Maailmas on umbes 1 500 aktiivset vulkaani, millest igal aastal purskab umbes 50. Enamik neist vulkaanidest asub Vaikse ookeani \u00fcmbruses \u2013 v\u00f6\u00f6ndis, mida tuntakse Vaikse ookeani \u201ctulekeelena\u201d. Ka Euroopas on oma vulkaanid, nagu Etna ja Vesuvius, mis on ajaloo jooksul mitu korda purskanud.<\/p>\n<\/div>\n

V\u00e4hemalt 500 miljonit inimest elab aktiivse vulkaani l\u00e4hedal. Purskamise korral v\u00f5ivad l\u00e4hedal asuvad piirkonnad kattuda tuhaga ja tulikuuma laavaga.<\/p>\n

P\u00f5llud ja hooned v\u00f5ivad j\u00e4\u00e4da maapinna alla. M\u00fcrgised gaasid, h\u00f5\u00f5guvad tuhapilved v\u00f5i mudavoolud v\u00f5ivad tappa k\u00f5ik, kes nende teele satuvad. \u00d5nneks aitavad satelliidid n\u00fc\u00fcd kindlaks teha k\u00f5ige ohtlikumad vulkaanid.<\/p>\n

ESA satelliidid Envisat ja ERS-2 uurivad vulkaane mitmel erineval viisil. Kaamerad j\u00e4\u00e4dvustavad laavavoolusid ja tuhapilvi. Infrapunaseadmed tuvastavad pinnale t\u00f5usvat kuuma laavat.<\/p>\n

Radar suudab j\u00e4lgida vulkaani \u201chingamist\u201d, kui selle sees liigub sulakivim. Juba m\u00f5ne millimeetri suurune pinnapaisumine v\u00f5ib viidata survele, mis koguneb enne purskamist. Muud andurid tuvastavad \u00f5hku eralduvaid gaase ja osakesi.<\/p>\n

Sellised andmed p\u00e4\u00e4stavad elusid ja aitavad ennustada, millal toimub j\u00e4rgmine vulkaanipurskamine. Kahjustatud piirkondade satelliitkaardid aitavad kaasa ka p\u00e4\u00e4ste- ja taastamist\u00f6\u00f6dele.<\/p>","protected":false},"excerpt":{"rendered":"
