I-National Geographic Institute irekhode oku kwiiyure ezimbalwa ezidlulileyo uthotho oluncinci lweenyikima kwisiqithi sase-El Hierro, zonke ziphantsi kodwa zixinene kwixesha elifutshane kwaye zingaphantsi kolwandle olujikeleze isiqithi.
Ngokwedatha yexeshana evela kwi-arhente, enokujongwa kwi Imephu esebenzayo yeentaba-mlilo ezisebenzayo kunye neenyikima zamva nje, umsebenzi wenyikima wenzekile phakathi kobusuku bangoMvulo noLwesibini kusasa, kunye neenyikima ezininzi ezikwintshona, kumzantsi-ntshona nakumzantsi wommandla we-El Hierro, kubunzulu obukhulu kwaye, ngokomgaqo, akukho ziganeko zibalulekileyo ezixeliweyo.
Iinkcukacha zeenyikima ezintathu eziphambili ezifunyenwe ngoLwesibini
Ulwazi olupapashwe yiNational Geographic Institute luquka Iinyikima ezinkulu ezintathu zirekhodwe ngoLwesibini kusasa, zonke zinobukhulu obuphakathi kwe-2,5 kunye ne-2,9 kwisikali se-mbLg kwaye zivela elwandle olujikeleze isiqithi.
Unyikimo olunamandla kolu ngcelele lufikelele kubukhulu obungama- 2,9 mbLgEsi siganeko besikwicandelo lezolwandle kumzantsi-ntshona we-El Hierro kwaye senzeke e 07: iiyure ze-13, kubunzulu obuqikelelweyo be Iikhilomitha ezili-39 phantsi komgangatho wolwandle, olunxulumene ubume bomhlaba.
Kwiiyure ezingaphambili, i-IGN yayisele irekhode esinye isiganeko sokunyikima komhlaba kuloo ndawo. 03:50 kusasa Kufunyenwe inyikima enkulu kakhulu 2,6, ekwaselwandle, ngeli xesha ikumzantsi womasipala wase-El Pinar, kwaye ine-hypocenter ekufutshane Iikhilomitha ezili-19 nzulu.
Ulandelelwano lwakusasa lugqitywe ngenyikima yesithathu, ka 2,5 mbLg, ibhaliswe e 08: iiyure ze-08Kule meko, indawo yayikwintshona yesiqithi sase-El Hierro, nakwindalo esingqongileyo yolwandle, kubunzulu obukufutshane nesiqithi sase-El Hierro. Iikhilomitha ezili-32 phantsi komphezulu wolwandle.
Ukungcangcazela kwangaphambili ngoMvulo ebusuku
Idatha ibonisa ukuba oku Umsebenzi we-seismic awuzange uqale ngoLwesibinikodwa kwiiyure ezimbalwa ngaphambili. NgoMvulo ebusuku, iNational Geographic Institute ifumanise inyikima yangaphambili enokuthathwa njengesiqalo solu landelelwano.
Loo nyikima yokuqala yarekhodwa kwi 20: iiyure ze-35 NgoMvulo, nakwinxalenye esentshona yesiqithi, kubekho inyikima encinci. 1,7, kwaye yayikwintshona ye-El Hierro, malunga Iikhilomitha ezili-14 ubunzuluNgoko ke, yayiyinto encinci.
Olu hlobo lokungcangcazela, olunefuthe eliphantsi kwaye lufumaneka kwiikhilomitha ezimbalwa ngaphantsi komphezulu, Uqweqwe lomhlaba, Zihlala zingabonwa ngabantuNangona iyinxalenye yemisebenzi yendalo yale ndawo, amaxabiso arekhodiweyo ahlala engaphantsi komda apho uninzi lwabantu luqala khona ukuziva inyikima.
