Africa-Press – Senegal. <\/strong><\/span>A\u0300 l\u2019occasion de la sortie de mon livre \u00ab Les secrets de la Fournaise \u00bb, je vous re\u0301ve\u0300le quelques-uns de ces secrets, pour une mini-se\u0301rie d\u2019articles sur ce volcan franc\u0327ais parmi les plus actifs de la plane\u0300te: le Piton de la Fournaise ! Aujourd\u2019hui, coup de projecteur sur les risques associe\u0301s a\u0300 ce volcan qui sont finalement tre\u0300s faibles. La Fournaise ne fait pas peur aux Re\u0301unionnais et c\u2019est me\u0302me tout l\u2019inverse, car le volcan attire bien des curieux…<\/p>\n

Quelque 97 % des e\u0301ruptions du Piton de la Fournaise se produisent a\u0300 l’inte\u0301rieur de l’Enclos Fouque\u0301, cette vaste de\u0301pression topographique de 8 kilome\u0300tres par 13, au centre de laquelle se trouve le sommet du volcan. Par ailleurs, mis a\u0300 part quelques rares cas exceptionnels, les e\u0301ruptions de ce volcan sont faiblement explosives, avec des projections volcaniques qui de\u0301passent rarement 200 me\u0300tres de haut. Ce sont donc essentiellement les coule\u0301es de lave qui menacent… Mais comme personne n’habite a\u0300 l’inte\u0301rieur de cet Enclos, les seuls enjeux concernent les instruments de surveillance, les sentiers et la route nationale a\u0300 basse altitude, que la lave recouvre parfois.<\/p>\n

En revanche, ces e\u0301ruptions attirent de nombreux spectateurs sur le bord de l’Enclos, pour un son et lumie\u0300re naturel unique et envou\u0302tant ! Avec ses e\u0301ruptions et ses paysages uniques, le Piton de la Fournaise est ainsi un des principaux attraits de l’i\u0302le de La Re\u0301union: le volcan fait donc vivre bien plus de personnes qu’il n’en menace !<\/p>\n

Et des e\u0301ruptions hors Enclos…<\/b><\/p>\n

Ce constat formule\u0301, il convient de pre\u0301ciser qu’assez rarement, il arrive que les zones de faiblesse du volcan drainent la lave en dehors de l’Enclos, vers le nord-est ou le sud-est. Ces e\u0301ruptions sont assez rares, mais la lave s’e\u0301panche alors vers les zones habite\u0301es, ce qui peut engendrer des de\u0301ga\u0302ts. C’est ainsi que l’e\u0301ruption hors Enclos de 1977 de\u0301truisit une trentaine de maisons dans le village de Piton Sainte-Rose, ainsi que 290 hectares de terres agricoles et obligea l’e\u0301vacuation de 2 500 habitants.<\/p>\n

\u00ab Les secrets de la Fournaise \u00bb, un livre pour tous !<\/b><\/p>\n

Cet ouvrage, c’est a\u0300 la fois un beau livre et un guide de randonne\u0301e, qui comporte en plus quelques informations pour les enfants ! Ce livre 3 en 1 vous permettra ainsi de comprendre le fonctionnement de ce volcan passionnant, mais aussi d’appre\u0301hender le paysage observe\u0301 depuis le sentier qui me\u0300ne au bord du crate\u0300re Dolomieu. Et ce, tout en profitant de belles photos d’e\u0301ruptions re\u0301centes !<\/p>\n

Il ravira ainsi le passionne\u0301 de nature et ce, me\u0302me s’il n’a jamais foule\u0301 cette merveilleuse i\u0302le de La Re\u0301union, car cet environnement volcanique rare est particulie\u0300rement riche et inte\u0301ressant ! Il devrait aussi bien su\u0302r contenter ceux qui ont grimpe\u0301 jusqu’au sommet de la Fournaise, car cette randonne\u0301e pose bien des questions… Des re\u0301ponses oui, vous en aurez, mais de nouvelles questions se poseront e\u0301galement ! La science est comme cela…<\/p>\n

Ce livre est une porte vers un monde particulier, un monde en e\u0301volution perpe\u0301tuelle, un monde qui rappelle que notre Plane\u0300te est vivante, un monde en fait tre\u0300s proche des Hommes…<\/p>\n
