Ukufunyanwa kwakutshanje kwe Iinyikima ezincinci ze-131 phantsi kweLas CaƱadas del Teide Oku kuphinde kwabeka iTenerife kwindawo ephambili kumajelo eendaba. Lo mfanekiso ungabonakala uthusa xa uwujonga ekuqaleni, kodwa idatha yobugcisa kunye nohlalutyo lwesayensi lubonisa ukuba uzolile kunokuba ube nexhala.
Ngokweengxelo ezivela kwiNational Geographic Institute (IGN), yi- umsebenzi wenyikima obuthathaka kakhuluLo msebenzi wenziwe ngohlobo oluxutyiweyo kwaye uphindaphindwa rhoqo, uhambelana nokuziphatha okuqhelekileyo kwesiqithi sentaba-mlilo esijongiweyo. Okwangoku akukho zimpawu zibonisa ukuqhuma okuzayo okanye ukwanda okukhulu komngcipheko wentaba-mlilo.
Yintoni eyaziwayo ngeenyikima ezili-131 ezibhalwe phantsi kweNtaba iTeide
I-IGN iqinisekisile ukuba, ukusukela ngobusuku Ngomhla wesi-3 ku-Epreli, ukuqala ngentsimbi ye-22:47 ebusuku., a uthotho lweziganeko zenyikima phantsi kweTeide National Park. Xa zizonke, zibaliwe Iinyikima ezili-131 zendalo exutyiweyo kwindawo yaseLas CaƱadas kwiintsuku ezimbalwa ezidlulileyo.
Ezi nyikima zenzeka ngendlela iipulses zamandla aphantsi kakhulu ezihamba nemiqondiso yefrikhwensi ephantsiEzi ziimpawu zohlobo lomsebenzi wokunyikima onxulunyaniswa neenkqubo zangaphakathi ezinzulu ngaphakathi kwenkqubo yentaba-mlilo. Iingcali zigxininisa ukuba akukho nanye kwezi ziganeko eye yaviwa ngabantu baseTenerife. Olu hlobo ukunyikima okuncinci Ixhaphakile kwizakhiwo ezibekwe esweni zentaba-mlilo.
Kuzo zonke iinyikima ezifunyenweyo, amaqela obuchwephesha e-IGN akwazile fumana ngesandla phakathi kweziganeko ezingama-31 kunye nama-33Ngokweendlela ezahlukeneyo zokucuthwa kwamaxesha ezihlalutyiweyo, le ndawo isetyenziswa ngesandla ivumela ukumiselwa ngokuchanekileyo kobunzulu kunye nendawo yee-hypocenters phantsi kweLas CaƱadas.
Amaxabiso arekhodiweyo aphantsi kakhulu: phakathi kwe-0,4 kunye ne-1,6 mbLgLa manqanaba amandla athathwa njengento eqhelekileyo i-micro-seismicity enobukhulu obuphantsi ezinxulunyaniswa neenkqubo zentaba-mlilo ezisebenzayo kwaye zingaphantsi kakhulu kunomda wokuqonda komntu, yiyo loo nto kungekho ngxelo zokungcangcazela ezifunyenweyo kubemi.
Uninzi lweendawo zoxinzelelo lwegazi zigxile kakhulu ubunzulu obuphakathi kweekhilomitha ezi-5 nezili-18 ngaphantsi komphezulu, uninzi lwazo lumalunga neekhilomitha ezili-10 ubunzulu. Olu bunzulu luhambelana neendawo ezinzulu zesakhiwo sentaba-mlilo, apho ukulungiswa kunye nokuhamba kolwelo kunokwenzeka ngaphandle kokubangela utshintsho olubonakalayo kumphezulu.
Isiqendu senyikima esingenalo iphethini yesaqhwithi
Enye yezinto eziphambili ezisetyenziswa zizazinzulu ukuvavanya ingozi yesiganeko esifana nesi iphethini yexesha kunye namandla eenyikimaKule meko, iingcali ze-IGN zigxininisa ukuba umsebenzi orekhodiweyo Ayilandeli ulwakhiwo oluqhelekileyo lwe-seismic swarm, njengalezo zabonwa kwiinyanga ezidlulileyo.
