Submarine cores record magma evolution toward a catastrophic eruption at Kikai Caldera

T. Hanyu, N. Seama, et al.

Explore the intriguing findings of a study that delves into the magma evolution leading to caldera-forming eruptions near Kikai Caldera, Japan. Conducted by Takeshi Hanyu and colleagues, this research uncovers the critical role of mafic and felsic magmas in shaping volcanic activity over thousands of years.

Abstract
Magma evolution toward a caldera-forming eruption remains uncertain due to a lack of successive volcanic records. This study analyzes a submarine core near Kikai Caldera, Japan, which recorded two caldera-forming eruptions and smaller eruptions between them. The discovery of mafic glass fragments in the 95-ka eruption deposits suggests mafic magma involvement. Inter-caldera activity showed binary mafic and felsic magma extrusions, shifting to felsic dominance. The final stage before the 7.3-ka eruption lacked the most felsic composition, suggesting felsic melt accumulation for the next catastrophic event.
