Can anyone tell me why there are volcanos and volcanic flows in Arizona/New Mexico!? There aren’t any hotspots there (that I’m aware of) and it isn’t on a plate boundary. El Malpais NM confuses my amateur geology head🤯

The Yellowstone hotspot- where did it originate and how much does the hotspot move versus the plate above it moving? Do hotspots ever die out?

The lake that formed at the halemaumau crater collapse.... what acidity is it and what gasses are present there? How much do you anticipate this volcanic lake to grow?

I studied NOVARUPTA in Katmai alaska with professor Dr. Houghton (physical volcanologist with HVO) said that this was comparable to Pinatubo.

What is the most unexpected mineral found in the eruption of Mt. St. Helens? And what can that mineral tell us about its magma chamber dynamics?