Ubukhulu, ukuqonda kunye nenqanaba lomngcipheko kuluntu
Ubukhulu phakathi 2,5 kunye ne-2,9 mbLg Ubukhulu beenyikima zangoLwesibini buthathwa njengobuphantsi ngokwezinga le-seismological. Iinyikima ezingaphantsi kobukhulu be-3 aziqhelekanga ukuviwa ngokucacileyo luluntu, ingakumbi xa zivela kubunzulu obukhulu njengalezo zibhalwe kwesi siganeko.
Kule meko, amaxabiso anikwe yi-IGN akhomba ku iziganeko zexesha elifutshane, ezincitshiswe ngamandlaAkukho zimpawu zomonakalo kwiziseko zophuhliso okanye ukuphazamiseka okukhulu kubomi bemihla ngemihla kwesi siqithi. Ukudibana kobukhulu obuphakathi kunye ne-sub-weismic foci kunciphisa kakhulu amathuba okuba iinyikima zibe nemiphumo ebonakalayo kumphezulu.
Kubalulekile ukukhumbula ukuba indlela uluntu olubona ngayo inyikima ayixhomekekanga kuphela kubukhulu bayo, kodwa nakwizinto ezifana... umgama ukuya kwindawo ephambi kwayo, ubunzulu be-hypocenter, imiphetho yeeplate ze-tectonicuhlobo lomhlaba okanye iimpawu zezakhiwo. Kwimeko yeziganeko ezibhalwe e-El Hierro, zonke zibekwe phantsi kwamanzi zinzulu ngama-kilomitha angamashumi amaninzi, nto leyo enceda ekunciphiseni impembelelo yazo.
I-El Hierro, isiqithi esijongiweyo ngenxa yendalo yaso yentaba-mlilo
Ukususela kweso siganeko, iNational Geographic Institute kunye nezinye imibutho ekhethekileyo ziye zaqhubeka ukujonga okuqhubekayo Ngokuphathelele umsebenzi wenyikima kunye nowentaba-mlilo kulo mmandla, olu qwalaselo luquka iinethiwekhi ze-seismographs, imilinganiselo ye-geodetic, kunye nezinye izixhobo ezivumela ukubonwa kotshintsho olungaphantsi komhlaba kunye nokuphendula ngokukhawuleza kuyo nayiphi na inguqu ebalulekileyo.
Ulandelelwano lweenyikima ezincinci ezifunyenwe kwiiyure ezimbalwa ezidlulileyo ke ngoko luyinxalenye imeko yolawulo olusisigxinaOku kuqhelekile kwiziqithi zentaba-mlilo eAtlantiki, njengeeCanary Islands. Ukwenzeka kweentshukumo eziphantsi kobukhulu akuthethi ukuba umngcipheko uya kwanda ngoko nangoko, kodwa kubonelela ngolwazi oluxabisekileyo malunga nokuziphatha kwenkqubo yentaba-mlilo kwixesha eliphakathi nelide.
Kwiimeko ezinjalo, amagunya ezenzululwazi agxininisa ukuba Isitshixo kukuhlala uphaphile kunye nohlalutyo lweendlela ezihamba ngayo izinto ngokuhamba kwexesha, endaweni yokutolikwa okuzimeleyo kokungcangcazela okukodwa okanye ngaphezulu kwamandla aphantsi. Le ndlela ivumela ukuchongwa kweepateni ezingaqhelekanga kwaye, ukuba kuyimfuneko, ukusebenza kwangoko kolwazi kunye neenkqubo zokuthintela uluntu.
Ukuza kuthi ga ngoku, idatha ekhoyo ibonisa ukuba uthotho lweenyikima ezincinci ezirekhodwe e-El Hierro Isabela kwiimeko eziqhelekileyo zesiqithi sentaba-mlilo esiphantsi koxinzelelo lwangaphakathi, kunye neenyikima ezincinci, ezinzulu neziphakathi kwindawo yolwandle, ngaphandle kwemiphumo ebalulekileyo kumphezulu kwaye phantsi kweliso eliqhubekayo leNational Geographic Institute.
