Use of scientific knowledge for risk reduction purposes: what the Mayotte seismo-volcanic crisis teaches us

Louise Le Vagueresse’s thesis focuses on the use of scientific knowledge for risk reduction purposes and takes as a case study the seismo-volcanic crisis that began in Mayotte in May 2018. It aims to identify and characterize this which today stands in the way of an effective mobilization of the scientific knowledge produced by the geosciences. To this end, it combines geosciences – on data and models of deformation and seismicity, and their uncertainties – and social sciences – survey work and interviews with actors, development of experimental systems for sharing knowledge with schoolchildren, etc. – especially in the field, in Mayotte.
