Ukuwa kweGlacial kwakhokelela kwiSiganeko seNyikima eNepal 

Isiganeko sokunyikima komhlaba esinobukhulu obuyi-5.2 esibhalwe kufutshane nomda ophakathi kweNepal neTshayina ngomhla wama-26 kweyeThupha ngo-2026 ngentsimbi ye-8:37 AM ngexesha lendawo (02:52:10 UTC) ngoku sifunyenwe njengengozi yokuwa komkhenkce kunye nokuhamba kobumdaka okubangele iimpembelelo ezimbi kakhulu ngezantsi komlambo. 

Esi siganeko sokunyikima komhlaba saqala saxelwa njengenyikima enobukhulu obuyi-4.4. Nangona kunjalo, uhlalutyo olongezelelekileyo lwamaza okunyikima komhlaba athathe ixesha elide kunye nemifanekiso yesathelayithi lutyhile ukuba akukho nyikima yenzekileyo kulo mmandla. Amandla okunyikima komhlaba aveliswa kukudilika komkhenkce kunye nokuhamba kobumdaka. 

Isikhukula esiqhambukileyo sibangelwe yiqhwa namatye avela kwiqhwa kwindawo ephezulu yamanzi eyatshayela umlambo iBhote Koshi-Trishuli ngaphesheya komda weNepal-China. Isikhukula esibi kakhulu kunye nokudilika kodaka kubangele umonakalo omkhulu kubomi babantu kunye nempahla kulo mmandla. Kubikwa ukuba abantu abamalunga ne-160 bafile (inani lexeshana) kwaye amakhulu alahlekile. 

Kwixesha elidlulileyo, ukuqhuma kwechibi elinomkhenkce kubangele izikhukula ezinkulu kunye nokudilika kodaka kuMlambo iThame kwisithili saseSolukhumbu eNepal ngomhla we-16 kweyeThupha ngo-2024. 

Isiganeko esiqhelekileyo sokunyikima esingabangelwanga yinyikima saxelwa nge-16 kaSeptemba 2023 eGreenland xa izikhululo zokunyikima kwihlabathi liphela zarekhoda amaza okunyikima aqhelekileyo ahlala iintsuku ezisithoba. Amaza esi siganeko sokunyikima akubonakala ngathi abangelwa yinyikima okanye yintaba-mlilo. Uhlalutyo oluneenkcukacha lutyhile ukuba ukutyibilika okukhulu kwamatye okubangelwe lutshintsho lwemozulu kudale i-tsunami enkulu kwiDickson Fjord ekude empuma yeGreenland. Ukunyikima okubangelwe kukutyibilika kwetsunami ngaphesheya kwefjord kurekhodwe kwihlabathi liphela njengamaza okunyikima ahlala ixesha elide. 

Ngokuqhelekileyo, iziganeko ze-seismic ezenzeka ngokwendalo zibangelwa ziinyikima ngenxa yokuhamba kweeplate ze-tectonic, nangona kunjalo iziganeko ze-seismic ngamanye amaxesha zibangelwa ziziganeko zendalo ezigqithisileyo ezifana nokuwa komkhenkce kunye ne-volcano kunye neziganeko ze-anthropogenic ezifana novavanyo lwenyukliya olungaphantsi komhlaba.
