\"bardintzeff-sam_9394-cerro_negro-s\"Le Cerro Negro au Nicaragua (\u00a9 J.M. Bardintzeff).<\/p>\n

Voici ce que j\u2019\u00e9cris \u00e0 propos de la naissance d\u2019un volcan dans mon livre \u00ab\u00a0Volcanologie\u00a0\u00bb (5e<\/sup> \u00e9d., Dunod, 2016)\u00a0:<\/p>\n

De l\u2019accumulation des retomb\u00e9es de type lapilli et blocs-bombes, r\u00e9sulte un \u00e9difice de forme conique (type strombolien).<\/p>\n

La c\u00e9l\u00e8bre histoire du Paricutin illustre bien ceci. Il s\u2019agit d\u2019un volcan, dont la naissance s\u2019est effectu\u00e9e sous l\u2019\u0153il de l\u2019homme. Le 20 f\u00e9vrier 1943, Dioniso Pulido, cultivateur mexicain, observe dans son champ de ma\u00efs, situ\u00e9 pr\u00e8s du village de Paricutin \u00e0 300\u00a0km \u00e0 l’ouest de Mexico, qu\u2019une petite fissure, qu\u2019il se souvenait d\u2019avoir toujours vu l\u00e0, s\u2019\u00e9tait agrandie en une large \u00ab\u00a0crevasse fumante\u00a0\u00bb\u00a0: il s\u2019agissait en fait d\u2019un nouveau volcan, le Paricutin\u00a0! L\u2019\u00e9dification et la croissance du c\u00f4ne de scories ont \u00e9t\u00e9 suivies, jour apr\u00e8s jour.<\/p>\n

On ne conna\u00eet que trois autres exemples de naissance de volcans au cours des temps historiques : le Jorullo, \u00e9galement au Mexique en 1759-1774, le Monte Nuovo dans les champs Phl\u00e9gr\u00e9ens en Italie en 1538 et le Waiowa en Papouasie-Nouvelle-Guin\u00e9e en 1943-1944.<\/p>\n

Pour la sixi\u00e8me \u00e9dition de mon livre, j\u2019ai d\u00e9j\u00e0 pr\u00e9vu de rajouter l\u2019exemple du Cerro Negro\u00a0!<\/p>\n","protected":false},"excerpt":{"rendered":"
