E-GRAAL (Earthquake GRAvity ALerts) 2nd meeting

jeudi 6 oct. 2016, 09:00 → 19:30 Europe/Paris

Meeting room 3000 - 3rd Floor (IPGP)

The goal of the E-GRAAL project is to study the feasibility of a new earthquake early-warning system using the detection of the gravity perturbation during the fault rupture
