Nj\u00eb zbulim i ri shkencor po rishkruan historin\u00eb gjeologjike t\u00eb Bermud\u00ebs dhe po ofron nj\u00eb shpjegim t\u00eb qart\u00eb p\u00ebr nj\u00eb enigm\u00eb q\u00eb ka intriguar studiuesit prej dekadash: pse ishulli nuk u fundos edhe pse vullkanet e tij jan\u00eb shuar prej miliona vitesh.<\/p>\n
Sipas nj\u00eb studimi t\u00eb publikuar n\u00eb revist\u00ebn Geophysical Research Letters, shkenc\u00ebtar\u00ebt kan\u00eb identifikuar nj\u00eb struktur\u00eb t\u00eb pazakont\u00eb shk\u00ebmbore n\u00ebn shtratin e oqeanit, e cila vepron si nj\u00eb \u201cmb\u00ebshtetje natyrore\u201d p\u00ebr Bermud\u00ebn. N\u00eb kushte normale, ishujt vullkanik\u00eb fillojn\u00eb t\u00eb zhyten gradualisht pasi aktiviteti magmatik ndalon dhe pllaka tektonike largohet nga burimi i nxeht\u00ebsis\u00eb s\u00eb mantelit.<\/p>\n
N\u00eb rastin e Bermud\u00ebs, kjo r\u00ebnie nuk ka ndodhur. Studiuesit zbuluan nj\u00eb shtres\u00eb shk\u00ebmbore rreth 20 kilometra t\u00eb trash\u00eb, m\u00eb pak t\u00eb dendur se materialet p\u00ebrreth, e vendosur midis kores oqeanike dhe mantelit. Nj\u00eb struktur\u00eb e till\u00eb nuk \u00ebsht\u00eb v\u00ebrejtur m\u00eb par\u00eb n\u00eb zona t\u00eb ngjashme.<\/p>\n
Ekipi k\u00ebrkimor, i drejtuar nga sizmiologu William Frazer, analizoi val\u00ebt sizmike t\u00eb 396 t\u00ebrmeteve t\u00eb larg\u00ebta. K\u00ebto val\u00eb, duke kaluar n\u00ebp\u00ebr Tok\u00eb, u shfryt\u00ebzuan p\u00ebr t\u00eb krijuar nj\u00eb imazh t\u00eb detajuar t\u00eb shtresave shk\u00ebmbore deri n\u00eb rreth 50 kilometra thell\u00ebsi n\u00ebn ishull. Pamjet zbuluan nj\u00eb \u201cshtes\u00eb\u201d shk\u00ebmbore q\u00eb ndryshon nga struktura tipike e kores oqeanike.<\/p>\n
Bermuda ndodhet mbi nj\u00eb ngritje oqeanike, ku shtrati i detit \u00ebsht\u00eb rreth 500 metra m\u00eb i lart\u00eb se zonat p\u00ebrreth. Sipas studiuesve, shp\u00ebrthimet e fundit vullkanike, rreth 31 milion\u00eb vite m\u00eb par\u00eb, mund t\u00eb ken\u00eb shtyr\u00eb materiale nga manteli drejt kores, t\u00eb cilat u ftoh\u00ebn dhe u ngurt\u00ebsuan, duke krijuar k\u00ebt\u00eb shtres\u00eb mbajt\u00ebse.<\/p>\n
Zbulimi sugjeron se ishulli ka mbetur i ngritur fal\u00eb k\u00ebsaj strukture t\u00eb brendshme, pavar\u00ebsisht munges\u00ebs s\u00eb aktivitetit vullkanik p\u00ebr miliona vite. Nd\u00ebrkoh\u00eb, shkenc\u00ebtar\u00ebt theksojn\u00eb se nuk ka shenja t\u00eb rrezikut vullkanik aktiv n\u00ebn Bermud\u00eb.<\/p>\n
Ky studim jo vet\u00ebm q\u00eb hedh drit\u00eb mbi formimin e Bermud\u00ebs, por sfidon edhe modelet tradicionale mbi m\u00ebnyr\u00ebn se si evoluojn\u00eb ishujt vullkanik\u00eb n\u00eb koh\u00eb, duke treguar se n\u00ebn sip\u00ebrfaqe mund t\u00eb fshihen mekanizma shum\u00eb m\u00eb kompleks\u00eb sesa mendohej m\u00eb par\u00eb.<\/p>\n","protected":false},"excerpt":{"rendered":"
