1. 13:30-13:45
TITLE: Current state of economic simulations for disaster applications and its future directions
AUTHOR: *MADDEGEDARA Lalith, Amit GILL, Tsuyoshi ICHIMURA, Kohei FUJIA and Mueno HORI(JAMSTEC)
SUMMARY: We present a review of the current progress of economic simulations and the future directions required for accurately evaluating the post-disaster economy at high resolution.
2. 13:45-14:00
TITLE: Column collapse conditions leading to low-temperature pyroclastic density currents
AUTHOR: *Yujiro J. SUZUKI
SUMMARY: Conditions for the generation of pyroclastic density currents, as observed in phreatic explosions, were estimated through numerical simulations.
