Worrying: ‘Child of Krakatau’ volcano stirs to life in the Pacific

From the “this can’t be good” department and AFP:

An Indonesian volcano known as the “child” of the legendary Krakatoa erupted on Thursday, spewing a plume of ash high into the sky as molten lava streamed down from its summit.

No one lives on Krakatau, which forms a small island in the Sunda Strait between Java and Sumatra, but the peak is a popular tourist spot.

Indonesia’s geological agency has not raised the alert level for the mountain. However, there is a one kilometre no-go zone around its summit.

When Krakatoa erupted in the 19th century, a jet of ash, stones and smoke shot more than 20 kilometres (12 miles) into the sky, plunging the region into darkness, and sparking a huge tsunami that was felt around the world.

The disaster killed more than 36,000 people.

Anak Krakatau has rumbled back to life in recent weeks, spitting flaming rocks and ash from its crater

Indonesia is situated on the Pacific “Ring of Fire”, a vast zone of geological instability where the collision of  causes frequent quakes and major volcanic activity.

    • A big volcano can cool things off a lot. It’s called volcanic winter. We have recent data, which is bad enough, but there is evidence that prehistoric eruptions killed a large segment of life on Earth.

      • I’m sorry, but Al Gorge told me that CO2 causes volcanoes. If you cant believe Big Al (who is growing bigger all the time) who can you believe?

      • Yes Toba was a caldera forming super volcano on Sumatra that nearly wipe out all humans 70,000 years ago. Rumor has it that this was when the wheel was first invented, and humans were working on a proto-SUV. This pissed off Gia and she nearly wiped out the entire species. After the Toba event, it took another 65,000 years until the wheel was re-invented.

        I swear, that at least some of the above, is true.

      • More violent than Krakatau and the largest recorded in the region was Tambora in 1815. Seems to me a pretty good argument can be made that the effects of the LIA were extended by a series of significant eruptions near the equator in the early 19th century. That would included “the year without a summer” in 1816 in the US which it seems almost certainly resulted from the Tambora eruption.

        BTW Anak Krakatoa raised right up out of the huge collapsed caldera of it’s parent and has been erupting and growing since 1927. It would seem to me that we here will be long gone before it will grow up to be the destructive monster of it’s forbearer.

          • A heck of a lot better than what happened before. Personally it wouldn’t matter for me. Though I served for 8 years on my county’s cemetery commission identifying and rebuilding pioneer grave yards and recognize the historic, genealogical, and sentimental values of such places. I really don’t care for being part of one myself. So I’ll be ashes anyway.

    • Its gotta be due to the collapse of the Antarctic ice sheets causing the Pacific plate to tilt and allow this volcano to vent…..
      “yeah …that’s the ticket!”

      • I’m more worried about it becoming unhooked….it could float into some big seaport or city

        • If it came Unhooked, It could Flip Over (reaching the Volcanic Tipping Point) and boil the oceans away

          • Did that Democrat pass grade 1 exams? Perhaps he should have started school in prekindergarten to give himself a head start. Grade 1 geography, I guess was too advanced for him.

          • Australia could slam into it first, it’s in a mobile belt after all.

            Scale and continental roots be damned!–ramming speed!

          • Graeme,
            You might have a point.
            I came across this a few years ago: –

