Les scientifiques ne sont pas encore capables de pr\u00e9dire les tremblements de terre catastrophiques. Cependant, la technologie satellitaire peut apporter une grande aide aux \u00e9quipes de secours apr\u00e8s un important s\u00e9isme, comme celui qui a frapp\u00e9 l\u2019\u00eele de Ha\u00efti le 12 janvier. La magnitude 7 a frapp\u00e9 la capitale ha\u00eftienne de Port-au-Prince et ses environs, causant des milliers de victimes et une destruction massive des maisons et b\u00e2timents.<\/p>\n<\/div>\n

Les cartes existantes deviennent subitement obsol\u00e8tes apr\u00e8s un tel ph\u00e9nom\u00e8ne d\u00e9vastateur, rendant la t\u00e2che des \u00e9quipes au sol encore plus difficile. Cependant, l\u2019utilisation des images satellites a permis d\u2019obtenir rapidement des vues des zones touch\u00e9es par le s\u00e9isme.<\/p>\n

Pour Ha\u00efti, des images optiques et radar prises depuis l\u2019espace ont pu \u00eatre rapidement obtenues. Les satellites radar pr\u00e9sentent l\u2019avantage de pouvoir voir \u00e0 travers les nuages et de prendre des images pendant la nuit. L\u2019imagerie radar peut servir \u00e0 identifier les dangers, comme les glissements de terrain susceptibles d\u2019\u00eatre provoqu\u00e9s par un s\u00e9isme. A long terme, les donn\u00e9es radar peuvent \u00e9galement servir \u00e0 cartographier les changements survenus \u00e0 la surface de la Terre et aider les scientifiques \u00e0 comprendre de tels ph\u00e9nom\u00e8nes.<\/p>\n

Les images captur\u00e9es par une flotte de satellites internationale, et notamment les satellites ERS-2 et Envisat de l\u2019ESA, sont fournies gratuitement aux \u00e9quipes d\u2019intervention en Ha\u00efti. Les images prises imm\u00e9diatement apr\u00e8s le s\u00e9isme servent \u00e0 cr\u00e9er des cartes d\u2019urgence de la r\u00e9gion. Ces cartes permettent d\u2019identifier les zones les plus touch\u00e9es et de localiser les routes praticables pour les \u00e9quipes de sauvetage et de secours. Elles permettent \u00e9galement de rep\u00e9rer les zones les mieux adapt\u00e9es \u00e0 l\u2019\u00e9tablissement de camps, o\u00f9 les populations peuvent esp\u00e9rer obtenir des soins m\u00e9dicaux et trouver un abri.<\/p>","protected":false},"excerpt":{"rendered":"
