Pod oce\u00e1nem planeta d\u00fdch\u00e1. <\/p>\n

Ve v\u011bt\u0161in\u011b p\u0159\u00edpad\u016f se jedn\u00e1 o pomal\u00fd proces. Tektonick\u00e9 desky se od sebe pomalu vzdaluj\u00ed pod\u00e9l mohutn\u00fdch podmo\u0159sk\u00fdch horsk\u00fdch p\u00e1sem. \u0158\u00edk\u00e1me jim st\u0159edooce\u00e1nsk\u00e9 h\u0159bety. Magma stoup\u00e1 na povrch a vypl\u0148uje vznikl\u00e9 dutiny. L\u00e1va se ochlazuje a tvo\u0159\u00ed se nov\u00e1 k\u016fra. Toto je doslova nejv\u011bt\u0161\u00ed hra v planet\u00e1rn\u00edm m\u011b\u0159\u00edtku \u201ePodlaha je l\u00e1va\u201c. <\/p>\n

Teoreticky jsme v\u011bd\u011bli, jak to funguje. U\u010debnice geologie tento p\u0159\u00edb\u011bh vypr\u00e1v\u011bj\u00ed miliony let. Ale nikdy jsme tento proces nepozorovali v re\u00e1ln\u00e9m \u010dase. Ne doopravdy. Ne s kamerami a senzory nam\u00ed\u0159en\u00fdmi p\u0159\u00edmo na m\u00edsto, kde se zem\u011b otev\u00edr\u00e1 jako r\u00e1na. <\/p>\n

Zat\u00edm. <\/p>\n

V Indick\u00e9m oce\u00e1nu m\u011bli v\u00fdzkumn\u00edci \u0161t\u011bst\u00ed. Nasadili cel\u00fd arzen\u00e1l technologick\u00fdch \u0159e\u0161en\u00ed. Akustick\u00e9 transpond\u00e9ry. Tlakom\u011bry. Geodetick\u00e9 maj\u00e1ky. Hydrofony<\/em> jsou stejn\u00e9 \u201epodvodn\u00ed u\u0161i\u201c ur\u010den\u00e9 k poslechu seismick\u00fdch ot\u0159es\u016f. Po instalaci za\u0159\u00edzen\u00ed za\u010dali \u010dekat. <\/p>\n

Dva m\u011bs\u00edce jsou podle lidsk\u00fdch m\u011b\u0159\u00edtek v\u011b\u010dnost. V geologii je to jen okam\u017eik. <\/p>\n

Zem\u011b se pohnula. <\/p>\n

M\u00e9n\u011b ne\u017e \u0161est t\u00fddn\u016f po instalaci za\u0159\u00edzen\u00ed \u0159ada zem\u011bt\u0159esen\u00ed roztrhla h\u0159eben na kusy. Dno oce\u00e1nu se neposunulo; spadlo to \u010dty\u0159i metry. Dvan\u00e1ct stop. Desky se od sebe posunuly o cel\u00fd metr. A pak p\u0159i\u0161el ohniv\u00fd proud. Mo\u0159sk\u00e9 dno zaplavilo sto \u0161edes\u00e1t milion\u016f kub\u00edk\u016f l\u00e1vy. Tolik objem\u016f sk\u00e1ly by sta\u010dilo na stavbu \u0161edes\u00e1ti Velk\u00fdch pyramid v G\u00edze. \u0160edes\u00e1t. <\/p>\n

“\u010cekali jsme, \u017ee zm\u011b\u0159\u00edme mo\u017en\u00e1 n\u011bkolik milimetr\u016f.” <\/p>\n<\/blockquote>\n