            AUSTRALIA GETS DRUNK, WAKES UP IN NORTH ATLANTIC

            Tired of Being Isolated and Ignored, Continent Isn’t Bloody Moving

            Sydney, 800 miles S. of Nova Scotia (SatireWire.com.bah) After what witnesses described as an all night absolute blinder during which it kept droning on about how it was always being bloody ignored by the whole bloody world and would bloody well stand to do something about it, Australia this morning woke up to find itself in the middle of the North Atlantic.
            “Good Lord, that was a booze up,” said a bleary-eyed Australian Prime Minister, speaking from his residence at Kirribilli House, approximately 600 nautical miles east of Cape Hatteras, North Carolina.
            According to Australians and residents of several countries destroyed or lewdly insulted during the continent’s nearly 17,000-mile saltwater stagger, the binge began just after noon yesterday at a pub in Brisbane, where several patrons were discussing Australia Day (Jan. 26) and the nation’s general lack of respect from abroad.
            “It started off same as always; coupla fossils saying how our Banjo Patterson was a better poet than Walt Whitman, how Con the Fruiterer is funnier than Seinfeld, only they’re Aussies so no one knows about ’em,” recalled witness Kevin Porter. “Then this bloke Martin pipes up and says Australia’s main problem is that it’s stuck in Australia, and everybody says ‘Too right!’ “Well, it made sense at the time,” Porter added.
            By 2 a.m., powered by national pride and alcohol, the 3-million-square-mile land mass was barging eastward through the Coral Sea and crossing into the central Pacific, leaving a trail of beer cans and Chinese take-away in its wake.
            When dawn broke over the Northern Hemisphere, the continent suddenly found itself, not only upside down, but smack in the middle of the Atlantic, and according to most of its 23 million inhabitants, that’s the way it’s going to stay.
            “We sent troops to Afghanistan. You never hear about it. We have huge government scandals. You never hear about it. It’s all ‘America did this,’ and ‘Europe says that,'” exclaimed Perth resident Paul Watson. “Well, we’re right in the thick of things now, so let’s just see if you can you ignore us.”
            Officials on both sides of the Atlantic conceded that would be difficult. “They broke Florida,” said U.S. State Department spokesman Richard Boucher. “And most of Latin America is missing.”
            Meanwhile, victims of what’s already been dubbed the “Australian Crawl” are still shaking off the event.
            “Australia bumped into us at about midnight local time,” said Hawaii Governor Ige. “They were very friendly – they always seem friendly – but they refused to go around unless we answered their questions. But the questions were impossible. ‘Who is Ian Thorpe? Do you have any Tim Tams? What day is Australia Day?'”
            “Fortunately, somebody here had an Unimportant World Dates calendar and we aced the last one,” Ige added.
            Panama, however, was not so lucky.
            “Australia came through here screaming curses at us to let them through,” said Ernesto Carnal, who guards the locks at the entrance to the Panama Canal.
            “We said they would not fit, so they demanded to speak with a manager. When I go to find Mr. Caballos, they sneak the whole damn continent through.”
            When Caballos shouted to the fleeing country that it had not paid, Australia “accidentally” backed up and took out every nation in the region, as well as the northern third of Venezuela. They then made up a cheery song about it – not all the words began with B – or F!
            By late morning today, however, not everyone in Australia was quite so blithe. “We’ve still got part of Jamaica stuck to Queensland,” said Australian army commander Lt. Gen. Peter Cosgrove. “I think we might have declared war on it. I don’t bloody remember. Maybe it’s time to go home.”
            Cosgrove, however, is not in the majority, and at press time, U.S., African, and European leaders were still desperately trying to negotiate for Australia’s withdrawal.

            But the independent-minded Aussies were not making it easy.
            In a two-hour meeting, beginning at midday (old) Canberra time, Australian representatives listed their demands: –
            immediate inclusion in the North Atlantic Treaty Organization; Protected Origin rights for Vegemite;
            a permanent CNN presence in all 6 Australian states;
            a worldwide ban on hiring – or even mentioning – Paul Hogan;
            a primetime U.S. television contract for Australian Rules Football;
            Tim-Tams to be available in all US Shopping Malls;
            recognition of the platypus as State Animal for Queensland;
            and a 5,500-mile-long bridge between Sydney and Los Angeles.

            U.S. negotiators immediately walked out, calling the Australian Rules Football request “absolutely absurd.”

            Auto – with an utterly straight face.

          • And this dumbass /Vigger is a congress critter? God help us! No wonder we are sinking as a nation!

        • Its worse than that. The increasing CO2 is worming its way into the open holes in the volcano and then causing even greater eruptions. Don’t ya know; CO2 is so baddddddddddddd it even causes volcanos to be worse. Baaaaaaaaaaaaaaaaad Co2 Badddddddddddddddddd

      • That was my exact thought, Bryan. Alarmists breathing a great sigh of relief. Now if temperatures drop, it is all explained. And if they rise, then it is unprecedented proof of CAGW.

    • The heat deep in the oceans when SO deep it went into the mantle and is escaping via this volcano!

      The Power of CO2 Cannot Be Stopped!

    • This is caused by overpopulation by humans. They all weigh too much and that extra weight is increasing the pressure and forcing the tectonic plates to be more active

    • Patrick !
      Gaia STRIKES BACK !
      The END IS NIGH !
      I’m in the process of writing a book , applying for a study grant and would
      appreciate your support !
      signed : F.O.Shortly.
      Tom in Denver :
      You are correct….except that they built it square , put the spokes in it , then stuck
      it in a hole in the wall and called it a window ! What a missed opportunity that was !
      sarcasm in case no one noticed !

