Abasemagunyeni kwiCaribbean balumkise uKick 'Em Jenny (KeJ) wentaba-mlilo engaphantsi kwamanzi inokuqhuma kwiiyure ezingama-24 ezizayo. Indawo yokukhutshelwa ngaphandle ye-5km inyanzelwe ngurhulumente waseGrenada.
"Siyibek 'esweni le meko, ethe yaziswa liZiko loPhando ngeSeismic (i-SRC) yeDyunivesithi yaseWest Indies eTrinidad," utshilo uMlawuli weSebe lezoLawulo oluNgxamisekileyo (i-DEM) uKerry Hinds njengoko kucacisiwe nguSt. Ixesha likaLucia.
Inqanaba lesilumkiso laphakanyiswa ukusuka kumbala otyheli ukuya kuorenji ngoLwesithathu, ebonisa, “inqanaba eliphezulu kakhulu lenyikima kunye / okanye nomsebenzi we-fumarolic okanye enye into engaqhelekanga. Ukuqhawuka kunokuqala ngesaziso esingaphantsi kweeyure ezingamashumi amabini anesine. ” I-KeJ ibekwe ecaleni kwendlela ephambili yokuthumela phakathi kweSt Vincent kunye neGrenada.
I-Seismologists ikholelwa ukuba akukho ngozi ikhoyo kwangoko kulo mmandla, kubandakanya neetsunami. UNjingalwazi Richard Robertson, we West Indies Seismic Research Centre (i-SRC) uthe, xa kunokwenzeka uqhushumbe, uKeJ akazukukhupha izinto ezaneleyo zokuhambisa amanzi aneleyo nge tsunami, kodwa ukukhutshwa kwegesi kungakunciphisa ukwanda kweenqanawa kufutshane. .
I-KeJ iqhume ubuncinci amatyeli ali-1939 okoko yafunyanwa ngo-270 xa ilifu lothuthu elingama-886 ukuphakama (10ft) labonwa liphuma elwandle. Ngokusekwe kuphononongo lwamashumi eminyaka yophando, intaba-mlilo ibonakala ngathi iyaqhuma malunga neminyaka eli-XNUMX, kodwa ayikhange ibangele kufa.
Amandla ombane akhutshwa ziziphuphutheki zokufunda iintaba-mlilo ezisekwe kumhlaba awunakungena kumphezulu wolwandle, kuthintela amanzi, okanye 'inkwili' evela kwiinkqubo zophando ezisekwe kwisithuba sexesha elide. Uluntu lwezenzululwazi alwazi kangako malunga neentaba-mlilo ezingaphantsi kolwandle ngenxa yoko.
Kunyaka ophelileyo, uKick-'em-Jenny, ekucingelwa ukuba uza kubizwa ngegama lamanzi angqonge le ndawo, waqalisa ukudubula njengeqela elivela kwiiyunivesithi zase-Imperial London, Southampton naseLiverpool, ngokusebenzisana neYunivesithi yaseWest Indies Seismic Research Centre ( I-SRC), bebeqokelela i-seismometers esemazantsi olwandle. Iqela likwazile ukurekhoda okwenzekileyo kwangoko emva kogqabhuko lwangaphantsi kwamanzi, ukuqatshelwa ngokuthe ngqo kunqabile kakhulu.
“Kukho uphando ngommandla weKick-'em-Jenny obuyela emva kwiminyaka engama-30, kodwa uphando lwethu ngo-Epreli 2017 lukhethekile kuba lwalandela nje uqhushumbo. Oku kusinike idatha engazange ibonwe ngaphambili ukuba ubukeka kanjani kanye lo msebenzi wentaba-mlilo, endaweni yokuthembela ekutolikeni imiqondiso yenyikima, ”watsho umbhali okhokelayo ongumfundi we-PhD uRobert Allen, weSebe lezeNzululwazi yezoMhlaba nezoBunjineli e-Imperial, utshilo kumaphephandaba.
