1. 13:30-13:45

TITLE: Tectonic tremor distribution and migration at Kumano-nada: insights from ocean-bottom seismometer deployment between DONET1 and 2

AUTHOR: *Takeshi AKUHARA, Yusuke YAMASHITA (Kyoto Univ.), Hiroko SUGIOKA (Kobe Univ.), Farazi Atikul HAQUE・Shukei OHYANAGI・Yoshihiro ITO (Kyoto Univ.), Eiichiro ARAKI, Takashi TONEGAWA (JAMSTEC), Takeshi TSUJI (Tokyo Univ.), Ryosuke AZUMA・Ryota HINO (Tohoku Univ.), Kimihiro MOCHIZUKI・Shunsuke TAKEMURA・Tomoaki YAMADA and Masanao SHINOHARA

2. 13:45-14:00

TITLE: Towards high-resolution simulation of post-disaster economy


SUMMARY: We developed an Agent-based system to simulate Japanese economy in high resolution and validated by comparing with past data, and working on extending it to simulate post-disaster economy.

3. 14:00-14:15

TITLE: Synergistic Approach to Robustly Reconstruct Eruption

Plume Dynamics: Application to Campi Flegrei, Italy.

AUTHOR: *Beatriz MARTINEZ MONTESINOS・Yujiro J SUZUKI, Antonio COSTA(National Institute of Geophysics and Volcanology, Bologna, Italy) and Leonardo MINGARI(Geosciences Barcelona (GEO3BCN), The Spanish National Research Council (CSIC), Spain)

SUMMARY: We use the FALL3D ash dispersal model to determine source conditions by inverting field data within an ensemble-based method, and the SK3D model to resolve the volcanic plume. The estimation of the eruption source parameters obtained from one approach is used in the other to better reconstruct the eruption plume dynamics of the ~39 ka Campanian Ignimbrite super-eruption in Campi Flegrei, Italy.