  1. Well, if it’s erupting, maybe the pressure won’t build up as drastically as when the volcano is silent.

    • Lots of little ones to relive the stress instead of one big one? I’m okay with that. Here’s hoping that’s how it works 🙂

    • This eruption is not unusual. Anak Krakatau is one of the most active volcanoes on earth. It has grown at an average rate of five inches (13 cm) per week since the 1950s. This equates to an average growth of 6.8 meters per year. The island is still active, with its most recent eruptive episode having begun in 1994. Quiet periods of a few days have alternated with almost continuous Strombolian eruptions since then. (https://en.wikipedia.org/wiki/Krakatoa#Anak_Krakatau)

      • Five inches per week? That is almost as fast as the sea level rise that is going to short out the Internet.

      • Only 5 inches per week? Why hasn’t sea level rise overrun and drowned it out like an old campfire?

    • You can actually rent a boat and get relatively close to Anak Krakatau.
      Back in the late seventies when I worked in Sumatera you could rent a boat and get right up too at the time much smaller Anak. The more foolhardy could actually land.
      There were two young boys on the boat I went out in. Their specific job was to watch for lava bombs.
      The authorities sort of frown on this now. And it’s now much harder to find someone with a boat who will get you on land.

  2. A bunch of Volcanoes are spewing worldwide..
    Here is one..
    A powerful eruption at Vanuatu’s Ambae (Aoba) volcano at 03:30 UTC on July 16, 2018 has ejected ash up to 9.1 km (33 000 feet) above sea level.

    Off the back of the 6.4M Vanuatu earthquake, July 13th, comes a strong eruption from this potentially deadly volcano.

    Ambae’s April 5th 2018 eruption, entirely under-reported by the mainstream media, emitted the most sulfur dioxide of any eruption since Calbuco, Chile in 2015.
    https://electroverse.net/ambae-aoba-volcano-spews-ash-9-1-km-30-000-feet-vanuatu/
    Here is a worldwide map.
    https://earthquakes.volcanodiscovery.com/

    • Climate-wise, Calbuco was a non-event
      https://wattsupwiththat.com/2015/10/06/recent-lunar-eclipse-reveals-a-sign-of-global-cooling-in-the-atmosphere/
      or
      http://spaceweather.com/archive.php?view=1&day=08&month=10&year=2015
      and I’d expect Ambae to be even less of a climate event.
      I.e., not detectable.
      However, Susan Solomon and other IPCC types are convinced that these volcanic blips are the Cause of the Pause, but they deny that the much, much larger events like Pinatubo are responsible for much of the earlier warming (in the 1990s, causing relative warming by cooling previous years).

      • Amazing how they always have it both ways – volcanoes DO cause cooling when they can’t explain a lack of warming away in the face of rising CO2, but DON’T cause cooling when their eruption precedes a warming period that provides them with the veneer of supposedly “CO2 induced” warming.

        • Amazing indeed – especially when the DON’T volcanoes are 20x larger than the DO volcanoes!
          I’ve always been amused by the attempts of the warmers to explain away the obvious with creative hypotheses.

        • I was just thinking, maybe volcanoes are caused by plumes of volcanic ash in the troposphere. Just like temperature rises are caused by increasing CO2 concentration and sunrises are caused by roosters crowing. Think about it, there is a nearly perfect correlation between volcanic ash in the atmosphere and the incidence of volcanic eruptions. That’s it, the science is settled. Can I get some peer review?

          • Volcano sex. One advertises for a mate by a long, slow eruption over decades. Then the male volcanoes explode violently in response. Isn’t that obvious??

          • Rich, you’ll have to make a computer model for that and submit it’s results before they can be taken into full account, with at least ten years of forward projections.

            No need for Peer review, no Peers in America, they’re not allowed by law. But your logic is impeccable and suitably sciency to pass the threshold of the 97%ers.

        • But that’s the strength of climate science! Whatever the observed facts may be, they always lead to the same conclusion! No more sleepless nights pondering what your data means! The answer is ready for you, fully formed! What a gift to humanity!

    • And a large crack opened in Grand Teton National Park, which is on top of the Yellowstone caldera.

