Just a report on a few minor quakes at another cinder cone/uplift area thats part of the Newberry Region. Not much to tell here yet, other then there is a slight indication of a trend with the quakes becoming shallower. Like the Cryder Butte quakes, mosting posting it as seismic readings around cinder cones arn't common. It doesn't mean the cinder cones are going active, or anything like that.

Just a report on a few minor quakes at another cinder cone/uplift area thats part of the Newberry Region. Not much to tell here yet, other then there is a slight indication of a trend with the quakes becoming shallower. Like the Cryder Butte quakes, mosting posting it as seismic readings around cinder cones arn't common. It doesn't mean the cinder cones are going active, or anything like that.



Is "going active" something cinder cones can do? My impression was that they're pretty much one-and-done. A new one, on the other hand, would be pretty interesting.

You are right in that thy are one, and done. But they do -cluster- together in groups quite frequently.

Here are my two favorite clutters, on one map. https://maps.google.com/maps?q=43.888986,-121.678445&hl=en&ll=43.882057,-121.624146&spn=0.175694,0.372505&num=1&t=p&z=12

Thank you, that's pretty much what a figured. That's a pretty awesome area. We touristed through there last year enjoying the volcanoes but didn't realize there were so many!

That's a typo that kind of works!

Per surface area (not including oceanic ridge zones), I think Oregon has the most Volcanos and Cinder cones on the planet. I love those to Cinder Cone Arch's on that map. I suspect it's what happens when magma comes up to the surface along a fault/fracture zone instead of a chimney. It might also be related to that area is transitional from subduction volcanism in the mountain rage, to hot spot volcanism at Newberry. Just my best guesses, I haven't ever seen a write-up done about them, other then how abundant cinder cones are in that region.
