Geoloog Siim Veski r\u00e4\u00e4kis “Ringvaates”, et \u00fcle 50 protsendi suurtest \u00e4kktulvadest toimub Aasias iga kolme-nelja aasta tagant ja selle tingib Aasia seismiline piirkond. Veski s\u00f5nul j\u00f5udis Nepalis toimunud \u00e4kktulv inimesteni seitsme minutiga.<\/p>\n
“Nepalis toimus \u00e4kktulv sellisel alal, mis oli monitooringu alt v\u00e4lja, see oli pime koht. Nepalis on k\u00fcll \u00fcleval monitooringus\u00fcsteem, mida j\u00e4lgitakse, aga pigem eeldatakse, et see juhtub mussoonperioodil, \u00fctles geoloogiateadlane Siim Veski. “Kohutav s\u00fcndmus, aga sellised s\u00fcndmused ei l\u00f5pe.”<\/p>\n
Algul arvati, et tegemist on maav\u00e4rinaga, sest see on maav\u00e4rinaohtlik piirkond, seej\u00e4rel m\u00f5eldi, et suur j\u00e4\u00e4liustik kukkus alla. “Arvati ka, et mingi j\u00e4\u00e4j\u00e4rv paiskus allavoolu, l\u00f5puks tuli v\u00e4lja, et see on kaskaads\u00fcndmus. Toimus maalihe, mis t\u00f5mbas endaga kaasa liustiku. Maalihe kukkus umbes \u00fche kilomeetri k\u00f5rguselt. J\u00e4\u00e4 pulbristus ja kogu mass paiskus alla m\u00f6\u00f6da orgu,” selgitas Veski. “On hinnatud, et liustik oli 5200 meetri k\u00f5rgusel.”<\/p>\n
Nepalis esimese varingu ja inimesteni j\u00f5udmise vahe oli seitse minutit. “P\u00f5him\u00f5tteliselt ei j\u00f5ua midagi teha. \u0160veitsis aasta tagasi mais kestis kogu s\u00fcndmus kuu aega. J\u00f5uti \u00e4ra evakueerida k\u00f5ik k\u00fclad, lehmad, kitsed. M\u00e4gi hakkas vajuma pool meetrit p\u00e4evas. Kui see toimub aeglaselt, on v\u00f5imalik k\u00f5ike ette v\u00f5tta, aga kui \u00e4kki, siis pole midagi teha,” nentis geoloog.<\/p>\n
Nepalis juhtunu oli 25 aasta suurimaid \u00e4kktulvasid. “Aasia regioonis on iga kolme-nelja aasta tagant olnud mingi korralik s\u00fcndmus ja \u00fcle 50 protsendi neist s\u00fcndmustest toimub Aasias, \u00fclej\u00e4\u00e4nud s\u00fcndmused jagunevad \u00fcle terve maailma laiali.”<\/p>\n
Selle tingib seismiline piirkond, k\u00f5rged m\u00e4ed, liustikud, vulkaanid, maav\u00e4rinad. “See k\u00f5ik tekitab sellise situatsiooni, et \u00e4kktulvad on v\u00f5imalikud.”<\/p>\n
Kliimasoojenemine toob kaasa igij\u00e4\u00e4 sulamise m\u00e4etippudel. “Igij\u00e4\u00e4 on p\u00f5him\u00f5tteliselt nagu liim liustiku ja kalju vahel ja kui seda liimi enam ei ole, siis hakkavad massid liikuma. Sellest ei teata, sest igij\u00e4\u00e4 pindmine kiht v\u00f5ib sulada v\u00e4ga kiiresti, aga j\u00e4\u00e4 s\u00fcgavam sulamine ei paista v\u00e4lja,” selgitas Veski.<\/p>\n","protected":false},"excerpt":{"rendered":"Geoloog Siim Veski r\u00e4\u00e4kis “Ringvaates”, et \u00fcle 50 protsendi suurtest \u00e4kktulvadest toimub Aasias iga kolme-nelja aasta tagant ja…\n","protected":false},"author":2,"featured_media":267106,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[5],"tags":[102894,26,27,37,33,35,34,36,31,32,21,28,29,8146,19,25,103495,23,24,22,20,30],"class_list":["post-267105","post","type-post","status-publish","format-standard","has-post-thumbnail","category-uldised-uudised","tag-akktulv","tag-breaking-news","tag-breakingnews","tag-ee","tag-eesti","tag-eesti-keel","tag-estonia","tag-estonian","tag-featured-news","tag-featurednews","tag-headlines","tag-latest-news","tag-latestnews","tag-nepal","tag-news","tag-populaarseimad-lood","tag-siim-veski","tag-top-stories","tag-topstories","tag-uldised-uudised","tag-uudised","tag-viimased-uudised"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ee\/117204399348790762","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/posts\/267105","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/comments?post=267105"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/posts\/267105\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/media\/267106"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/media?parent=267105"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/categories?post=267105"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/tags?post=267105"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
