Aceste cutremure pot avea loc cu o regularitate de ceasornic \u0219i au aproape \u00eentotdeauna aceea\u0219i magnitudine.<\/p>\n

Un nou studiu ofer\u0103 un posibil r\u0103spuns, potrivit Science Alert<\/a>.<\/p>\n

Aceste falii oceanice de transformare, a\u0219a cum sunt cunoscute, sunt \u00eenconjurate de zone de barier\u0103. Cercet\u0103torii din SUA \u0219i Canada au demonstrat c\u0103 acestea ac\u021bioneaz\u0103 ca ni\u0219te \u201efr\u00e2ne\u201d naturale pentru activitatea seismic\u0103.<\/p>\n

Un proces cunoscut sub numele de \u00eent\u0103rire prin dilatare are loc atunci c\u00e2nd apa de mare se infiltreaz\u0103 ad\u00e2nc \u00een roc\u0103. Acest proces protejeaz\u0103 aceste sec\u021biuni de falie de violen\u021ba cutremurelor mai mari.<\/p>\n

Prin dezv\u0103luirea secretelor acestor falii neobi\u0219nuit de previzibile, speran\u021ba este c\u0103 modelele seismice pot fi \u00eembun\u0103t\u0103\u021bite \u00een general.<\/p>\n

Ce au observat oamenii de \u0219tiin\u021b\u0103<\/h2>\n

Cercet\u0103torii au studiat date din dou\u0103 sec\u021biuni de-a lungul faliei de transformare Gofar. Aceasta este o depresiune subacvatic\u0103 extins\u0103 care marcheaz\u0103 grani\u021ba dintre pl\u0103cile tectonice Pacific \u0219i Nazca, la vest de Ecuador \u0219i ad\u00e2nc sub Oceanul Pacific.<\/p>\n

Aceste pl\u0103ci se freac\u0103 una de alta cu o vitez\u0103 de aproximativ 140 de milimetri pe an. Falia a generat un cutremur regulat de magnitudine \u0219ase la fiecare cinci sau \u0219ase ani de c\u00e2nd a \u00eenceput \u00eenregistrarea complet\u0103 a datelor \u00een 1995.<\/p>\n

\u00cen dou\u0103 experimente separate, dispozitive seismometrice de fund oceanic au fost amplasate direct pe fundul m\u0103rii pentru a urm\u0103ri mi\u0219carea. Aceste instrumente au captat detaliile a zeci de mii de cutremure mici din jurul a dou\u0103 cutremure majore.<\/p>\n

Analiza datelor a ar\u0103tat c\u0103 cele dou\u0103 segmente ale faliei Gofar, fiecare cu o zon\u0103 de barier\u0103, s-au cutremurat \u00een mod similar.<\/p>\n

M\u0103sur\u0103torile au ar\u0103tat c\u0103 zonele de barier\u0103 sunt, de fapt, re\u021bele complexe de falii mici. Acestea absorb numeroasele \u0219ocuri minore care preced marile cutremure.<\/p>\n

Modul \u00een care se produc unele cutremure<\/h2>\n

C\u00e2nd au loc cutremurele principale, roca umplut\u0103 cu fluid din jurul acestor zone tampon se deplaseaz\u0103 \u0219i se extinde. Mai mult\u0103 ap\u0103 se revars\u0103 \u00een goluri.<\/p>\n

Acest lucru creeaz\u0103 schimb\u0103ri de presiune care determin\u0103 \u201eblocarea\u201d rocii \u0219i \u00eempiedic\u0103 alunecarea \u00een continuare, \u00eempiedic\u00e2nd efectiv amplificarea cutremurului.<\/p>\n

De\u0219i p\u00e2n\u0103 \u00een prezent a fost analizat\u0103 doar o singur\u0103 falie specific\u0103 \u00een cadrul acestui studiu, zonele de barier\u0103 precum cele din jurul faliilor Gofar ar putea afecta \u0219i alte falii.<\/p>\n

Acest lucru ar necesita acela\u0219i tip de fracturare complex\u0103 \u0219i infiltrare a apei de mare observate \u00een acest studiu.<\/p>\n","protected":false},"excerpt":{"rendered":"