Endaweni yokwanda okukhawulezileyo nokunzulu kokungcangcazela, oko kubonwayo iipulses ezizodwa zomsebenzi we-seismiczahlulwe ngexesha nangamandla aphantsi kakhulu. Imiqondiso erekhodiweyo ihambelana iziganeko zexesha elide (LP), ixhaphakile kwiindawo ezinentaba-mlilo apho ulwelo lubandakanyeka khona kubunzulu.
Iingcali zithi, ukusukela ngoMatshi ophelileyo, Intshukumo yokunyikima komhlaba kwindawo ejikeleze iNtaba iTeide ayizange iphele ngokupheleleyo.Ngamanye amaxesha, ziye zabonwa iipulses ezincincikodwa rhoqo ngaphakathi koko kuthathwa njengokuziphatha okuqhelekileyo kwisakhiwo sentaba-mlilo esifana neTeide.
Ngaphezu koko, idatha yangoku ibonisa ukuba Umsebenzi orekhodwe kwiintsuku zakutshanje ubuthathaka kunokuba kubonwe kwiziqendu ezidlulileyo. Kangangexesha elimalunga neentsuku ezintathu okanye ezine, ii-micro-earthquakes ezili-131 zithathwa njengenani eliphantsi xa kuthelekiswa nezinye izigaba ezinzima ngakumbi.
Konke oku kukhokelela iingcali ekubeni zigxininise ukuba, nangona lo msebenzi ufanele ukubekwa esweni okuqhubekayo nokucokisekileyoOku akuhambelani neepateni ezandulela ukuqhuma kwentaba-mlilo kwiCanary Islands okanye ezinye iinkqubo ezifanayo. Amava akutshanje kunye nohlalutyo olupapashweyo lwee-seismic spikes kwisiqithi zinceda ekucaciseni ezi ziganeko ngokwemeko (Uhlalutyo lokuthelekisa).
Ngaba kukho umngcipheko wokuqhuma kwentaba-mlilo eTenerife?
Umbuzo obuzwa rhoqo phakathi kwabemi kunye neendwendwe ucacile: Ngaba ezi nyikima ze-131 zithetha ukuba kukho umngcipheko omkhulu wokuqhuma? Impendulo evela kwiNational Geographic Institute ayicacanga: ngolwazi olufumanekayo, Akukho nto ibonisa ukuba kuza kuqhuma uqhushumbo oluzayo. okanye ukwanda okukhulu kwengozi kwixesha elifutshane okanye eliphakathi.
Abo baphethe ugcino-zincwadi babonisa ukuba Akukho zimpawu zokuqala zakudala ezifunyenweyo ukuphinda kuqhume uqhushumbo, njengokwanda okuphawulekayo nokuqhubekayo kobukhulu beenyikima, ukungcangcazela okuvakala ngokucacileyo ngabantu, ukuguquka okukhawulezileyo komhlaba okanye utshintsho olukhawulezileyo kwi-geochemistry yeegesi zentaba-mlilo.
Njengoko kuchaziwe ngabaphathi be-IGN, Amathuba okuba kubekho uqhushumbo awakatshintshi xa kuthelekiswa neeveki ezidlulileyo. Olu ngcelele lweenyikima luhambelana notshintsho lwangaphakathi kunye nokujikeleza kolwelo kubunzulu, ngaphandle kokutshintshwa ngqo kumphezulu ngendlela yokuqhekeka okukhulu okanye ukukhuphuka ngokukhawuleza kwe-magma.
Ukuze amanye amanqanaba esilumkiso asebenze, izazinzulu kuya kufuneka ziqwalasele indibaniselwano yezinto: iinyikima ezinkulu kakhulu kwaye zavakala ngokucacileyoUtshintsho olufana nolwe-sulfur dioxide oluvela ngaxeshanye luyenzeka phantsi komhlaba kunye notshintsho olukhulu ekukhutshweni kweegesi ezifana ne-sulfur dioxide. Akukho nanye kwezo zinto ebonakalayo phantsi kweNtaba iTeide okwangoku.
Ngenxa yoko, imibutho esemthethweni igxininisa umyalezo oneentsingiselo ezimbini: Ukubeka iliso elibukhali kakhulu kunye nesayensi, kodwa ngaphandle koloyikoUmsebenzi okhoyo ngoku ukwimeko eqhelekileyo yesiqithi esinentaba-mlilo, kwaye naluphi na utshintsho olufanelekileyo luya kwaziswa ngoko nangoko kwabasemagunyeni nakubemi.
