A note from the Tangentially Related to Kumamoto Desk: Hawaii’s Kilauea volcano, one of the world’s most active, has erupted again to no one’s surprise. It differs greatly from Aso in that it is caused by a hot spot in the mantle so extrudes iron-rich magma, whereas Aso is due to subductive activity so emits igneous rock and ash (a lot of ash). We talked recently about the black color of Aso’s emittances; those in Hawaii, due to the iron content, tend to be red (and thus so is most Hawaiian dirt). Below is a photo of a smoke plume from Kilauea: It’s pink! Aso would be so much cooler if it emitted pink ash! But you live within the ash color spectrum of the volcanoes you’re given, not that of those you might prefer. - William
