NgoMgqibelo owedlule ngo-Ephreli 16, 2016 i-Ecuador yabhekana nokuzamazama komhlaba okubi kakhulu kusukela ngo-1979. Ngokufa kwabantu abangama-350, ukuzamazama komhlaba okungu-7,8 okushiye izwe kudilikile. Baningi abantu abashiywe bengenamakhaya, nabanye abangeke bakwazi ukubuyela kubo kuze kube isimo sijwayelekile. Lesi yisimo esibuhlungu sendawo yomhlaba lapho kade ikhona Ukuzamazama komhlaba okungu-40 eminyakeni engama-475 edlule.
Umbuzo uwukuthi, kungani?
Kusukela ekuqaleni kwekhulu leminyaka elidlule, e-Ecuador kuye kwaba nokunyakaza okuyishumi nambili kokuzamazama komhlaba ngamandla amakhulu. Isimo sezwe ngesinye sezizathu esenza ukuthi umsebenzi wokuzamazama komhlaba ubaluleke kangaka esizweni sase-Ibero-American. Futhi i-Ecuador, njengamanye amazwe amaningi anjengeChile, iBolivia, iPanama, iCalifornia noma iJapan, kulokho okuthiwa I-Pacific Ring of Fire. Lesi sifunda singamakhilomitha angama-40.000 ubude, futhi kulapho kwenzeka khona ukuzamazama komhlaba okuqine kakhulu nokuqhuma kwentaba-mlilo.
Kangangokuthi kuyaziwa ukuthi Ukuzamazama komhlaba okunamandla amakhulu angama-80 emhlabeni kwenzeka kulezi zizwe, njengoba kugqanyiswe ngumqondisi wendawo yokuzamazama komhlaba eGeophysical Institute of Peru (IGP), uHerando Taveras.
Ama-Plate tectonics ayimbangela yalezi zimo. IPlanethi yoMhlaba, selokhu yazalwa, ibilokhu iguquka njalo ngenxa yokuhamba kwala mapuleti ahambisa amazwekazi. Ngokuphathelene noLwandlekazi iPacific, luhlala phezu kweziningi zazo, ezihlangana futhi zidale ukuxabana phakathi kwazo. Yile ndlela ukungezwani okwakha ngayo okumele kukhishwe.
Endabeni ye-Ecuador, eChile, ePeru naseColombia, ukunyakaza kungenxa yokuthi iPlate yeNazca uhla ngaphansi kweSouth American Plate.
Ukusuka lapha ngithanda ukuthumela ifayili le- ukwanga okuqinile namandla Okwe-Ecuador. Kuningi, isikhuthazo esikhulu.
