Abstract:
Tsunamis are generated not only by large earthquakes but also by submarine volcanic activity beneath/near the ocean. I have recently shown the recurrence of atypical earthquakes and tsunamis due to intra-caldera faulting events, called trapdoor faulting, in submarine calderas. In this talk, I will provide comprehensive overview of key findings on submarine trapdoor faulting, through case studies of Sumisu Caldera (Japan), Curtis Caldera (New Zealand), and Kita-Ioto Caldera (Japan).
