Ukutsheka kwe-eksisi Yomhlaba kanye nenani lamahora okukhanya emini liyashintsha

Ukutsheka kwe-eksisi Yomhlaba kanye nenani lamahora okukhanya emini liyashintsha

Ngemva kokuhlaziya ukunyakaza kwamagagasi e-seismic kanye nezinguquko zakamuva, iqembu labacwaningi baseShayina liqinisekisile ukuthi ingaphakathi loMhlaba lishintshe i-axis yawo yokuzungeza.

Abacwaningi baveze ukuthi ukushintsha ukuzungeza komnyombo ongaphakathi woMhlaba kuzonciphisa ubude bezinsuku ngengxenye yesekhondi unyaka wonke, ocwaningweni olushicilelwe kumagazini wesayensi i-Nature Geoscience, ngoMsombuluko.

Baphinde baveza ukuthi lokhu kuzophinde kube nomthelela omncane emkhakheni kazibuthe woMhlaba, ngokusho kwabikwa yi-Wall Street Journal.

Ukuzamazama komhlaba kanye nokuzamazama komhlaba

Ngokulandelayo, umsizi womcwaningi ocwaningweni nochwepheshe we-seismology wase-University of Peking, i-Xiadong Song, uthe ngokombono, lolu daba lwathatha isikhathi eside, kodwa kunezinkomba zokuthi lwaqala emashumini eminyaka edlule.

U-Song waphawula ukuthi ukuzungezisa kwengqikithi yoMhlaba engaphakathi kubangelwa amandla kazibuthe akhiqizwa ungqimba oluwuketshezi olungaphandle, futhi ukufunda ukunyakaza kwawo kungasiza ososayensi baqonde ukuthi izingqimba ezihlukene zomhlaba zixhumana kanjani.

Uphinde wafunda ngamagagasi okuzamazama komhlaba abangelwa ukuzamazama komhlaba futhi wawaqhathanisa nokuzamazama okufanayo ngeminyaka yamashumi ayisithupha, wathola ukuthi ukuzungeza kwenkaba yoMhlaba engaphakathi kuma phakathi kuka-2009 no-2020, futhi baphakamisa ukuthi kubuyisele emuva indlela yokuzungeza kwawo, ethi: "Sinalokhu kuzamazama komhlaba okwenzeka ezindaweni ezifanayo ... sasibeka Umhlaba kulokho okubukeka njenge-tomogram."

umbono wesibili

Kodwa-ke, uprofesa wase-University of Southern California, uJohn Vidal, ongazange ahlanganyele ocwaningweni olusha, unomunye umbono, njengoba ethole ukuthi kungase kube nokunye ukuhlaziya idatha enikezwe abacwaningi, nokuthi izinguquko abacwaningi abaqaphelile bathembekile, kodwa isizathu esiqondile salokho okwenzeka empeleni asicacile.

Ugcizelele ukuthi ukuhlaziya kwabacwaningi kuhle kakhulu futhi inkolelo-mbono yabo eshiwo ocwaningweni muhle uma uyiqhathanisa naleyo ekhona njengamanje, kodwa kuneminye imibono engaqhudelana nayo, esho.

UVidal uthe abanye ososayensi bakholelwa ukuthi izinguquko ekujikelezeni komgogodla woMhlaba zifushane kuneminyaka engamashumi ayisikhombisa ucwaningo olugxile kuyo, kuyilapho imibono eyakhiwe ngabanye ososayensi ikhomba ukuthi ingaphakathi liyekile ukuhamba phakathi kuka-2001 no-2003 noma ukuthi ukujikeleza kwawo. umnyakazo awuzange uhlehliswe. Isitayela sakhe sokunyakaza sashintsha.

Kuyaphawuleka ukuthi umnyombo wangaphakathi woMhlaba uqukethe insimbi ne-nickel, futhi ihlukaniswe nengxenye eqinile yomhlaba ngongqimba lwangaphandle oluwuketshezi, olusiza ukuguqula ukunyakaza kwayo ngokuhlukile kulo lonke iplanethi.

Izexwayiso zalezi zinkanyezi zonyaka ka-2023
