article, but the translation is very hard to read:
      A large eruption occurred again in Sinabung, Karo, North Sumatra, on Thursday (03/05/2015) morning. Undermined lava dome that formed in 19 February eruptions. At least 1.5 million cubic meters of volcanic material, causing ash thrown up to a radius of 10 kilometers and avalanches of hot clouds as far as 4.7 kilometers. Head of Observation and Research Volcano Western Region Center for Volcanology and Geological Hazard Mitigation (PVMBG) Hendra Gunawan said, lava dome collapsed after power driven eruption of stomach sizable crater.

      Btw, I hope you have no problems with the login? Just thinking, as your name is changing so often?
      EDIT: No, the flight disruption was caused by volcanic ash, not by smoke from forest fires. Translation error! :/

  13. Bardarbunga at last look really seems to be dropping dramatically earthquake wise.
