Exist\u0103 aproximativ 1.500 de vulcani activi, dintre care circa 50 erup \u00een fiecare an. Majoritatea acestor vulcani se afl\u0103 \u00een jurul Oceanului Pacific \u2013 o centur\u0103 cunoscut\u0103 sub numele de \u201cInelul de Foc\u201d al Pacificului. Europa are propriii s\u0103i vulcani, precum Etna \u0219i Vezuviul, care au erupt de multe ori de-a lungul istoriei.<\/p>\n<\/div>\n

Cel pu\u021bin 500 de milioane de oameni locuiesc \u00een apropierea unui vulcan activ. C\u00e2nd are loc o erup\u021bie, zonele din apropiere pot fi acoperite de cenu\u0219\u0103 \u0219i de lav\u0103 incandescent\u0103.<\/p>\n

C\u00e2mpurile \u0219i cl\u0103dirile pot fi \u00eengropate. Gazele otr\u0103vitoare, norii de cenu\u0219\u0103 incandescent\u0103 sau curgerile de noroi pot ucide pe oricine se afl\u0103 \u00een calea lor. Din fericire, sateli\u021bii contribuie acum la identificarea celor mai periculo\u0219i vulcani.<\/p>\n

Sateli\u021bii Envisat \u0219i ERS-2 ai ESA studiaz\u0103 vulcanii \u00een numeroase moduri diferite. Camerele de filmat surprind curgerile de lav\u0103 \u0219i norii de cenu\u0219\u0103. Instrumentele cu infraro\u0219u detecteaz\u0103 lava fierbinte care se ridic\u0103 la suprafa\u021b\u0103.<\/p>\n

Radarul poate observa \u201crespira\u021bia\u201d unui vulcan pe m\u0103sur\u0103 ce roca topit\u0103 se mi\u0219c\u0103 \u00een interiorul acestuia. O umflare a suprafe\u021bei de doar c\u00e2\u021biva milimetri poate indica acumularea de presiune \u00eenaintea unei erup\u021bii. Al\u021bi senzori identific\u0103 gazele \u0219i particulele eliberate \u00een aer.<\/p>\n

Aceste date salveaz\u0103 vie\u021bi \u0219i ajut\u0103 la previzionarea momentului \u00een care va avea loc urm\u0103toarea erup\u021bie. H\u0103r\u021bile satelitare ale zonelor afectate contribuie, de asemenea, la opera\u021biunile de salvare \u0219i la eforturile de reconstruc\u021bie.<\/p>","protected":false},"excerpt":{"rendered":"
