Professor of geophysics at the University of Paris-Diderot, and a researcher in physical volcanology, he is one of the world's leading specialists in natural hazards of geological origin.
By a presidential decree of 12 January 2011,[1] he succeeded Vincent Courtillot as head of the Institute of Earth Physics in Paris.
Claude Jaupart's work focuses on the thermal structure of continents, the characteristics of the internal movements of our planet responsible for continental drift and the modalities of volcanic eruptions.
How the movements and distribution of temperatures within the Earth are affected by the large variations in viscosity that prevail there and by the presence of continents.
(6) Physics of volcanic eruptions: importance of gas leaks through the walls of a conduit, importance of coupling between flow at the surface and in an eruptive conduit, effects of compressibility on lava flows, effects of fragmentation and fragment size distribution (pumice and ash) on the behaviour of eruptive plumes in the atmosphere.
