L' American Geophysical Union (AGU) organise la plus importante rencontre internationale en Sciences de la Terre et de l'Espace. Ce meeting permet chaque année aux experts du monde entier de se rencontrer et d'échanger sur leur thématique.
Cette année l'évènement fête ses 100 ans d'existence en présence de 24 Géoazuréens du 9 au 13 décembre 2019 à San Francisco.
59 présentations orales ou posters impliquant un membre de Geéoazur seront présentées
