Les volcans de boue ne r\u00e9sultent nullement d\u2019un processus magmatique\u00a0: ils tiennent leur nom de leur activit\u00e9 \u00ab\u00a0explosive\u00a0\u00bb et aussi de leur forme (c\u00f4ne miniature, le plus souvent de quelques dizaines de centim\u00e8tres ou quelques m\u00e8tres de haut). Un millier sont connus dans le monde, essentiellement dans des zones en compression\u00a0: Italie (Maccalube en Sicile et dans la r\u00e9gion de Mod\u00e8ne dans les Apennins), Roumanie, Azerba\u00efdjan, Pakistan (o\u00f9 ils peuvent mesurer plusieurs centaines de m\u00e8tres de haut), Bangladesh, Myanmar, Trinit\u00e9-et-Tobago, Barbade. Ils existent en mer aussi (M\u00e9diterran\u00e9e, Atlantique, mer Noire, mer Caspienne). Ils \u00e9mettent des gaz d\u2019origine profonde, du m\u00e9thane essentiellement (94-97% pour Maccalube) qui s\u2019enflamme parfois spontan\u00e9ment mais aussi CO2<\/sub>, H2<\/sub>S, O2<\/sub>, N2<\/sub>, CO, des gaz rares (Ar, He, Ne, Kr, Xe). Il s\u2019agit parfois simplement de gaz bact\u00e9riens d\u2019origine peu profonde.<\/p>\n
