Laboratoire International Associé

The Laboratoire International Associé “Montessus de Ballore” is a collaborative structure, created in 2006, between the French CNRS-INSU and the Universidad de Chile (Santiago), involving in particular the Institut de Physique du Globe de Paris and the Ecole Normale Supérieure de Paris. The aim is to structure the long standing collaborations between French and Chilean teams in the understanding and the modelling of transient deformation processes along the active subduction zone of Chile for improving physics based monitoring and earthquake hazard assessment in this area. The main French-Chilean efforts lead to the deployment of state-of-the art monitoring systems - combining seismology, geodesy, geology and satellite imaging – in the regions of Central and North Chile. The recent large earthquakes of Tocopilla (Mw 7.7, 2007, North Chile), Maule (Mw 8.8, 2010, Central Chile), Iquique (Mw 8.4, 2014, North Chile), Illapel (Mw 8.3, 2015, Central Chile) have been very well recorded and have unraveled new complexity of the subduction interface and of large earthquake cycle in this area, which raises new scientific questions .
