Workshop ERI-IPGP 2024

L'Earthquake Research Institute (Université de Tokyo) a été créé en 1925 après le grand tremblement de terre de Kanto (1923). Sur la base d'un accord signé avec l'IPGP en 2001, les deux instituts organisent des workshops biannuels à Tokyo et à Paris, alternativement. Pour cette huitième édition et pour la première fois, l'IPGP accueille 25 Tokyoïtes pour faire le point sur l'avenir de cette collaboration.
