    We All Nearly Missed The Largest Underwater Volcano Eruption Ever Recorded

    We All Nearly Missed The Largest Underwater Volcano Eruption Ever Recorded (ARTICLE LINK)


    Excerpt
    She was flying home from a holiday in Samoa when she saw it through the airplane window: a "peculiar large mass" floating on the ocean, hundreds of kilometres off the north coast of New Zealand.

    The Kiwi passenger emailed photos of the strange ocean slick to scientists, who realised what it was – a raft of floating rock spewed from an underwater volcano, produced in the largest eruption of its kind ever recorded.

    "We knew it was a large-scale eruption, approximately equivalent to the biggest eruption we've seen on land in the 20th Century," says volcanologist Rebecca Carey from the University of Tasmania, who's co-led the first close-up investigation of the historic 2012 eruption.

    The incident, produced by a submarine volcano called the Havre Seamount, initially went unnoticed by scientists, but the floating rock platform it generated was harder to miss.

    Hope the voyage is a long one.
    May there be many a summer morning when,
    with what pleasure, what joy,
    you come into harbors seen for the first time...

    If there's a new island, who does it belong to?
    Do not speak of "our institutions" unless you make them yours by acting on their behalf.

      No seismometers picked it up?
      Structures without reference to geometry tend toward the ramshackle

        So much data, so little time....

        That’s politicians. Different game entirely.”

          I seem to recall some posts about it (on here?)... of yachts striking it - edit - here's the photo of this one, I may be remembering the Tongan one from 2006



          Havre Seamount has a caldera capping a 1-km-high edifice. Located on the Kermadec Ridge, it is believed to have erupted in July 2012, the first recorded activity. The caldera has an asymmetric morphology with the N rim comprising mostly a single inner topographic wall, and the S rim comprising both an outer topographic rim and inner wall separated by a 1.1-1.4 km wide terrace. Smaller craters occur on this terrace. Rocks from the caldera wall include aphyric and plagioclase-bearing basalt-andesite, aphyric and plagioclase- and pyroxene-bearing dacite, gabbro, diorite, and pumice (Wright et al., 2006).
