Complex styles of phreatomagmatic explosions at Kīlauea Volcano, Hawaii, controlled by magma structure Open
Explosive eruptions at basaltic volcanoes remain poorly understood. Kīlauea Volcano is a type locality for basaltic eruptions and is well-known for effusive activity. However, more than 7 m of phreatomagmatic Keanakākoʻi Tephra unit D depo…

The 2018 Eruption of Kīlauea: Insights, Puzzles, and Opportunities for Volcano Science Open
The science of volcanology advances disproportionately during exceptionally large or well-observed eruptions. The 2018 eruption of Kīlauea Volcano (Hawai‘i) was its most impactful in centuries, involving an outpouring of more than one cubi…

Hawaiian oral traditions and eruptions of Kīlauea Volcano Open
Twenty years ago, I developed an interpretation suggesting that Hawaiian chants [1] involving Pele, the volcano deity, and her youngest sister, Hiʻiaka, metaphorically describe the two largest eruptions of Kīlauea since Polynesian arrival …

Digital rock physics and laboratory considerations on a high-porosity volcanic rock: micro-XRCT data sets Open
Reticulite (high-porosity volcanic rock) is a pyroclastic rock formed during intense Hawaiian fountaining events. The honeycombed network of bubbles is supported by glassy threads and forms a structure with a porosity of more than 80 %. It…
