The Friday Update #3 (19/02/16)

Welcome to another Friday Update. 

I will start with the easiest of the reports regions to write about.  Europe, North America and Africa are continuing their quiet period with no reports of any activity from these regions.


This week saw a strong eruption from Zhupansovsky on the 12th of February, with  Volcano Discovery reporting a plume sent up to 34,000 feet.

Not to be out done, Karymsky continues to throw ash into the sky with virtually daily reports of plumes the largest I spotted was up to 20,000 feet


And Finally on the Kamcatcha Peninsula, we have Sheveluch which threw a plume into the sky up to 15,000 feet on the 12th of February.


Moving to Indonesia, Dukono continues to produce mild to moderate ash emmisions, according to Volcano Discovery and a Google translate of  says “Dukono in North Halmahera, North Maluku, thin volcanic ash this morning. Volcanic ash reached an altitude of 1,500 meters and then move toward the north and northeast”


Sinabung keeps producing its now familiar pattern of ash plumes and pyroclastic flows.


Over inside the Tengger Caldera, the Darwin VAAC reports that Bromo is continuing to emit ash plumes up to 10,000 feet.

Semeru had a large pyroclastic flow on the 14th reaching up to 4.5km from the volcano and emitting a plume to 26,000 feet, causing the Darwin VAAC to upgrade its aviation warnings to RED, according to Volcano Discovery


Volcano Discovery also report on Ambrym “Wellington VAAC reported an ash plumes from the volcano this morning. Based on satellite observations, an ash cloud rose to 9,000 ft (2,7 km) altitude and drifted east.”


In Japan, Sakurajima  continues to produce small explosive eruptions with the Sakurajima Eruptions Twitter feed reporting that volcano has its “15th (eruption) of the year” on the 17th.


Central America

Mexico’s Colima and Popocatepetl volcanoes continue as they have over the last few weeks, small explosions throwing plumes into the sky virtually every day.


In Nicaragua, Momotombo  has had a number of explosive events over the past week, prompting René Goad to ask on our Facebook Page “Is it me or has the crater on Momotombo got larger?”

To which Alex Bogár posted this image taken a few days earlier and he also said “A small part collapsed too from the other rim, that’s why the pdc was so brownish colored”

Also in Nicaragua, the Telica volcano had a number of explosions on the 13th, with Ineter reporting “12 small explosions” according to Volcano Discovery


In Guatemala, Washington VAAC reports that Santa Maria is continuing to produce plumes up to 15,000 feet with activity reported on most of the days of last week.


South America

Only a couple of reports from South America with the Washington VAAC and the Buenos Aires VAAC reporting activity at Reventador and Sabancaya respectivley.  Both reports state that plume was visible on webcam on the 15th for Reventador and the 13th and 15th for Sabancanya, but at the time of writing I was unable to find images from the dates in question.


At Copahue, the Buenos Aires reports a continuos emission of gases and steam and the occasional burst of volcanic ash.



This concludes my round up of the activity of the last weeks activity, did I miss anything??

  1. Thanks for the update! Did you miss anything? Maybe a huge pillow of magma gently massaging Iceland from below 😉

    Jokes aside, great post, again.

  2. Great post again! The active list is now so enormous that you might call it a Leviathan. Jokes apart, are those the rooftops of Petropavlovsk in the foreground of the Zhupanovsky photo? GVP says population within 30km – 153, population within 100km – 267,080, and that AFAIK is the only large popiulation centre in Kamchatka

    • Vladivostok (pop. 592,034 as of the 2010 census)? It’s in the shadow of two large stratovolcanoes, Avachinsky and Koryaksky, and partly built on a debris avalanche from the former. It also featured in the first lead-up article to the NDVP:

    • The photographer’s profile days they are from Petropavlovsk, so that would be a good guess

      • “In order to gain access to the area, Keow had to beat tight security.”

        Run this past me once again, please. Why do I get the impression that this clearly intellectually challenged individual is lauded as a hero for his stupidity.

      • From the looks of things-she could handle herself.
        My Pop and Uncle all taught the McCoy girls how to
        throw a punch and fight ah, unfairly…
        Saved one of the cousins from being beaten by an
        ex-husband. She beat him to a pulp

        Edit add:→ BRAVO ZULU

      • It appears that he was behind her right shoulder when it got nasty. Dunno what he was trying to do, but she evidently did not approve. As your vet said about the squirrel, “He probably had it coming.”

        No matter what the legality of it is, if you are attacked, an overwhelming response will tend to make the attacker reconsider the action next time.

        The other half is violence.

    • Hobbes, thanks again for the weekly summary which clearly takes lots of hard work and time.

      Regarding surfing on volcanoes, I note our experience with this subject. A couple of years ago we stayed in a hostel in Leon, Nicaragua. The hostel and clients were pleasant and generally well behaved. Leon is very hot and humid and the hostel had a swimming pool. A bunch of gringos from el Norte started jumping in to the pool, not allowed, causing a minor disruption. They were talking, loudly, about a young Swedish girl who had broken a leg during a surfing session and then about another person who was injured during volcano surfing.

      I have a tendency to just start talking to people met during our travels and there was a young man having coffee who appeared to have a broken arm and his face was deeply scratched with embedded, fine volcanic ash. He explained how he was injured and how dangerous the sport was using these crude improvised boards provided by the “sporting center”. The boards were essentially uncontrollable and they went down the very steep slope IN THE DARK. He just kept shaking his head and muttering, I could have broken my neck, I could have broken my neck. Well it would seem that his testosterone high was soon replaced by an adrenaline rush and finally a spurt of a lesson well learned. He was lucky to survive. The Daily Fail story take the insanity one magnitude higher.

