Sur France Info, Daniel Fievet propose une chronique dédiée aux supervolcans et à leurs éruptions. Quelques minutes tout à fait dignes d'intérêt sur une expérience scientifique visant à mieux comprendre les raisons de ces explosions particulièrement dévastatrices. Bien sûr on y parle du Yellowstone, et de son éruption remontant à environ 600 000 ans. Mais si les conséquences d'une nouvelle éruption seraient aujourd'hui catastrophiques pour l'homme, un tel phénomène est très peu probable. Aucun des 20 supervolcans recensés sur la planète ne menace d'exploser, et leur chambre magmatique se remplit suffisamment lentement pour que l'on soit tranquille encore quelques centaines de milliers d'années. Découvrez notre séjour dans le Parc National du Yellowstone, pour en comprendre les phénomènes géologiques grâce à la présence du volcanologue Jacques-Marie Bardintzeff.
