Studiul, publicat \u00een revista Science, citat\u0103 de CNN<\/a>, analizeaz\u0103 date seismice colectate \u00eentre 2008 \u0219i 2025 \u00een zona muntelui Mantap, unde Coreea de Nord a efectuat \u0219ase teste nucleare \u00eentre 2006 \u0219i 2017.<\/p>\n

Ultimul test a fost \u0219i cel mai puternic. Explozia a avut o putere estimat\u0103 la aproximativ 160 de kilotone \u0219i a provocat un cutremur cu magnitudinea 6,3. Cercet\u0103torii consider\u0103 c\u0103 explozia ar fi provocat \u0219i pr\u0103bu\u0219irea unei structuri subterane.<\/p>\n

Teste nucleare sau ap\u0103 infiltrat\u0103 \u00een subteran?<\/h2>\n

\u00cen mod normal, exploziile nucleare subterane pot declan\u0219a mici cutremure, \u00eens\u0103 activitatea seismic\u0103 scade de regul\u0103 rapid dup\u0103 explozie. \u00cen cazul muntelui Mantap, cercet\u0103torii au observat exact opusul.<\/p>\n

\u00centre 2008 \u0219i 2025 au fost identificate 1.399 de cutremure \u00een regiune. Cele mai multe au avut magnitudini \u00eentre 2 \u0219i 3, \u00eens\u0103 frecven\u021ba lor a crescut \u00een timp, mai ales dup\u0103 testul nuclear din 2017. Zona era considerat\u0103 anterior una cu activitate tectonic\u0103 foarte redus\u0103. Peninsula Coreean\u0103 se afl\u0103 pe o crust\u0103 continental\u0103 relativ stabil\u0103, departe de principalele limite dintre pl\u0103cile tectonice.<\/p>\n

Echipa de cercet\u0103tori a identificat \u00eens\u0103 mai multe falii vechi \u00een apropierea muntelui Mantap. Aceste fracturi din scoar\u021ba terestr\u0103 ar fi putut fi activate de exploziile subterane. O posibil\u0103 explica\u021bie este c\u0103 explozia din 2017 a fracturat o cantitate mare de roc\u0103. Apa ar fi putut p\u0103trunde ulterior \u00een aceste fisuri, cresc\u00e2nd presiunea \u00een interiorul rocilor \u0219i f\u0103c\u00e2nd faliile mai u\u0219or de deplasat. Studiul citat nu stabile\u0219te c\u0103 apa subteran\u0103 a provocat cutremurele.<\/p>\n

\u00cenca nu exist\u0103 dovezi clare despre efectuarea testelor nucleare<\/h2>\n

Fenomenul complic\u0103 monitorizarea viitoare a siturilor unde au avut loc teste nucleare. Cutremurele produse de explozii pot fi mai greu de diferen\u021biat de activitatea tectonic\u0103 natural\u0103 atunci c\u00e2nd efectele persist\u0103 ani de zile.<\/p>\n

Cercet\u0103torii nu au g\u0103sit dovezi c\u0103 Phenianul<\/a> ar fi efectuat teste nucleare dup\u0103 2017. Echipa nu a avut acces la poligonul Punggye-ri sau la datele seismice colectate de Coreea de Nord.<\/p>\n

\u00cen acela\u0219i timp, surse interna\u021bionale au raportat c\u0103 infrastructura sitului nuclear a fost reparat\u0103. Agen\u021bia Interna\u021bional\u0103 pentru Energie Atomic\u0103 a observat activit\u0103\u021bi de restaurare a tunelurilor \u00eencep\u00e2nd din 2022, iar o evaluare american\u0103 din 2025 a indicat c\u0103 poligonul a fost ref\u0103cut.<\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"