Toto je Jean-Yves Roy z Laborato\u0159e planetologie a geodynamiky v Nantes. Vedl studii, jej\u00ed\u017e v\u00fdsledky byly publikov\u00e1ny v \u010dasopise Nature<\/em>. T\u00fdm si myslel, \u017ee uvid\u00ed pohyb o n\u011bkolik palc\u016f. M\u00edsto toho pozorovali celo\u017eivotn\u00ed nahromad\u011bn\u00e9 vys\u00eddlen\u00ed, ke kter\u00e9mu do\u0161lo b\u011bhem jednoho brut\u00e1ln\u00edho v\u00edkendu. T\u00e9m\u011b\u0159 \u010dty\u0159icet let tektonick\u00e9ho driftu se odehr\u00e1lo p\u0159es noc. <\/p>\n

To je d\u016fle\u017eit\u00e9, proto\u017ee to vyvrac\u00ed m\u00fdtus \u201epomal\u00e9ho a stabiln\u00edho\u201c. Desky neklou\u017eou jako puky po ledu. Zaseknou se. Akumuluj\u00ed nap\u011bt\u00ed. A pak praskly s ranou. <\/p>\n

Zde je hlub\u0161\u00ed z\u00e1hada, kterou vy\u0159e\u0161ili. <\/p>\n

V\u011bdci se v\u017edy zaj\u00edmali, jak se tyto zlomy pohybuj\u00ed, ani\u017e by zp\u016fsobily ot\u0159esy Zem\u011b. Existuje n\u011bco jako \u201easeismick\u00fd posun\u201c. Je to o\u0161emetn\u00fd term\u00edn. To znamen\u00e1, \u017ee se kameny pohybuj\u00ed, t\u00edraj\u00ed o sousedn\u00ed vrstvy, ale nedoch\u00e1z\u00ed k zem\u011bt\u0159esen\u00ed. \u017d\u00e1dn\u00fd v\u00fdbuch. \u017d\u00e1dn\u00e9 ot\u0159esy. Jen tich\u00fd skluz. <\/p>\n

Je toto tich\u00e9 klouz\u00e1n\u00ed zp\u016fsobeno magmatem? Nev\u011bd\u011bli jsme. <\/p>\n

Nov\u00e1 data \u0159\u00edkaj\u00ed ano. <\/p>\n

Zlomov\u00e1 linie se posunula asi o dva metry. Zem\u011bt\u0159esen\u00ed? Vysv\u011btluj\u00ed pouze deset a\u017e dvacet centimetr\u016f tohoto posunut\u00ed. Co zbytek dvoumetrov\u00e9ho skoku? Stalo se to v tichosti. Pot\u00e9, co kameny ji\u017e praskly. <\/p>\n

Nejde jen o to, \u017ee posun existuje. Nast\u00e1v\u00e1 v okam\u017eiku, kdy doraz\u00ed magma.<\/em> <\/p>\n

Hannah F. Mark, kter\u00e1 se na studii nepod\u00edlela, ale na Kolumbijsk\u00e9 univerzit\u011b ji pozorn\u011b sleduje, uhodila h\u0159eb\u00ed\u010dek na hlavi\u010dku. Posun je v p\u0159\u00ed\u010dinn\u00e9 souvislosti s taven\u00edm hornin. <\/p>\n

Pro\u010d se t\u00edm v\u011bci m\u011bn\u00ed? <\/p>\n

Proto\u017ee to vysv\u011btluje ticho ve velk\u00fdch hloubk\u00e1ch oce\u00e1nu. St\u0159edooce\u00e1nsk\u00e9 h\u0159ebeny by m\u011bly b\u00fdt hlu\u010dn\u011bj\u0161\u00ed. Pokud byste se\u010detli v\u0161echny pohyby tal\u00ed\u0159\u016f, \u010dekali byste neust\u00e1l\u00e9 chv\u011bn\u00ed. M\u00edsto toho n\u011bkte\u0159\u00ed z nich ti\u0161e jdou do propasti. P\u0159\u00edli\u0161 tich\u00fd na to, abych si jich v\u0161iml. <\/p>\n

Pokud nesn\u00ed\u017e\u00edte sv\u016fj poslechov\u00fd p\u0159\u00edsp\u011bvek na sam\u00e9 dno sv\u011bta a nebudete \u010dekat. <\/p>\n
