Workshop Magellan³ : Submarine Hazards, Responses, and Eruption Cycles from Kikai Caldera

La communauté est invitée à s’inscrire au Workshop ECORD/Magellan³ intitulé « Submarine Hazards, Responses, and Eruption Cycles from Kikai Caldera » qui se tiendra à l’Université de Kobe (Japon) du 15 au 17 mars 2027. Il est possible de demander un financement pour y participer

Contenu scientifique (en anglais)

Caldera volcanism generates catastrophic geohazards, including tsunamis, seafloor disruption, and widespread ash dispersal, that alter regional landscapes and global climate. Despite extreme socio-economic risks, submarine caldera complexes and their eruption cycles remain poorly understood. The mostly submerged Kikai Caldera (Japan) is the ideal natural laboratory to resolve these blind spots via deep drilling. We hold the SHREK Magellan³ workshop in Kobe, Japan, to advance our active IODP³ pre-proposal (1122-Pre) into a full drilling proposal. The workshop will refine core scientific hypotheses and define optimal drilling targets for the R/V Chikyu.

Preliminary working hypotheses identified and which will be discussed during the proposed Magellan³ workshop in Kobe are:

• The Kikai volcanic system has grown through multiple Quaternary caldera cycles, involving more frequent large eruptions than currently known, affecting the seafloor and mainland Japan.

• The recent lava dome and sediment accumulations within Kikai Caldera record the early inter-caldera stage of the volcanic system and the systematics behind recurrent silicic caldera cycles in coastal volcanic fields.

• Caldera-forming volcanism in the extensional Northern Ryukyu region includes progressively increasing caldera sizes modulated by external forces, such as tectonics and climate.

• Ash alteration and hydrothermal fluids create redox, nutrient, and metal gradients that structure subseafloor microbial communities and control biogeochemical recovery after large eruptions.

• Larger eruptions of Northern Ryukyu arc calderas have modulated and shaped the regional climate and ecology.