  3. The “Anak’ Krakatau, like any petulant “anak”, acts up frequently. I lived near it for most of the 1990’s. Every time I had a trip lined up to go visit the site it would spew some lava bombs and it would be closed to boats for awhile.

    When the big one blew, the shockwave made a full lap around the globe.

    • “the shockwave made a full lap around the globe”
      I’ve read the shockwave went around the globe as many as 4 times, as apparently measured by various barometers around the world.

      • I have just finished reading Simon Winchesteer’s book: “Krakatoa:The Day the Earth Exploded, August 27, 1883”. He says the pressure wave from the explosion circled the Earth seven(!) times as recorded on barographs.

  4. In Scottish Gaelic the word for child is “aonach” –
    pronounced “anak”. Coincidence?

  5. Has anyone looked at the stats of active eruptions around the world across time? It might not be a random walk.

    • I got interested in that during the last big eruption in Iceland. There was a correlation with larger eruptions and gsm’s/Gleissberg cycles. I mentioned this on an Icelandic site which had extensive coverage of that long lasting eruption, and several bloggers stated that they were aware of the connection.

      • Some speculate that silica rich volcanoes go off during solar min due to increased cosmic rays. Cosmic ray levels are currently very high. Also of note is the neutron count during a major eruption.

      • Novice here. What impact do the large gas planets have on earth? They can alter the position of the sun, so why not have an impact on plate tectonics?

    • The increase in volcanic activity is likely a delayed response to the increased extruded liquid CH4 from the core of the planet. As noted below, observations support the assertion that there is liquid CH4 in the liquid core of the planet.

      The liquid CH4 is extruded from the liquid core when it solidifies. The liquid core of the planet started to solidify roughly a billion years ago. The liquid CH4 that is extruded from the core of the planet is the force that drives tectonic plate movement and provides the hydrogen that explains why 70% of the earth is covered in water.

      There was been an unexplained 200% increase in mid-ocean seismic activity period B for the entire planet as compared to period A. The changes in mid-ocean seismic activity highly correlated with the temperature changes in the period.

      Prior to the observation that the mid-ocean earthquakes increased by 200%, the standard belief was that it is not physically possible for the frequency of earthquakes to increase by 200% for a long-term period.

      It was believed that earthquake occurrence was/should be statistical (random, chaos).

      Based on the fact there are no geological smechanisms that could suddenly change to increase heating in the earth.

      And even if there was a mechanism to increase heating in the earth: the heating would be regional, not for the whole earth.

      And lastly even if there was a means to increase heating of the earth, heating changes to the earth due to the mass of the earth, would be very, very slow and changes would occur over long periods of time, not a ramp up of two years.

      The earth’s mid-seismic activity has abruptly dropped back down to the lower activity in period B.

      Period A: 1979 to 1995

      Period B :1996 to 2016 (More than 200% increase in mid-ocean seismic activity)

      The observed changes in mid-ocean seismic activity are orders of magnitude too large and too fast for all of the current geological mechanisms to explain.

      The assumed energy input for the mantel and core (radioactivity, material phase change, reactions) cannot physically change in that time scale/entire planet and even if they did change could not appreciably change temperatures to affect mid-ocean seismic activity for the entire planet.

      It is physical impossible for the current standard geological model (and its assumptions) to explain the sudden and astonishingly large increase and decrease in mid-ocean seismic activity.

      As noted in the paper below, increase in mid-ocean seismic activity closely correlates with ocean temperature changes for the entire period.

      https://www.omicsonline.org/open-access/have-global-temperatures-reached-a-tipping-point-2573-458X-1000149.pdf

      Two previous studies, The Correlation of Seismic Activity and Recent Global Warming (CSARGW) and the Correlation of Seismic Activity and Recent Global Warming: 2016 Update (CSARGW16), documented a high correlation between mid-ocean seismic activity and
      global temperatures from 1979 to 2016 [1,2]. As detailed in those studies, increasing seismic activity in these submarine volcanic complexes is a proxy indicator of heightened underwater geothermal flux, a forcing mechanism that destabilizes the overlying water column.

      This forcing accelerates the thermohaline circulation while enhancing thermobaric convection [3-6]. This, in turn, results in increased heat transport into the Arctic (i.e., the “Arctic Amplification”), a prominent feature of earth’s recent warming [7-9]. .

