Greetings and thank you from Oregon!

Volcanoes are beautiful to look at. This one seems to have suffered a flank collapse ar one time...

I read the whole Wiki article and there is no use of the phrase "flank collapse," but I didn't actually understand what I was reading. This could be the info we're looking for: "A large ice-age glacier on the northeast side of the volcano severely eroded that part of the mountain, creating an asymmetrical cone. A cirque glacier occupied part of the depression until early in the 20th century." In fact, the collapsed part in the photo is the northeast side. What do you think?

Ah, a glacier, that explains it! That's harmless... :-) Flank collapse is when the flank of the mountain collapses during eruption in Mt. St.Helen's style, a very serious scenario. You wouldn't want to be anywhere near that.

Oh, you're brilliant! Gudrun, what great info and I'll always go to you for any geological translations I might need!

Lol, I'm just an interested amateur;-)

Is it still active?

I can't find anything that says one way or another. One source notes that the youngest of the lava flows is probably 20-30,000 years old. The volcano has a history too complex for me to understand, but it does not seem "active" in the sense that it could blow any time, now. Good to know!

Active or not, collapsed or eroded - your photo is a very beautiful compo and a good work.
