Forskarna kan \u00e4nnu inte f\u00f6ruts\u00e4ga katastrofala jordb\u00e4vningar. Satellittekniken kan dock vara till stor hj\u00e4lp f\u00f6r r\u00e4ddningspersonal efter en stor jordb\u00e4vning, s\u00e5som den som drabbade \u00f6n Haiti den 12 januari. Jordb\u00e4vningen, som hade en magnitud p\u00e5 7, drabbade Haitis huvudstad Port-au-Prince och omgivande omr\u00e5den och orsakade tusentals d\u00f6dsfall samt omfattande skador p\u00e5 byggnader.<\/p>\n<\/div>\n

Befintliga kartor blir pl\u00f6tsligt inaktuella efter en s\u00e5dan f\u00f6r\u00f6dande h\u00e4ndelse, vilket g\u00f6r livet \u00e4nnu sv\u00e5rare f\u00f6r hj\u00e4lparbetarna p\u00e5 plats. Med hj\u00e4lp av satellitbilder kan man dock snabbt f\u00e5 fram aktuella bilder av de drabbade omr\u00e5dena.<\/p>\n

I fallet med Haiti fanns snart optiska bilder och radarbilder fr\u00e5n rymden tillg\u00e4ngliga. Radarsatelliter har f\u00f6rdelen att de kan se igenom moln och avbilda marken p\u00e5 natten. Radarbilder kan anv\u00e4ndas f\u00f6r att identifiera faror som jordskred, vilka kan utl\u00f6sas av jordb\u00e4vningar. P\u00e5 l\u00e5ng sikt kan radardata \u00e4ven anv\u00e4ndas f\u00f6r att kartl\u00e4gga f\u00f6r\u00e4ndringar i ytstrukturen och hj\u00e4lpa forskare att f\u00f6rst\u00e5 s\u00e5dana h\u00e4ndelser.<\/p>\n

Bilder fr\u00e5n en internationell satellitflotta, d\u00e4ribland ESA:s ERS-2 och Envisat, tillhandah\u00e5lls kostnadsfritt till r\u00e4ddningsstyrkorna i Haiti. Bilder som tagits omedelbart efter katastrofen anv\u00e4nds f\u00f6r att skapa n\u00f6dkartor \u00f6ver omr\u00e5det. Dessa kartor anv\u00e4nds f\u00f6r att identifiera de omr\u00e5den som drabbats h\u00e5rdast och f\u00f6r att kartl\u00e4gga framkomliga v\u00e4gar f\u00f6r hj\u00e4lparbetare och r\u00e4ddningspersonal. De hj\u00e4lper ocks\u00e5 till att lokalisera omr\u00e5den som \u00e4r l\u00e4mpliga f\u00f6r att inr\u00e4tta hj\u00e4lpl\u00e4ger, d\u00e4r medicinsk v\u00e5rd och skydd kan tillhandah\u00e5llas.<\/p>","protected":false},"excerpt":{"rendered":"