      …there is a 95% probability that global temperatures in 2019 will decline by 0.47°C ± 0.21°C from their 2016 peak. In other words, there is a 95% probability that 2019 temperatures will drop to levels not seen since the mid-1990s.

  6. I dare say Piers Corbyn will look on increasing vulcanicity as entirely predictable.

  7. Oh man Guam better shore up. If this thing blows the resulting tsunami might just flip it over like a pancake!

    • Forget Guam! What about poor Tuvalu? If a “Super Moon” could take it out, what would a tsunami do to it?
      (Tuvalu must have been a lot higher in the 19th century.)

  8. Let us hope that no / not too many lives will be lost when it is getting really hot there. May be a prayer will help, or at least give some consolation.

    • And how much tax will Indonesia pay when the beast spews the equivalent of all the CO2 emitted by mankind. Environmentalists might just get the dark ages they have been lobbying for if this thing really blows.

    • The max temps in the tropics are not increasing. Most of the worldwide increases are in the min temps in the higher latitudes, so relax, there’s no planetary emergency.

    • “May be a prayer will help, or at least give some consolation.”

      Might make you feel better about yourself, but beyond that, nada.

  9. One or two or three, more than usual ….
    + long, possibly minor Grand (contradiction in terms) solar minimum
    Are the two big bully boys J & S hassle the solar system again, as they may have often done before /sarc

    • Anyone remember the old 1969 disaster movie “Krakatoa, East of Java”? All good except for the small point that Krakatoa (as it was then called) is west of Java.

      • In the movie the eruption looked like a dozen sparklers, a bit underwhelming. Especially since I was in the Army at the time, playing with real boomers.
        But the movie was worth a couple of beers at our outdoor theatre.

    • When the great cooling comes and we are thrown back onto stone age technologies, we will have ceremonies at the caldera of volcanoes and throw in wind turbines.
      So yeah, actually they are recyclable.

  10. Earth’s magnetic poles are reversing. Iron in the magma is being pulled in new corculation patterns.

    • My Silva hillwalking compass needle seems to point the wrong way now. The last time I used it it was fine. Now the N end points south. Couldn’t possibly be that I just messed it up by leaving it next to a magnet now could it? Still “works” but you need to remember that it’s 180 degrees out.

    • Thanks for the reminder. I need to get a new compass. Next time I go to Bass Pro, I will see if they still have them. Maps and compasses, much better than GPESSes

      I’m wondering (because I don’t recall anyone, including volcanologists, ever addressing it before) how much volcanic activity preceded magnetic pole swaps, and how much occurred shortly afterwards. There was a long period of frequent polar swaps before the last one (740,000 years ago), and hasn’t been one since.

      Just wondering, that’s all.

  11. One more excuse for models to fail and the end of times to be delayed til the next grant cycle.

    • ummm… not quite, the four blasts on the morning of the 27th most likely ruptured the magma chamber allowing seawater to contact the hot magma. The resulting explosions known as phreatomagmatic events literally blasted the island apart leaving a caldera below where the island used to be. The last eruption at 10:02am blasted an estimated 11 cu mi of debris into the atmosphere. Anak Krakatau first poked its head above the surface of the sea in 1927. It is still growing.

  12. At most, one or two years of cooling. These occasional Indonesian burps do little damage. The big ones, a hundred times larger, are the worrying ones.

  13. All of what you see in the picture is new, less than 100 years old, and more is going on subsea that you can’t see. The growth rate of volcanoes like these is phenomenal.
    Krakatoa has erupted bigtime every few hundred years. We’re about due for a big one – that’s not a prediction for this year BTW – but it will happen again and we’re (probably) closer to the next than the last.
    My concern is mainly for Jakarta and its 10 million inhabitants as they’re only 100 km away

  14. Ring of Fire I can accept but Pacific is a bridge too far.
    Last time I looked if you head south out of the Sunda Strait you find yourself in the Indian Ocean.

  15. Um, Krakatoa, and indeed Anak Krakatoa, are not in the Pacific Ocean. More like between the Java Sea and the Indian Ocean, lying as they do in the straits between Sumatra and Java.

  16. Wait! Let me guess; this volcano is due to “climate change” from SUV’s, capitalism, guns & racism & we need to create a new global bureaucracy run by power hungry drunks to tax us who are unaccountable to voters?

  17. Anak Krakatau is a very active volcano. From http://volcano.si.edu/volcano.cfm?vn=262000 . . . .
