1. 13:30-13:45

TITLE: Seismic evidence for discovering long-rest active volcanoes in Taiwan

AUTHOR: *Cheng-Horng LIN

SUMMARY: The Tatun volcano group (TVG) is a long-rest volcano and there was no eruption record in the human history. The detailed seismic examinations not only clearly identify a magma reservoir exists beneath TVG, but also show some interesting volcano-seismic features such as heartbeat-like swarms, seismicity conduit and mantle-wedge diapers.

2. 13:45-14:00

TITLE: Implications of fault-valve behavior from immediate aftershocks following the 2023 Mj6.5 earthquake beneath the Noto Peninsula, central Japan


SUMMARY: We identify a rapid migration of early aftershocks following the largest 2023 Mj6.5 earthquake during a long-lasting intense seismic swarm in the Noto Peninsula, which the upwelling of crustal fluids along the fractured permeable fault zone might explain.

3. 14:00-14:15

TITLE: Early report on preliminary analysis of enigmatic tsunamis generated in southwest of Torishima Island on 9 October 2023

AUTHOR: *Osamu SANDANBATA・Kenji SATAKE・Shunsuke TAKEMURA・Shigo WATADA and Takuto MAEDA(Hirosaki University)

SUMMARY: We will overview the enigmatic tsunami event from south of Torishima Island, and show results of preliminary analysis of tsunami data recorded by ocean-bottom-pressure gauges of DONET, provided by NIED.
