\u017de drugi\u010d v tem letu je izbruh vulkana na Islandiji povzro\u010dil kaos po ve\u010djem delu Evrope. Te\u017eave so povzro\u010dili oblaki pepela, ki so se dvignili ve\u010d kilometrov visoko v zrak. Za Islandce, ki \u017eivijo v bli\u017eini vulkanov, se je \u017eivljenje drasti\u010dno spremenilo. Plast rjavega pepela prekriva hi\u0161e, ceste in polja. Vendar so se ogromni oblaki raz\u0161irili tudi tiso\u010de kilometrov po Evropi, zaradi \u010desar so morala \u0161tevilna letala ostati na tleh.<\/p>\n<\/div>\n

Prvi izbruh se je za\u010del marca 2010, ko je vulkan Eyjafjallaj\u00f6kull za\u010del izmetavati oblake pare in pepela. V naslednjih nekaj mesecih so bili odpovedani tiso\u010di letov, saj so se drobni delci raz\u0161irili po Evropi. Ko se je izbruh kon\u010dal, so se leti vrnili v normalno stanje. Nato je 21. maja 2011 vulkan Gr\u00edmsv\u00f6tn za\u010del izmetavati pepel visoko v atmosfero. Na sre\u010do se je ta izbruh, \u010deprav je bil mo\u010dnej\u0161i od prej\u0161njega, precej hitro umiril. Do konca maja so se leti vrnili v normalno stanje.<\/p>\n

Ena od glavnih te\u017eav letalskih dru\u017eb in vlad med tak\u0161nimi izbruhi je zagotoviti varnost potnikov. Ko letalo leti skozi vulkanski oblak, delci pepela vstopijo v reaktivne motorje in lahko povzro\u010dijo okvaro motorja. Pepel lahko tudi hudo po\u0161koduje zunanjost letala. Zato je nujno najti na\u010din za spremljanje gibanja oblaka in dolo\u010ditev njegove debeline.<\/p>\n

Na sre\u010do lahko sateliti v zemeljski orbiti, kot je Envisat agencije ESA, posnamejo slike oblakov pepela. Prav tako lahko zaznavajo pline, kot je \u017eveplov dioksid, ki so bili izvr\u017eeni visoko v atmosfero in pogosto dose\u017eejo vi\u0161ine, na katerih potekajo redni leti. Podatki se po\u0161ljejo svetovalnim centrom za vulkanski pepel, ki ocenijo morebitno nevarnost za letalstvo in izdajo opozorila.<\/p>","protected":false},"excerpt":{"rendered":"
