Iziphathimandla zaseCaribbean zixwayise intaba-mlilo i-Kick 'Em Jenny (KeJ) ngaphansi kwamanzi ingase iqhume emahoreni angu-24 alandelayo. Indawo engabalelwa ku-5km ibekwe uhulumeni waseGrenada.
“Siqapha isimo, esilethwe yiSeismic Research Center (SRC) yaseNyuvesi yaseWest Indies eTrinidad,” kusho uMqondisi woMnyango Wezokuphathwa Kwezimo Eziphuthumayo (DEM) uKerry Hinds njengoba ekhonjwe nguSt. Lucia Times.
Izinga lesexwayiso linyusiwe lisuka kokuphuzi laya kokuwolintshi ngoLwesithathu, okubonisa, “izinga eliphezulu kakhulu lomsebenzi wokuzamazama komhlaba kanye/noma we-fumarolic noma omunye umsebenzi ongajwayelekile. Ukuqhuma kungase kuqale ngesaziso esingaphansi kwamahora angamashumi amabili nane.” I-KeJ itholakala eduze komzila obalulekile wokuthutha phakathi kwe-St Vincent ne-Grenada.
Izazi ze-Seismologists zikholelwa ukuthi ayikho ingozi esheshayo esifundeni, kuhlanganise nama-tsunami. USolwazi Richard Robertson, weWest Indies Seismic Research Centre (SRC) uthe, uma kwenzeka kuqhuma, i-KeJ ngeke ikhiphe izinto ezanele ukuze isuse amanzi anele ukuze kube ne-tsunami, kodwa ukukhishwa kwegesi kunganciphisa ukushuba kwemikhumbi eseduze. .
I-KeJ iqhume okungenani izikhathi eziyishumi nambili kusukela yatholwa ngo-1939 lapho ifu lomlotha elingamamitha angu-270 ukuphakama (886ft) libonakala likhuphuka olwandle. Ngokusekelwe ekuhlaziyweni kwamashumi eminyaka ocwaningo, intaba-mlilo ibonakala iqhuma cishe njalo ngemva kweminyaka eyi-10, kodwa ayizange ibangele ukufa okurekhodiwe.
Amandla kazibuthe kagesi akhishwa amasathelayithi ukuze ahlole izintaba-mlilo ezisekelwe emhlabeni awakwazi ukungena emanzini, ngaphandle kwamanzi, noma 'umkhumbi-ngwenya', izintaba-mlilo ezivela ezinhlelweni zocwaningo ezisekelwe emkhathini zesikhathi eside. Umphakathi wesayensi wazi kancane ngokuqhathaniswa nezintaba-mlilo zangaphansi kolwandle ngenxa yalokho.
Ngonyaka odlule, uKick-'em-Jenny, okucatshangwa ukuthi uqanjwe ngamanzi anomsindo awuzungezile, waqala ukuqhuma njengeqembu lase-Imperial College London, Southampton kanye namanyuvesi e-Liverpool, ngokubambisana ne-University of the West Indies Seismic Research Centre ( SRC), bebeqoqa ama-seismometer asuka phansi olwandle. Ithimba likwazile ukuqopha imiphumela esheshayo yokuqhuma kwamanzi, ukubhekwa okuqondile okuyivelakancane kakhulu.
“Kunenhlolovo yendawo yaseKick-'em-Jenny ehlehlela emuva eminyakeni engu-30, kodwa inhlolovo yethu ngo-April 2017 ihlukile ngoba yalandela ukuqhuma ngokushesha. Lokhu kusinike imininingwane engakaze ibonwe mayelana nokuthi lo msebenzi wentaba-mlilo ubukeka kanjani, kunokuthembela ekuchazeni izimpawu zokuzamazama komhlaba,” kusho umbhali oholayo umfundi we-PhD uRobert Allen, ovela eMnyangweni wezeSayensi Nobunjiniyela e-Imperial, esitatimendeni sabezindaba.
