… et le Mauna Loa<\/h2>\n\n\n\n

Ce sont les deux sommets de l’\u00eele. 4205m pour le Mauna Kea, 4169m pour le Mauna Loa.
Ce sont tous deux des volcans.
Le Mauna Kea, endormi, n’a pas boug\u00e9 depuis 4500 ans.
Le Mauna Loa est bien actif lui, avec en moyenne une \u00e9ruption tous les 5 ans. Il d\u00e9gage aussi des gaz irritants.
Ils crachent des laves fluides, qui forment les nombreuses coul\u00e9es observables autour de l’\u00eele, mais n’explosent pas.<\/p>\n\n\n\n

On distingue bien en haut le Mauna Kea avec sa vieille lave couleur brique \/ jaune, et le Mauna Lea qui occupe la majeure partie de l’\u00eele, avec toutes ses noires coul\u00e9es de lave r\u00e9cente. En bas \u00e0 droite, le jeune Kilauea<\/a> et ses modestes coul\u00e9es noires, actif quasi en permanence, \u00e9met un petit panache de fum\u00e9e…<\/p>\n\n\n\n

Le sommet du calme Mauna Kea est occup\u00e9 par de nombreux t\u00e9lescopes, Ce n’est pas tr\u00e8s “nature”…Tous les carr\u00e9s sont des t\u00e9lescopes. La France y participe modestement.<\/p>\n\n\n\n

Sur le site de la maison du tourisme, \u00e0 2800m, il y a aussi le Halepohaku Onizuka, h\u00e9bergement collectif (env. 70 pers;) pour les astronomes du monde entier qui viennent profiter de l’atmosph\u00e8re pure de cette \u00eele perdue au milieu de l’oc\u00e9an. Ils peuvent exploiter les nombreux \u00e9quipements du sommet depuis cette altitude plus vivable.<\/p>\n\n\n\n

Le volcan a connu une pr\u00e9sence humaine : les maorais venaient rechercher la pierre de lave sur les pentes pour r\u00e9aliser des hachettes\/herminettes et d’autres outils tranchants qui leur servaient notamment \u00e0 creuser leurs pirogues.<\/p>\n\n\n

Pour les sportifs, ou pour ceux qui n’ont pas de 4×4, mais les aptitudes physiques, de nombreuses randonn\u00e9es sont possibles sur le volcan. Certaines au d\u00e9part du p\u00f4le touristique pour acc\u00e9der au sommet : donc faire 1400m de d\u00e9nivel\u00e9 positif \u00e0 partir de 2800m pour aller au sommet — donc des sportifs !
J’ai choisi la facilit\u00e9, et quelque chose adapt\u00e9 \u00e0 mes moyens physiques : une “balade” \u00e0 4000m…<\/p>\n\n\n
