\u00a0Prezicerea cutremurelor a fost mereu o preocupare major\u0103 a omenirii.<\/p>\n
O inginer\u0103 din Marghita, Kovacs Erika Iuliana, sus\u0163ine c\u0103 a\u00a0descoperit o metod\u0103 sigur\u0103 de prezicere a cutremurelor. Cu c\u00e2teva ore \u00eenainte de cutremure, c\u00e2nd tensiunea acumulat\u0103 \u00eentre pl\u0103cile tectonice dep\u0103\u015fe\u015fte o valoare critic\u0103, pl\u0103cile tectonice \u00eencep s\u0103 vibreze \u015fi emit unde sonore, infrasunete cu frecven\u0163a \u00eentre 4,5 \u2013 5 Hz (Hertz). Aceste infrasunete se transmit pe sub p\u0103m\u00e2nt\u00a0 \u015fi nu pot fi percepute de urechea uman\u0103, care aude numai sunete cu frecven\u0163a \u00eentre 20 Hz \u2013 20000 Hz, dar sunt percepute de diverse specii de animale, care au un comportament diferit \u00eenainte de un cutremur mare.<\/span><\/div>\n<\/div>\n
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Intensitatea infrasunetelor seismice ( \u00een\u00a0<\/span>W\/m\u00b2<\/span>\u00a0) \u0219i nivelul sunetului ( \u00een dB \u2013 decibeli ) cresc odat\u0103 cu tensiunea acumulat\u0103 \u00eentre pl\u0103cile tectonice. Intensitatea cutremurelor este direct propor\u021bional\u0103 cu intensitatea infrasunetelor preseismice \u0219i nivelul sunetului.\u00a0 Cutremurele mari sunt precedate de infrasunete seismice de intensitate mare \u0219i cu nivelul sunetului mare. Prin crearea unei re\u021bele care \u00eenregistreaz\u0103 infrasunetele preseismice se poate determina epicentrul viitorului cutremur \u0219i intensitatea lui.\u00a0<\/span><\/div>\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span>\u00a0\u00a0 Cum infrasunetele preseismice se transmit pe sub p\u0103m\u00e2nt, nu sunt detectate de microbarometrele folosite de seismologi, deoarece microbarometrele monitorizeaz\u0103 fluctua\u021biile infrasonice ale atmosferei. \u00cen momentul declan\u0219\u0103rii cutremurelor puternice, intensitatea infrasunetelor seismice cre\u0219te brusc \u0219i atinge valori suficient de mari pentru ca infrasunetele s\u0103 fie detectate \u0219i \u00een atmosfer\u0103 de c\u0103tre microbarometre, \u00eens\u0103 intervalul de timp pentru alertarea popula\u021biei este foarte\u00a0 scurt.<\/span>
\n<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Senzorii trebuie amplasa\u021bi sub p\u0103m\u00e2nt, aceast\u0103 amplasare oferind posibilitatea detect\u0103rii infrasunetelor preseismice cu c\u00e2teva ore \u00eenainte de producerea cutremurelor. Numai \u00een acest mod popula\u021bia poate fi alertat\u0103 la timp, evit\u00e2nd pierderile umane, a precizat pentru Rador Kovacs Erika Iuliana.<\/div>\n
