On a sidenote, I think I’ve finally figured out that the vog blowing in from the Big Island is what triggers my allergies. Once Mauna Loa started dumping various gases into the air at a huge rate, my eyes started itching madly. The last time they were doing this was pre-COVID, during the Kilauea eruption that took out a couple of housing developments.
I remember reading about those many years ago in my early elementary schools days, but haven’t thought about them in just about as many years. Thanks for the reminder!
Gotta add the word “active” in there too. If the La Garita Caldera (or even the slightly smaller Yellowstone Caldera, which is just a baby in the geological timescale) goes off it’s not going to be a fun news story with pretty photos.
Colorado. La Garita is probably not much of a hazard because it last erupted 28 million years ago. But it was among the largest known eruptions in earth’s history. Bigger than Yellowstone and officially classified as a “Mega-colossal” eruption event which is five categories worse than “severe.”
In contrast the current Mauna Loa eruption is the lowest classification, “effusive.”
Mauna Kea last erupted about 4,500 years ago and is likely to erupt again. Its quiescent periods between eruptions are long compared to those of the active volcanoes Hualālai (which erupts every few hundred years), Mauna Loa (which erupts every few years to few tens of years) and Kīlauea (which erupts every few years).
