The quantitative assessment of volcanic unrest is essential for understanding volcanic processes and supporting decision-making. However, systematic approaches to evaluating unrest episodes remain underdeveloped, particularly during non-eruptive periods. The Volcanic Unrest Index (VUI), originally proposed in New Zealand as a communication tool, …

Abstract To investigate the magma plumbing system beneath the Akan Caldera (Hokkaido, Japan), we conducted broadband magnetotelluric surveys and imaged its three-dimensional resistivity structure to a depth of approximately 30 km. The caldera hosts post-caldera volcanoes, including Mt. Meakandake and Mt. Oakandake, …
