Galingas 2025 m. \u017eem\u0117s dreb\u0117jimas prie Rusijos Kam\u010diatkos pusiasalio krant\u0173 suk\u0117l\u0117 cunam\u012f, kur\u012f pirmiausia pamat\u0117 ne pakrant\u0117s steb\u0117tojai, o kosminiai palydovai.
NASA pavir\u0161ini\u0173 vanden\u0173 ir vandenyn\u0173 topografijos (SWOT) misija u\u017efiksavo net 120 kilometr\u0173 plo\u010dio bang\u0105 \u2013 vien\u0105 \u012fsp\u016bdingiausi\u0173 kada nors matyt\u0173 i\u0161 kosmoso.<\/p>\n
Nors did\u017eiuli\u0173 bang\u0173 pakrant\u0117se neu\u017efiksuota, Ramiojo vandenyno pavir\u0161ius tiesiogine to \u017eod\u017eio prasme \u201epakyla ir nusileid\u017eia\u201c \u2014 ir b\u016btent tai leido mokslininkams geriau suprasti, kas i\u0161 tikr\u0173j\u0173 vyko j\u016bros dugne.<\/p>\n
8,8 balo sm\u016bgis ir 400 km ply\u0161imo zona<\/p>\n
\u017dem\u0117s dreb\u0117jimo galia siek\u0117 8,8 balo. Sm\u016bgiai sutrikd\u0117 mil\u017eini\u0161k\u0105 Ramiojo vandenyno plot\u0105 ir suk\u0117l\u0117 cunamio bangas, kurios plito dideliu atstumu. Naudodami SWOT ir gilumini\u0173 cunami\u0173 pl\u016bdur\u0173 (NOAA DART sistemos) duomenis, tyr\u0117jai sudar\u0117 \u017eem\u0117lap\u012f, kaip ply\u0161o tektonin\u0117s plok\u0161t\u0117s. Paai\u0161k\u0117jo, kad ply\u0161imas driek\u0117si ma\u017edaug 402 kilometrus, o kai kurios j\u016bros dugno dalys pakilo net iki 4 metr\u0173.<\/p>\n

Kaip palydovai \u201emat\u0117\u201c cunam\u012f<\/p>\n
DART sistema matuoja sl\u0117gio poky\u010dius j\u016bros dugne ir siun\u010dia informacij\u0105 \u012f pavir\u0161inius pl\u016bdurus bei palydovus. SWOT palydovas \u0161iuos duomenis papild\u0117 detaliu vandenyno pavir\u0161iaus auk\u0161\u010dio vaizdu. Tyr\u0117jams pavyko tiksliai u\u017efiksuoti cunamio form\u0105, jud\u0117jim\u0105 ir greit\u012f \u2014 beveik realiuoju laiku. Tai unikalus atvejis: dar niekada \u0161ios misijos palydovas nebuvo fiksav\u0119s tokio stipraus \u017eem\u0117s dreb\u0117jimo padarini\u0173.<\/p>\n
Ry\u0161ys su 1952 m. katastrofa<\/p>\n
Analizuodami duomenis, mokslininkai pasteb\u0117jo ir istorini\u0173 paraleli\u0173.
Palyginus cunamio signalus su informacija apie 1952 m. t\u0105 pat\u012f region\u0105 sukr\u0117tus\u012f ma\u017edaug 9 bal\u0173 \u017eem\u0117s dreb\u0117jim\u0105, paai\u0161k\u0117jo, kad senoji nelaim\u0117 nei\u0161laisvino visos \u012ftampos l\u016b\u017eio zonoje.<\/p>\n
Tai gal\u0117jo tapti viena prie\u017eas\u010di\u0173, kod\u0117l \u012fvyko naujas galingas dreb\u0117jimas 2025-aisiais. Paradoksalu, bet 1952 m. dreb\u0117jimas buvo labiau pra\u017e\u016btingas, nors technologijos tuomet nesuteik\u0117 tokios ankstyvo persp\u0117jimo galimyb\u0117s kaip \u0161iandien.<\/p>\n
K\u0105 \u0161is atradimas kei\u010dia<\/p>\n
\u0160i analiz\u0117 suabejojo da\u017enai kartojama teorija, kad tokio masto dreb\u0117jimai konkre\u010diuose regionuose vyksta kart\u0105 per kelis \u0161imtus met\u0173.<\/p>\n
Palydov\u0173 ir jutikli\u0173 derinys rodo: \u012ftampos kaupimosi procesai gali b\u016bti sud\u0117tingesni ir nenusp\u0117jami. Tai svarbi \u017einia cunami\u0173 persp\u0117jimo sistemoms \u2014 kuo tiksliau suprantamas j\u016bros dugno jud\u0117jimas, tuo grei\u010diau galima \u012fvertinti rizik\u0105 pakrant\u0117ms.<\/p>\n
\u017dvilgsnis \u012f vandenyn\u0105, kuris gelbsti gyvybes<\/p>\n
SWOT misija buvo paleista 2022 m., o \u0161is \u012fvykis tapo vienu reik\u0161mingiausi\u0173 jos rezultat\u0173. Palydovai ne tik \u201efotografuoja\u201c bangas \u2014 jie padeda kurti modelius, galin\u010dius i\u0161gelb\u0117ti gyvybes ateityje.<\/p>\n
Cunamiai ne visada pasirei\u0161kia drasti\u0161komis bangomis pakrant\u0117se. Kartais tik kosmosas leid\u017eia pamatyti j\u0173 tikr\u0105j\u012f mast\u0105 \u2014 ir tai \u0161\u012fkart pad\u0117jo mokslui \u017eengti dar vien\u0105 \u017eingsn\u012f \u012f priek\u012f.<\/p>\n
