http:\/\/www.ingv.it\/<\/a><\/p>\nLe sc\u00e9nario est quasi toujours le m\u00eame\u00a0: le paroxysme dure de 1 \u00e0 3 h, il commence par une activit\u00e9 strombolienne (projections de bombes), puis des fontaines de lave montent \u00e0 500-1000 m de haut, surmont\u00e9es d\u2019un panache de cendres et lapilli de plusieurs km, entra\u00een\u00e9 par le vent (ce qui peut occasionner la fermeture de l\u2019a\u00e9roport de Catane pendant quelques heures), coul\u00e9es de lave mod\u00e9r\u00e9es (2-4 km) en direction essentiellement du Val del Bove, accompagn\u00e9es parfois de petits \u00e9coulements pyroclastiques. Entre les paroxysmes (1 \u00e0 4 jours) l\u2019Etna semble presque mort\u00a0!<\/p>\n
Je suis all\u00e9 me rendre compte sur place, en compagnie de Sylvain Chermette (g\u00e9rant de \u00ab 80 Jours Voyages \u00bb). Merci \u00e0 Boris Behncke (INGV), Pippo Scarpinati et Anne Fornier pour leur aide.<\/p>\n
