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


  2. Beautiful eruption in chile. Some of the people seem to be enjoying their fire mountain to a degree.


  3. 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!


  4. 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.

  5. 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! :/


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