  • L’histoire : Les expéditions de Paul Gaimard en Islande, 1835–1836
    Page 18-23

En 1835–1836, le naturaliste français Paul Gaimard mène deux expéditions en Islande. Les scientifiques étudient l’île sous tous les aspects : botanique, zoologie, météorologie, histoire, ethnographie, linguistique… Ici, nous nous focalisons sur les manifestations volcaniques du pays (Geysir, le mont Hekla…) et sur les théories géologiques de l’époque pour tenter d’expliquer ces phénomènes.

  • Le dossier : Bombes volcaniques, un portrait de famille
    Page 24-31

Les bombes volcaniques, ces grosses gouttes de magma expulsées par les cratères, peuvent prendre des formes très variées en fonction des conditions éruptives. À ces formes correspondent autant de noms fleuris : bombe en fuseau, en bouse de vache, en chou-fleur… Nous vous proposons une revue (non exhaustive) de cette grande famille.

  • L’image : Les paysages volcaniques de Georgia O’Keeffe
    Page 32-36

Artiste emblématique du mouvement moderniste américain, Georgia O’Keeffe passa la seconde moitié de sa vie au Nouveau-Mexique, où elle peignit sans relâche des paysages fantastiques façonnés par des millions d’années de volcanisme. Grande voyageuse, elle représenta aussi quelques volcans aperçus lors de ses périples aux quatre coins du monde.

  • Le volcan : Santa María, Guatemala
    Page 37-41

Pas forcément le plus connu des volcans du Guatemala, le Santa María est en tous cas le plus destructeur de l’histoire récente du pays. En 1902, ce grand stratovolcan – que d’aucuns pensaient éteint – a produit une éruption plinienne majeure, l’une des plus importantes du xxe siècle. Depuis, son activité est marquée par l’émission des dômes de lave de Santiaguito.

  • La question : Quel est le volcan le plus étudié ?
    Page 46-49

Les biologistes ont leurs espèces « stars » des laboratoires, les organismes modèles. Souris, drosophile, poisson-zèbre… ou encore l’arabette des dames chez les végétaux. Les géologues aussi ont leurs volcans stars, des édifices qui font l’objet de très nombreux travaux. Mais lequel d’entre eux détient la palme ? Pour le savoir, troquons la volcanologie pour la bibliométrie.
