Throughout the 2018 eruption of Kīlauea volcano (Hawai‘i), episodic collapses of a portion of the volcano’s summit caldera produced repeated Mw">Mw 4.9–5.3 earthquakes. Each of these 62 events was characterized by a very‐long‐period (VLP)...
Caldera collapse geometry revealed by near‐field GPS displacements at Kilauea Volcano in 2018
Paul Segall, Kyle R. Anderson, Fabio Pulvirenti, Taiyi Wang, Ingrid A. Johanson
2020, Geophysical Research Letters (47)
We employ near‐field GPS data to determine the subsurface geometry of a collapsing caldera during the 2018 Kīlauea eruption. Collapse occurred in 62 discrete events, with “inflationary” deformation external to the collapse, similar to previous basaltic collapses. We take advantage of GPS data from the collapsing block and independent constraints...

Mechanics of inflationary deformation during Caldera collapse: Evidence from the 2018 Kīlauea Eruption
Paul Segall, Kyle R. Anderson, Ingrid A. Johanson, Asta Miklius
2019, Geophysical Research Letters (46) 11782-11789
During the 2018 Kilauea eruption the caldera ffloor dropped 500 meters in 62 nearly periodic events of up to 8 meters. Caldera collapse maintains pressure in the magma reservoir necessary to sustain high-rate eruptions. The 2018 collapses were accompanied by inflationary tilts and displacements, similar to observations at other basaltic...

Paul A. Hsieh, Steven E. Ingebritsen
2019, Journal of Geophysical Research (124) 1498-1506
The many successes in volcano forecasting over the past several decades owe mainly to pattern recognition, both in monitoring data and the geologic record. During the early stages of the 2018 Kīlauea eruption, the conceptual model of Stearns (1925), based on the explosive 1924 Kīlauea eruption, was highly influential....
Dikes in the Koaʻe fault system, and the Koaʻe-east rift zone structural grain at Kīlauea Volcano, Hawaii
Donald A. Swanson, Richard S. Fiske, Carl Thornber, Michael P. Poland
2019, Book chapter, Field volcanology: A tribute to the distinguished career of Don Swanson
Two small scoria vents were discovered in the Koa‘e fault system, an extensional regime connecting the east and southwest rift zones of Kīlauea that was previously considered to be noneruptive. The chemical composition of the scoria suggests an early to middle nineteenth-century age. The vents prove that magma can intrude...
