    Default Tsunami Warning fom Tonga

    This in late....well, for me anyway.

    The fact that there's a highway to hell and a stairway to heaven says a lot about the anticipated traffic flow.

    Imagine what something like Karakatoa looked like.

    Isn't it just, absolutely astounding ~ redefines one's tacit understanding of just how big a boom, a volcanic explosion can be.

    Indeed, Krakatoa ...for years and years since a kid, hearing about, seeing/reading reports of how big that blast was, I've never until now seeing the above vid, been able to appreciate how big Krakatoa must of been...

    ...like, they say the blast/shock wave of Krakatoa "pressure wave was recorded on barographs all over the world. Several barographs recorded the wave seven times over the course of five days: four times with the wave travelling away from the volcano to its antipodal point, and three times travelling back to the volcano" ....and you think 'wow' for decades never being able to really grasp how big that pressure wave was.

    Then you see this, and your brain goes 'Ahh!...-that- pressure wave, holymumblefuk'...this is tiny compared to what Krakatoa produced wrt pressure/shock wave 8).

    A nightmare for the greens.
    Explain how humans cause more pollution than this.
    Oh wait! This was caused by man made pollution. Silly me.

    Abso bluddy lootley fantastic. Again, it makes me think how lucky we are to be in Australia. I feel for those on the pacific rim without the likes of the Barrier Reef to mitigate the effects of the tidal surge. Any news from Tonga and other nearby islands yet?

    Communications links with Tonga were almost totally severed by the eruption and tsunami, so details of the impacts are still sparse. What's clear is that the Tongan people are asking for solidarity — not victimhood and erasure.

    At work but I just wanted to reach out, I know a lot of you are concerned about family here in Tonga, thankfully we have no reported casualties. We have very limited contact with the outside world.

    Pretty cool to see it as a satellite image.

    But when it comes to size, this was a little one compared to Krakatoa which was about eight times bigger.
    Tonga has a VEI of about 5. Krakatoa was a 6 something. (the scale is orders of magnitude 10^vei)

    But don't forget there were some other big ones recently. Mt St Helens in the USA was also a 5.
    Mt Pinatubo is the winner in recent times with a VEI of 6. It messed up a lot of shit. Flying over it, wow, it's a monster.

    But just down the road from Krakatoa is Mt Tambora. This firecracker was the largest volcano in recorded human history with a VEI of 7.

    And if you think that one was big about 1000 years ago, the Taupo Eruption in NZ about 1500 years ago was also a VEI of 7.
    Lucky for the Maori they arrived about 500 years later.

    But the biggest that (early) humans have experienced was Lake Toba. That was pherking collossal with a VEI of 8.
    Hard to imagine something 100 times bigger than Krakatoa and ~1000 bigger than Tonga. It wiped out a lot of species.

    And these are single big events. There were some frickin amazing forms of volcanism that are not one specific event, long before humans were around. The Decan Traps, the Siberian Traps, the usual Super Caldera volcanoes like Yellowstone, which is not even the most nasty customer about to come calling in the next few million years. I think that one goes to the Caldera in the Bay of Naples.

    The kind of Eruption I'd like to see is a Kimberlite type. I reckon they would be one of the most spectacular types of Volcano.

    And while Australia doesn't currently have any active volcanoes, Victoria and South Australia do have dormant volcanoes.
    The youngest Australian volcanoes don't throw out a lot of lava and ash. They're more steam volcanoes. Kind of like geysers that take a few thousand years to recharge. Mt Gambier and Colac region are the youngest. But don't hold ya breath on them reactivating in a human lifetime.

    Certainly a big bang , though another one close to Oz is the volcano in Rabaul , PNG. I think in 1999 the top 2 thirds of it was blown off , totally destroying the " Jewel of the South Pacific " . One surviving building is now the museum and you can do a walking tour to the base. Still a lot of smelly sulfuric vapours present and the water is still Orange. Worst part was that the increase in water temps and the prevailing ocean currents have destroyed coral growth down as far as Townsville.
