1. 13:30-13:45

TITLE: Origins of the tsunami following the 2023 Turkey–Syria earthquake

AUTHOR: *Gui HU・Kenji SATAKE, Linlin LI・Peng DU (Sun Yat-sen University)

SUMMARY: We analyzed waveforms of small tsunami generated by the Turkey–Syria earthquake to examine the origins.

2. 13:45-14:00

TITLE: Regionality of upper mantle conductivity inferred from geomagnetic

daily variation analysis

AUTHOR: *Takao KOYAMA, Shigeru FUJITA (The Institute of Statistical

Mathematics), Ikuko FUJII (Meteorological College), Kiyoshi BABA and

Hisayoshi SHIMIZU

SUMMARY: We estimated the electrical conductivity anomaly in the upper mantle by using a geomagnetic daily variation model based on the Ground-to-topside model of Atmosphere and Ionosphere for Aeronomy.

3. 14:00-14:15

TITLE: Precursory deformation associated with the 2017 and 2018 eruption of Shinmoe-dake volcano detected by satellite SAR


SUMMARY: We investigated the spatio-temporal variation of ground deformation prior to the 2017 and 2018 eruption of Shinmoe-dake volcano based on the result of SAR time-series analysis.
