Volcano Awareness Month 2022 Short Feature — Kīlauea’s recent explosive history

Join USGS Hawaiian Volcano Observatory retired geologist Don Swanson on a virtual field visit to an exposure of the Keanakāko‘i Tephra near the summit of Kīlauea as part of Volcano Awareness Month. This exposure shows deposits of explosive eruptions of Kīlauea between 500 and 230 years ago, from just after the modern caldera formed to the lethal explosive eruption of 1790.

Volcano Awareness Month is spearheaded by the USGS–Hawaiian Volcano Observatory, in cooperation with Hawai‘i Volcanoes National Park, Hawaii County Civil Defense Agency, and the University of Hawai‘i at Hilo, and provides informative and engaging public programs about the science and hazards of Hawaiian volcanoes.
