Abahanga mu by’ubumenyi bw’ikirere n’imiterere y’imisozi bavuga ko isenyuka ry’igice kinini cy’urubura rwo ku misozi ya Himalaya rishobora kuba ari ryo ryateje imyuzure n’inkangu byahitanye abantu benshi ku mupaka wa Nepal na Tibet.
Imyuzure ikomeye yibasiye uduce two ku mupaka wa Nepal na Tibet ku wa Gatatu, tariki ya 26 Kanama 2026, yasize imiryango itari mike mu kaga, amazu n’imihanda birangirika ndetse n’abantu benshi barabura.
Ku ikubitiro, amakuru yari yatanzwe yavugaga ko umutingito ushobora kuba ari wo wateje inkangu, nayo igakurikirwa n’imyuzure.
Icyakora, nyuma y’isuzuma ryakozwe n’abahanga, Ikigo cy’Amerika gishinzwe ubushakashatsi ku miterere y’isi (USGS) cyavuze ko icyo gikorwa cyari gifitanye isano n’isenyuka ry’urubura rwo ku misozi n’inkangu y’ibyavuyemo, aho kuba umutingito nyirizina.
Isenyuka ry’urubura ryateje umwuzure ukomeye
Abahanga bavuga ko igice kinini cya glacier kiri hafi y’umusozi wa Langtang Lirung, umwe mu misozi miremire ya Himalaya, cyasenyutse kigana mu kibaya.
Dr Simon Cook, impuguke mu byiga glaciers muri University of Dundee, yatangarije BBC ko itsinda rye ryabonye ibimenyetso by’uko igice cyo hasi cy’iyo glacier cyasenyutse. Langtang Lirung iri hafi kilometero 15 uvuye ahabereye umwuzure.
Uburemere n’imbaraga by’icyo gice cy’urubura n’ibitare byaguye mu kibaya byari bikomeye cyane ku buryo byateje kunyeganyega kw’isi kwanditswe nk’igikorwa gifite ubukana bungana na 5.2 ku gipimo cy’ibikorwa by’imitingito.
Icyakora, ibyo ntibivuze ko habayeho umutingito wa 5.2; no kunyeganyega kwatewe n’isenyuka ry’urubura n’ibitare.
Urwo rubura n’ibitare bimaze kugwa, byageze mu ruzi rwa Lhende Khola, bituma amazi menshi, ibitaka, amabuye n’ibindi bisigazwa bitangira gutembera ku muvuduko mwinshi.
Amazi yaje gukomereza mu ruzi rwa Bhote Koshi, nyuma agana muri Trishuli, atwara ibintu byinshi mu nzira.
Abahanga bavuga ko amazi y’umugezi wa Trishuli yazamutse ku kigero cya metero hafi 9 mu gihe kingana n’iminota 30.
Iyi myuzure yangirije bikomeye mu bice bitandukanye bya Nepal, cyane cyane mu karere ka Rasuwa. Amazu, imihanda, ibiraro n’ibikorwa remezo by’amashanyarazi byangiritse cyangwa bitwarwa n’amazi n’ibitaka.
Abantu babarirwa mu magana barapfuye, abarenga 1,300 barabura
Kugeza ku makuru yatangajwe ku wa 27 Kanama, imibare y’abahitanywe n’iyi myuzure yari ikiri kuzamuka.
Muri Nepal, polisi yari yatangaje ko imibiri 177 yari imaze kuboneka, mu gihe abantu 823 bari bakibura. Muri abo babuze harimo abanyamahanga benshi, cyane cyane ba mukerarugendo.
Muri Tibet na ho hari hatangajwe abantu batatu bapfuye n’abandi 558 babura, bituma umubare w’ababuriwe irengero muri Nepal na Tibet urenga 1,300.
Kubera ko hari uduce tutaragerwamo n’abatabazi kubera ko imihanda n’ibiraro byangiritse, hari impungenge ko umubare w’abapfuye ushobora gukomeza kwiyongera.
Abahanga bahangayikishijwe no gushonga kwa glaciers
Iyi mpanuka yongeye kuzamura impungenge ku ngaruka z’imihindagurikire y’ikirere ku misozi ya Himalaya.
Abahanga bavuga ko ubushyuhe bwiyongera butuma glaciers zishonga kandi bigahindura imiterere y’ibitare n’ubutaka byo ku misozi, bikongera ibyago byo gusenyuka kw’urubura, inkangu n’imyuzure itunguranye.
Reuters yatangaje ko Nepal yatakaje hafi kimwe cya gatatu cy’urubura rwo ku misozi mu myaka mirongo itatu ishize, kandi ko umuvuduko wo gushonga ukomeje kwiyongera.
Icyakora, abahanga baracyirinda kuvuga ko imihindagurikire y’ikirere ari yo yonyine yateje iyi mpanuka. Bavuga ko hashobora kuba haragize uruhare ibintu byinshi birimo imiterere y’imisozi, uko urubura ruhagaze ndetse n’ihindagurika ry’ubushyuhe.
Abatabazi bo muri Nepal n’abaturuka mu bindi bice bakomeje ibikorwa byo gushakisha abantu baburiwe irengero no gutabara abagezweho n’iyi mpanuka.
Ariko ibikorwa byo gutabara biragorana kubera ko imihanda n’ibiraro byinshi byangiritse, bigatuma indege za kajugujugu ziba imwe mu nzira z’ingenzi zo kugera mu bice byibasiwe n’ibiza.
Iyi mpanuka ikomeje gufatwa nk’imwe mu mpanuka zikomeye cyane zibaye mu karere ka Himalaya muri iyi myaka, ndetse abahanga bakomeje gukurikirana uko isenyuka ry’urubura n’ihindagurika ry’ikirere bishobora kongera ibyago by’ibiza nk’ibi mu gihe kiri imbere.
