As scientists continue to pour over the data from this year's lava flow, more statistics are beginning to emerge. The most striking - - that this was the biggest lava event in Hawaii in two centuries:
But they can now definitively say that Kilauea’s 2018 flank eruption was its biggest in at least 200 years. In the span of about four months, the volcano spilled at least 0.2 cubic miles of lava—that’s over 300,000 Olympic-sized swimming pools of molten rock—over an area of about 13.7 square miles, transforming the landscape and adding more than a square mile of new land to the coast.
It's given scientists a better understanding of magma movements, which hopefully may better inform nearby residents the next time Pele erupts:
Thanks to the scientific instruments HVO already had in place around Kilauea and the additional resources scientists were able mobilize as the eruption revved up, researchers have developed a pretty good picture of how magma moved through the system, and they were able to better constrain how much molten rock is stored there.

A few more observations:
* “something ruptured in that deeper part of the plumbing system” that allowed a lot more magma to move much further down-rift into the LERZ.
Why that deep rupture occurred, we still don’t know,
* The mystery of why Kilauea shut off virtually overnight, Poland said, is perhaps more within reach once researchers combine all the data collected during the eruption with models of fluid flow.
* And there are other mysteries to solve, including what set off the explosive eruptions that rocked the summit crater beginning in May. ... scientists’ initial model of these explosions—as events driven by interactions between magma and groundwater—doesn’t seem to be supported by the new data.
* HVO researchers now have a rare opportunity to watch the volcano’s magma system rebuild itself after a massive bleed-out.

It had my nearly-undivided attention from soup-to-nuts. It is hard to wrap your head around fluid, molten rock flowing like a river, sometimes like whitewater rapids. We live on a very thin crust of hardened rock riding on molten rock, surrounding a ball of white-hot iron, the inner-most under such pressure that although it is white-hot, it stays solid under the unrelenting pressure of the material above. Even after over 4 billion years to cool, it is almost all molten or a white-hot solid.
As large as this eruption was, it was but a speck of sand compared what lies beneath the th[n crust we ride upon.

Having this event happen in our own collective back yard - reminds us of the Mt Saint Helen's event when we were visiting family in Olympia Wa at the time and now even more volatile and closely watched Yellow stone caldera .
We are lucky and blessed to live here .

If Yellowstone erupts, well you won't need to turn out the lights, the airborne volcanic ash will turn them out for you!!! I am also intrigued by Krakatoa and Anak Krakatau.

I lived in Bonney Lake, Washington (near Sumner, Puyallup, etc). The biggest nasty eruption mqy be when Mt. Rainier decides to go. The reason is that, that will set off a Lahar that ill follow a very clear path. That path has huge numbers of homes, developments, towns smack in the middle.

Can we expect a proportionately record-setting lull in volcanic activity this time around?

Our Pele' is just taking a breather - a rest - a pause - she will erupt again but we think MaunaLoa is next prior to Pele' or Yellow stone or Lassen - Rainer or baker .

More comments based on findings in the journal Science:
(
Researchers) will also be keeping a close eye on Mauna Loa—the other major volcano on Hawaii's big island. It has a history of activity when Kilauea goes quiet.

yellowstone is a super volcano. if it were to erupt, it would be what is known as an "extinction event." human civilization as we know it would be numbered in the hundreds of thousands, instead of billions. A similiar event happened a long time ago with the Toba super volcano, creating a climate change event that nearly killed off humanity and caused a genetic bottleneck that exists to this day. Humanity is actually less diverse, genetically speaking, than most mammalian species, due to the bottleneck caused during that period.
