Volcano Watch - Geology of the past, how long will the eruption last?

The 2018 lower East Rift Zone (LERZ) eruption of Kīlauea brought an end to the 35+ year eruption at Pu‘u ‘Ō‘ō. With the draining of the summit and the collapse of Pu‘u ‘Ō‘ō, Puna residents were concerned that the eruption in the LERZ could be long-lived.

Volcano Watch - A Field Trip to the Mountain of Water

The field day begins with a summit weather check at first light. It is a reflective moment at 6:15 AM atop Kīlauea Volcano, and the fumarole cracks are steaming like the coffee from my thermos.
