Abstract Understanding the relationship between pumice formation and long-term floatability in seawater is becoming increasingly important in terms of eruption dynamics, material cycles, biological and environmental effects, and ocean hazards. Pumice

Abstract Tephra fallout is a potential hazard to livelihoods, critical infrastructure, and health, even in areas that are far from volcanoes. Therefore, it is important to quantitatively evaluate tephra fall hazards for both residents and infrastruct

The Shikotsu-Toya volcanic field (STVF) in southwestern (SW) Hokkaido (Japan) comprises three caldera volcanoes (Toya, Kuttara, and Shikotsu calderas and their post-caldera volcanoes) and Yotei and Shiribetsu stratovolcanoes. The stratigraphy, chrono

Tephra falls can disrupt critical infrastructure, including transportation and electricity networks. Probabilistic assessments of tephra fall hazards have been performed using computational techniques, but it is also important to integrate long-term,

Several global databases of eruption properties have been developed in recent years, which contain eruption age, eruption magnitude, eruption style, and volcanic explosivity index. However, their examinations of the relationships between eruption and

Zircon double-dating utilises (U–Th)/He dating coupled with U–Th disequilibrium or U–Pb dating to determine eruption ages for volcanic rocks between ca. 2 ka to 1 Ma. This approach depends on understanding the crystallisation history of each zi

Zircon U–Pb dating using LA-ICP-MS was applied to three Quaternary tephras in Yakushima Island, southern Japan: the Anbo Tephra, the Koseda pyroclastic flow deposit (Ksd), and the Kikai-Tozurahara (K-Tz) Tephra. The obtained U–Pb ages were 0.73

To understand the eruptive history, structure, and magmatic evolution of Yotei Volcano, southwest Hokkaido, Japan, we investigated the geology and petrology of tephras located around the base of the volcano. We identified 43 tephra units interbedded
