TITLE: Adaptive and automatic P- and S-phase pickers based on frequency spectrum variation of sliding time windows<\/p>\n\n\n\n
AUTHOR: *Yijun ZHANG, Qiang CHEN and Xianwen LIU(Southwest Jiatong University\uff09<\/p>\n\n\n\n
SUMMARY: We here develop a new refining picker which adopts the frequency spectrum variation analysis (FSVA) to perform the adaptive phase onset identification for P and S-wave<\/p>\n\n\n\n
2. 13:45-14:00<\/p>\n\n\n\n
TITLE: Extension of Cellular Automata Research to Dynamic Fracture<\/p>\n\n\n\n
AUTHOR: *Kota FUKUDA, Takahiro HATANO(Osaka University) and Kimihiro MOCHIZUKI<\/p>\n\n\n\n
SUMMARY: We propose a cellular automaton model that can handle both rupture and seismic activity, and point out the importance of considering competing time constants.<\/p>\n\n\n\n
3. 14:00-14:15<\/p>\n\n\n\n
TITLE: TITLE: Analyses of seismo-acoustic data and satellite images extracting the January 2022 eruption sequence of a submarine volcano in Tonga<\/p>\n\n\n\n
AUTHOR: *Mie ICHIHARA\uff65Kiwamu NISHIDA\uff65Takayuki KANEKO, Aika KUROKAWA(NIED) and Setsuya NAKADA<\/p>\n\n\n\n
SUMMARY: The eruption generated huge waves in the atmosphere, ocean, and solid earth. This study focuses on the volcanic activity in three days including the huge explosion.<\/p>\n\n\n\n
4. 14:15-14:30<\/p>\n\n\n\n
TITLE: Gravity changes associated with volcanic eruption in Tonga on January 15, 2022 recorded by superconducting gravimeter at Matsushiro<\/p>\n\n\n\n
