Jordsk\u00e6lv er den farligste af alle naturkatastrofer. De fleste d\u00f8dsfald skyldes sammenstyrtende bygninger eller brande.<\/p>\n<\/div>\n

Der forekommer flere millioner jordsk\u00e6lv i verden hvert \u00e5r. Mange af disse registreres dog ikke, fordi de finder sted i afsidesliggende omr\u00e5der eller er meget svage. I gennemsnit forekommer der 18 st\u00f8rre jordsk\u00e6lv og \u00e9t meget kraftigt jordsk\u00e6lv hvert \u00e5r.<\/p>\n

Det seneste store jordsk\u00e6lv fandt sted p\u00e5 \u00f8en Haiti i Vestindien. Den haitianske regering oplyste, at 230.000 mennesker var omkommet, 300.000 var blevet s\u00e5ret, og en million var blevet hjeml\u00f8se.<\/p>\n

Jordsk\u00e6lv forekommer oftest i n\u00e6rheden af store spr\u00e6kker i jordskorpen, der kaldes \u201cforkastninger\u201d. De forekommer ofte i Sydeuropa, hvor to store jordskorpeblokke bev\u00e6ger sig mod hinanden.<\/p>\n

Radarinstrumenter p\u00e5 ESA\u2019s ERS-2- og Envisat-satellitter g\u00f8r det muligt at fastsl\u00e5, om overfladen bev\u00e6ger sig. De kan m\u00e5le bev\u00e6gelsen med en n\u00f8jagtighed p\u00e5 f\u00e5 millimeter.<\/p>\n

Radar kan ogs\u00e5 bruges til at kortl\u00e6gge og vurdere skaderne p\u00e5 bygninger, b\u00e5de om dagen og om natten. Dette er til stor hj\u00e6lp for rednings- og genopbygningshold.<\/p>\n

Der findes stadig ingen pr\u00e6cis metode til at forudsige jordsk\u00e6lv. ESA\u2019s satellitter leverer imidlertid pr\u00e6cise oplysninger, der kan hj\u00e6lpe forskerne i deres arbejde. Data, der er indsamlet gennem mange \u00e5r, bidrager til at forudsige fremtidige jordsk\u00e6lv og afd\u00e6kke skjulte forkastninger.<\/p>","protected":false},"excerpt":{"rendered":"
