Podle nov\u00e9 studie ESA zem\u011bt\u0159esen\u00ed na Sumat\u0159e z 26. prosince 2004 nejen\u017ee zpusto\u0161ilo obrovsk\u00e9 \u00fazem\u00ed, ale tak\u00e9 m\u00edrn\u011b zm\u011bnilo gravita\u010dn\u00ed pole v t\u00e9to oblasti.<\/p>\n<\/div>\n

Kdy\u017e se b\u011bhem zem\u011bt\u0159esen\u00ed posunulo dno Indick\u00e9ho oce\u00e1nu pod\u00e9l 1000 km dlouh\u00e9 zlomov\u00e9 linie, vznikl tak 6 metr\u016f vysok\u00fd v\u00fd\u010dn\u011blek. Tento obrovsk\u00fd pohyb hornin okam\u017eit\u011b zm\u011bnil m\u00edstn\u00ed gravita\u010dn\u00ed podm\u00ednky.<\/p>\n

To nen\u00ed nic neobvykl\u00e9ho. Mapy vytvo\u0159en\u00e9 na z\u00e1klad\u011b satelitn\u00edch dat ukazuj\u00ed, \u017ee gravita\u010dn\u00ed s\u00edla se li\u0161\u00ed m\u00edsto od m\u00edsta. Jedn\u00edm z d\u016fvod\u016f je rotace Zem\u011b. Jak se planeta ot\u00e1\u010d\u00ed, vyklenuje se v oblasti rovn\u00edku. Jeliko\u017e je Zem\u011b v rovn\u00edkov\u00e9 oblasti o 42 km \u0161ir\u0161\u00ed, je tam gravita\u010dn\u00ed s\u00edla slab\u0161\u00ed ne\u017e na p\u00f3lech.<\/p>\n

Vliv na to maj\u00ed tak\u00e9 vysok\u00e9 hory, hlubok\u00e9 oce\u00e1nsk\u00e9 p\u0159\u00edkopy a r\u016fzn\u00e9 druhy hornin v nitru Zem\u011b. Dokonce i p\u0159\u00edlivy a odlivy, oce\u00e1nsk\u00e9 proudy a t\u00e1n\u00ed ledov\u00fdch \u0161t\u00edt\u016f zp\u016fsobuj\u00ed kol\u00eds\u00e1n\u00ed hodnoty gravita\u010dn\u00ed s\u00edly.<\/p>\n

V sou\u010dasn\u00e9 dob\u011b je m\u011b\u0159en\u00ed takov\u00fdchto nepatrn\u00fdch zm\u011bn gravita\u010dn\u00edho pole obt\u00ed\u017en\u00e9, ale to se zm\u011bn\u00ed s p\u0159\u00ed\u0161t\u00edm rokem, kdy bude vypu\u0161t\u011bna sonda ESA Gravity Field and Ocean Circulation Explorer (GOCE).<\/p>\n

Tato citliv\u00e1 kosmick\u00e1 lo\u010f bude velmi podrobn\u011b zkoumat gravitaci. P\u0159i pr\u016fletu oblastmi se siln\u011bj\u0161\u00edm a slab\u0161\u00edm gravita\u010dn\u00edm polem se bude kosmick\u00e1 lo\u010f pohybovat nahoru a dol\u016f a jej\u00ed p\u0159\u00edstroje budou zaznamen\u00e1vat zm\u011bny gravita\u010dn\u00edho pole pod\u00e9l jej\u00ed dr\u00e1hy.<\/p>\n

D\u00edky tomu budou v\u011bdci moci m\u011b\u0159it, jak\u00e9 mno\u017estv\u00ed materi\u00e1lu se p\u0159esouv\u00e1 \u2013 a\u0165 u\u017e n\u00e1hle p\u0159i zem\u011bt\u0159esen\u00ed, nebo postupn\u011b, jako je tomu v p\u0159\u00edpad\u011b taj\u00edc\u00edho ledov\u00e9ho \u0161t\u00edtu. Tyto \u00fadaje dokonce pomohou odhalit zm\u011bny v oce\u00e1nsk\u00e9 cirkulaci, kter\u00e9 souvisej\u00ed se zm\u011bnou klimatu.<\/p>","protected":false},"excerpt":{"rendered":"
