I-volcano kuphela esebenzayo eNorway itholakala ekupheleni kweNyakatho-mpumalanga yesiqhingi saseJan Mayen, ephakathi kweNorway neGreenland Sea. Ibizwa ngokuthi i-Berenberg, ehumusha njenge-Bear Mountain. Intaba-mlilo yaseBerenberg yiyona enyakatho kunazo zonke izintaba-mlilo ezisebenzayo emhlabeni.
Ukuphazamiseka
I-Stratovulkan, ephakeme ngamamitha angu-2277, ibhekwa njengokuphela isikhathi eside; kwavela, ngokusho kososayensi, eminyakeni engaba ngu-700 000 edlule. Uma ngempela "ephaphama", aziwa, kodwa-ke, kukhona idatha yomlando ekukhuphukeni kwe-1732, 1815 no-1851. Ngemva kwalokho, waphinde waphatha ikhefu elifushane, kwathi ngo-September 20, 1970, ukuqhuma kwakhe kwaqala, okwaqhubeka kwaze kwaba nguJanuwari 1971. Ngenxa yalokho, ama-whalers ahlala esiqhingini kwakudingeka asuswe. Ngenxa ye-lava egeleza emfuleni lapho kuqhuma ukuqhuma, indawo yalesi siqhingi yaba sikhulu ngamakhilomitha angama-4. km.
Ngemva kwalokho, uBerenberg "wavuka" ngo-1973. Okunye ukuqhuma - kuze kube manje, owokugcina - kwenzeka ngo-1985 futhi kwagcina amahora angama-40. Phakathi nalesi sikhathi, wathululela cishe amamitha ayizigidi ezingu-7 ububanzi be-lava.
Ama-glaciers
Kuze kube ukuphakama kwamamitha angu-500 emithambekeni yezintaba zimbozwe ngeqhwa. I-volcano crater, enezinga elilinganiselwa ku-1 km, londla ama-glaciers endaweni engama-khilomitha angu-117 square. km. Ezinhlanu zazo zifinyelela olwandle. Okude kunazo zonke yi-Weyprech; ivela engxenyeni ebhujisiwe yomngcele we-crater enyakatho-ntshonalanga ye-glacier.
Ucwaningo lwesayensi
Ngokokuqala ngqa, ukukhuphuka komlilo wenyuka eBerenberg kwenziwa ngamalungu ohambo lwesayensi ngo-Agasti 1921. Lolu hambo lwalubandakanya abantu ababili baseNgilandi - uJames Mann Uordi, umhloli wama-polar kanye ne-geologist, nomsunguli wemvelo uCharles Thomas Lethbridge, kanye nomqondisi wezemvelo waseSwitzerland uPaul Louis Merkanton.
Ngemuva kokuhambela kokuqala emithambekeni ye-volcano, isiteshi sezulu sasungulwa. Isebenza lapha namhlanje; itholwa ososayensi abavela eNorway Meteorological Institute.
Ungafika kanjani ku-volcano?
Kunzima kakhulu ukufika esiqhingini saseJan Mayen: ngaphezu kweqiniso lokuthi ayikho isikhumulo sezindiza noma ichweba, lesi siqhingi singatholakala kuphela ngemva kokuthola imvume yommeleli waseNorway. Cishe nje ithuba lokubonga intaba-mlilo yaseBerenberg ukuthola ukuvakasha kwelinye lezinkampani zokuvakasha zaseNorway. Kungcono ukuvakashela lesi siqhingi ngo-May-Juni
