100 years ago at Kīlauea: The 1924 explosive eruption described by Thomas Jaggar 

I read about that, kind of fluke if I recall.

@@melodiefrances3898 No fluke … Scientists have recently been digging around Kilauea and have new evidence that pyroclastic events as they like to call it have happen several times . .. The history is there for geologist to discover in the layers .

And we still do! It's a magical sight to witness.

Amen ... did the helicopter flight looking down in the cone seeing the molten lava ... pouring slowly through the pods as grew and moved down to the sea. As you say ... a magical ... mystical experience. What meaning is there ... but the obvious. The Force behind Creation ... TAINT FINISHED ... and so I have a choice of FITTING only in the NOW.

What to learn from this - if your last name is Truman, do not approach volcanoes.

Uncanny how history repeats its self 😮

You are mixing up different timescales the eruption in question from Yellowstone was 640 thousand years not million that is 3 orders of magnitude different.

Yellowstone's most recent caldera-forming eruption was 631,000 years ago. There was no ice covering the area at the time. Lava flow eruptions have happened when the region was glaciated, however -- about 130,000-150,000 years ago. Some of the lava flows that erupted during this time (www.usgs.gov/observatories/yvo/news/lotta-lava-new-insights-timing-yellowstones-most-recent-rhyolite-eruptions) show signs of having interacted with ice, and there is evidence that glacial lakes might have been present in the region at various times. More information about Yellowstone's glacial history is at www.usgs.gov/news/yellowstones-icy-past.

@usgs thanks for answering me. I see what I did. I was reading about snowball earth, then pangea, which made me think about Yellowstone, and all I saw was 640. I had millions on my mind. Lol. Thank you for taking the time to point out my mistake. Peace and Ahev

@@usgs Isn't ice what makes volcanism on Iceland form steeper features? Normally Icelandic volcanoes form shields, but around the recent eruptions there are some steep and tall features. I imagine that happens when the lava extrusion is under a glacier which cools the lava rapidly and makes it deposit closer to the eruption site.

@@HotelPapa100 Yes indeed! subglacial eruptions can generate a lot of ashy debris, called hyaloclastite, and lead to steeper features once the ice melts. These are called tuyas, and you can find them all over Iceland, as well as in British Columbia (Canada)!

What? No! That's normal in Hawaii, or any volcano when water meets magma.

@@sigisoltau6073 “Normal” since 1850.

@@HDPersonal777 Where did you come with that date? Specifically? These kinds of phreatic eruptions can happen on any volcano whenever water comes into contact with magma. Both after and before 1850 since the earth, volcanoes and water have existed for over 4 billion years.

@@sigisoltau6073 Where is your proof? Real proof? Besides someone saying that timeline based on no facts. Maybe you should research silicone vs. carbon eras, etc.

@@HDPersonal777 Really? You're asking me for proof? Shouldn't you provide proof for your claim about 1850? Or that these DEW existed back then. Or that they were used to start volcanic eruptions. Let's see. There's radiometric and potassium-argon dating that shows the earth is billions of years old. In rock layers we can see evidence of lava flows and pyroclastic deposits. Both are evidence that volcanic eruptions have been going on long before 1850.
