ERI-IPGP Workshop 2024

Earthquake research institute, university of Tokyo is founded in 1925 after the great Kanto earthquake (1923). Based on the memory of understanding with IPGP signed on 2001, two institutes are holding biannual workshop in Tokyo and in Paris, alternatively. There are continuous flow of researchers and students, with a fruit of around twenty publications per year coming from a tight collaboration. This is the eighth edition and for the first time in the history, we welcome 25 Tokyoites in order to review the collaborations and propose new horizons to come.
