A Hawaiian Volcano Geology Field Trip Video

Just today I got interested in Changbaishan/Baekdu volcano, and there isn’t enough time to do it right by Sunday – it will have to wait until next week.

In the meantime, though, let’s go on a field trip on Kilauea with the University of Hawaii’s Center for the Study of Active Volcanoes!
 

 


Here’s a preview of Changbaishan/Baekdu – it’s sort of Asia’s version of Yellowstone in that it’s a nature preserve as well as a caldera volcano.

Though not “super” in the way that Yellowstone is, Changbaishan/Baekdu can be quite explosive. It’s big one dropped almost 2 inches of ash…on the northernmost island of Japan some 500 miles away!

Here’s what a VEI 7 eruption can look like 1,000 years or so later.
 


 
And this:

A lot like Yellowstone overall.

Those gray pinnacles featured at around 3:30 are exquisitely weathered remains of massive pyroclastic flows. Note all the greenery that’s burying them – it’s an obstacle to observing the volcano from space (preferable because of its politically sensitive location, with two-thirds of it in North Korea).

See? There’s a lot to say about Changbaishan/Baekdu. Just have to think about it a bit more.

More next week!
