Why does the Hawaii Kilauea volcano keep erupting?

  • Published on May 10, 2018
  • Hawaii's Kilauea volcano could soon send boulders and ash shooting out of its summit crater in the kind of explosive eruption last displayed nearly a century ago. CBC science commentator Bob McDonald explains why Kilauea has been continually erupting for centuries and how it compares to other volcanoes.

    Ouch...no water? Um...ocean? Water table? Hmmm...the lava in the volcano has dropped and yes there could be water that gets to it from tubes made by the volcano itself centuries ago/decades ago. It is a danger. It may not ever happen but you can't say it won't happen. It's not likely to hurt anyone because it's in a National Park area (thank goodness for national parks).

    The Pacific plate is moving at just 7 cm per year. In a thousand years that's less than the length of a football field. I think Bob's estimate of "a couple thousand years" may be a bit optimistic. :-)

    Serious question. In the area that has been destroyed or covered in magma; do they rebuild on top of it, remove the product when it dries or hardens, or do they just permanently abandon the area and let mother nature take over?

    Explain the 1000 earthquakes on 1 spot of the islands he said theres no water to create steam to cause an explosion... BS Hawaii is has water under the ground but theres GYOTHERMAL that's shooting tons of water to create fissures to create steam to collect for energy.. tell the truth

    • Maui Randall
      Maui Randall 4 days ago

      Half time Sione over what period of time was the 1000 earthquakes cuz most earthquakes aren't very noticeable especially the people who are very close to the volcano
      And the water used for geothermal isn't nearly on the same level as say the Saint Helens eruption

    Mts. Vesuvius and St, Helens are Plinean volcanoes. These volcanoes also have pyroclastic flows. Yellowstone Volcano is a caldera and a Plinean type volcano; Plinean because when it eventually goes will have pyroclastic flows.

    Is CBS News not based in the United States ? When did we officially convert to measuring things in kilograms and kilometers ?? Can you translate that into feet and miles , some of us are still just American, not globalists.

    • Zeuszgrl
      Zeuszgrl 4 days ago

      Fact of the matter is, metric is *not* the standard means of measurement in the U.S., has nothing to with laziness tard. Go find an argument worthy of debate instead of disputing facts.

    • Maui Randall
      Maui Randall 4 days ago

      PS even if it was converted to feet I doubt you'd be able to convert it to miles without looking it up even though they're the same *American* system, because it's a dumb system, even if I gave you the number of feet and the conversion of feet to miles you'd still probably have to break out a calculator, which you wouldn't have to do if it was a base 10 system

    • Maui Randall

      And by the way what's wrong with a global measuring system what's wrong with trying to limit the amount of confusion between countries what's wrong with the metric system cuz I can give you a million things that are wrong with the system that we're forced to use

    I said this was going to continue over a week ago. It is a Grand Solar Minimum.
    #1 Increase Volcanic Activity
    #2 Increased Earthquake Activity
    #3 Increased Clouds
    #4 Drop in cold temperatures in the same locations as the Great Ice Age 45,000 year ago
    #5 Rising Temperatures in the exact same places as the Severe Droughts in the last Ice Age 45,000 years ago
    #6 Ocean rise will slow and then stop.
    #7 As the ice sheets start to rebuild, the oceans will start lowering.
    The earth is still in the effects of the last ice age. The inter-glacial cycle ended around 1999-2000 and is going back into a glacial period.
    Every return to an ice age, is marked by increased Volcanic and Earthquake activity.
    Did you know that some of the record cold temperatures and snow fall that were set in 1924, were matched or broken here in the North East USA during this winter cycle. What happened in Hawaii in 1924? Bing Go! It was a Solar Minimum, but it was a Solar Minimum in a warming cycle. This is a Solar Minimum in a cooling cycle.

    74,000 or so years ago a volcanic eruption/explosion, Mt. Toba, took mankind down to just a few thousand people. That's why our DNA is so close to each other. Screws up that whole looking for the Mitochondrial Eve nonsense we heard about in the early 90s.