      • An application of Lurking’s ‘Homo Stultus’ phenomenon; the inability to comprehend that while fine volcanic ash may LOOK like dirty snow, its properties are rather different – especially when human flesh impacts it at high speed.

    • Do you have a source?? I haven’t seen this anywhere… *runs to check Tokyo VAAC*

      • Nice! It’s definitely one for Mastermind:

        Magnus Magnusson: Recently Aso volcano erupted at 1.49 m³/s DRE rate. For how long would it have to maintain this rate of eruption if it was to reach VEI 8?

        Contestant: Erm… 21,352 years?

        Magnus Magnusson: Correct.

        • Thomas, the year is 365.25 days long and then there’s a leap second every millennium or so (which I think we are entitled to ignore). 😉

          • 365.2422 days, to be precise. Leap seconds happen every 2 year or so but don’t affect either the length of the year or the lengths of the second so can be ignored.

      • @ Hobbes – sorry forgot to mention the source. It was Tokyo VAAC. Anyway, I really enjoy being up to date for once thanks to your list – thank you for all the effort!

        Haha Lurking you made me laugh 😀

  3. I was wondering which volcanoes are capable of doing a big supervolcano eruptions. I am studying it, and except for yellowstone, it isn’t easy to find information about it on the internet (because everyone exaggerates it, or you can’t simply find correct information. For a VEI 8-eruption: i only know Tondano, Toba, Taupo and Yellowstone are capable of produce such an eruption. Maybe there are others, but i don’t know them.

    For a VEI 7-eruption, i have this.

    Aira Caldera – Sakurajima
    Altiplano-Puna complex – Uturuncu
    Taupo Complex – Nieuw-Zeeland
    Toba Complex, Indonesie
    Campi Flegrei
    Long Valley Caldera
    Valles Caldera (extinct or dormant?)
    Mount Aso (not sure?)
    Reporoa Caldera
    Kikai Caldera
    Mount Tambora
    Baekdu Mountain
    Laacher See (not sure about this, is also pretty hyped, read something about people that suggested it was actually a VEI 6 (something like Vesuvius. This volcano is also non-active.
    Laguna del Maulle
    Cerro Negro Volcanic Complex
    Mount Mazoma, Crater Lake
    Kurile Lake
    Mount Tondano
    Rabaul Caldera
    Macauley Island?

    I miss probably a lot of volcanoes in Mexico, Nicaragua, Africa, China (?), and Papua-New Guinea/Indonesia. Do others have some volcanoes that are capable of a great eruption, but are not in the list?

    Thank you.

    • Long Valley Caldera and Atitlan are still active and have produced VEI-8 eruptions, but that would pretty much it.

    • Volcanoes that have had recent large eruptions are unlikely to produce something big now. And a very large eruption in the distant past makes a recurrence also less likely: Toba, Yellowstone, have activity but no indication of any impending VEI7. You need dormancy of 500 years, up to a few thousand years (others will disagree with the exact numbers). In the US, that is the case for the Southern Sister (Oregon), Adams, Newberry and Medicine Lake (California). However, predicting how large an eruption may be from these is difficult: for instance, Newberry is less likely to produce a major eruption. In your list, Taupo may be possible. The ones to be aware off are the one you didn’t know were volcanic.

  4. What about Chacana as possible 1809 missing link (if it is not Reventador in Ecuador). Could something be missed?

  5. I see there has been a 2.9 at only 600m deep at Bardabunga in the last hour.

  6. There has been a 5.1 earthquake in the Sea of Alboran today and Spain is getting twitchy that no-one is monitoring the volcanic island nearby that is off the coast of Algeria.

    • Well, they can get twitchy all they want. Just send Nemesio Perez.

    • The problem is not the volcanism, the problem is the earthquakes. If that little hillock suffers a mass waste in the middle of Homo Stultus Beach Week of Ibiza (this Lurking is about as bizar as Spring Break) a lot of people would die.

        • Well, at least it could be worse…
          You could have been going to St Tropez during the Swedish Week.
          It has been called “Europes Largest Natural Catastrophy” by the French Gendarmerie.

      • I’m not familiar with the island… but I have witnessed the all too familiar beach festivities in Palma de Mallorca.

        The biggest issue we have had of late in Panama City, are the ones who get tangled up on the hotels while doing towed paragliding. It’s such an issue, that the State of Florida has enacted new safety regulations for the activity. Can’t have the errant Sultii dangling by shroud lines off the side of a hotel ya know. Bikinis are not suitable safety gear.

        Personally, I really detest the traffic of Spring Break. However, I did get to sit stuck in traffic down on Hwy 98 behind a convertible full of a group of college age girls on the way to the beach. They were having a horrible time of it. The traffic had come to a standstill in the aromatic plume of a ruptured septic line somewhere upwind. They were NOT having a good day of it… provided that they were not too drunk to notice.

        From last year: Florida church with naked paint parties loses tax-exempt status

        They claimed that it was part of their Youth Outreach program. To me, it seemed more like a bottle club type of organization. In standard bottle clubs, you deposit your previously purchased liquor with the bartender and when you want a drink, you buy the set-up for your drink, using the alcohol from your bottle. That avoids the legally mandated last call for liquor sales. The one I used to frequent typically closed around daybreak.

        The cool bit is when you meet a girl who is in need of a drink and she asks if she can have one made from your bottle.