Enye yezona nethiwekhi zokujonga iintaba-mlilo ziphambili
Enye yezona zinto ziqinisekisayo kukubakho kwiZiqithi zaseCanary inethiwekhi yokujonga intaba-mlilo exineneyo kakhulu neyanamhlanjeETenerife kuphela, i-IGN ithumele izikhululo zokujonga i-seismological, geodetic, kunye ne-geochemical ezingaphezu kwekhulu ezisasazwe kulo lonke isiqithi. inethiwekhi yokujonga intaba-mlilo kwaye iimaphu ezisebenzisanayo zinceda ekucaciseni imeko yezixhobo.
Olu lwakhiwo luvumela esweni ngexesha lenene Iiparameter eziphambili ezifana ne-seismicity (kuquka i-microseismicity), ukuguqulwa komhlaba okulinganiswe ngeendlela ze-geodetic, kunye nokwakheka kweegesi ezikhutshwa yinkqubo yentaba-mlilo kuyahlalutywa. Ukudibana kwazo zonke ezi datha kunika umfanekiso ochanekileyo kakhulu wemeko yangaphakathi yeNtaba iTeide.
Ngenxa yale nethiwekhi, naluphi na utshintsho olubalulekileyo uxinzelelo lwangaphakathi lwenkqubo yentaba-mlilo, intshukumo ye-magma, okanye ukujikeleza kolwelo Iza kubonwa kwangethuba. Ezi zikhululo zenzelwe ukubamba nemiqondiso ye-amplitude ephantsi kakhulu, emva koko zihlalutywa ngokweenkcukacha kwiilebhu ze-IGN.
Isiqithi saseTenerife, okwangoku, sikhona enye yezona ndawo zibalaseleyo zentaba-mlilo eYurophuOku kuvumela izigqibo ezisekelwe kulwazi oluqhubekayo noluqinisekisiweyo. Olu lwazi lokuhlala ujonge izinto yilo oluxhasa umyalezo wokulumkisa kodwa ukuqinisekiswa okunikezelwa zizazinzulu.
Ngaphezu koko, ulwazi oluveliswa zezi zikhululo lukwabelwana ngalo rhoqo neminye imibutho yenzululwazi kunye neyokhuseleko loluntu, iindlela zokuqinisa impendulo xa kukho naluphi na utshintsho kwinqanaba lomngcipheko.
Idatha yexeshana kunye nohlengahlengiso olunokwenzeka kubalo
Nangona inani le Iinyikima ezili-131 kwindawo yaseTeide Ipapashwe esidlangalaleni njengesalathiso; i-IGN ngokwayo icacisile ukuba idatha yexeshanaIsizathu silula: uhlalutyo lwee-microseisms ezisebenzisa i-low-frequency yinkqubo enzima efuna ixesha kunye nokuhluzwa ngononophelo olukhulu.
Enyanisweni, iingcali zihlola iirekhodi ezivela kwizikhululo ezahlukeneyo, zisebenzisa iintlobo ezahlukeneyo zokucoca, kwaye Ukufunyanwa ngokuzenzekelayo kulungiswa ngokuhlolwa ngesandlaLo msebenzi mhle ungatyhila ezinye iziganeko eziphantsi kakhulu ezingazange zibonwe ekuqaleni kubalo lokuqala.
Ngenxa yeso sizathu, akunakuphikiswa ukuba inani leenyikima ezifunyenweyo liyanda kancinci njengoko uhlalutyo luqhubeka. Kunokuba yingxaki, olu hlaziyo lunokwenzeka lukwinqanaba eliqhelekileyo lokulawula idatha ye-seismic enobuzaza kakhulu.
Iingcali ziyayikhumbula loo nto olu hlobo lwe-hybrid kunye ne-seismicity yexesha elide Ixhaphake kakhulu kwiinkqubo zentaba-mlilo ezisebenzayo kwihlabathi liphela. Idla ngokunxulunyaniswa nokuhamba kolwelo (amanzi, iigesi, okanye i-magma) kubunzulu obukhulu, ngaphandle kokuthetha ukuba le nkqubo iya kubangela ukuqhuma komphezulu.
Nokuba kunjalo, i-IGN izibophelele ekuqhubekeni ingxelo ngokukhawuleza naziphi na iinguqu ezifanelekileyo ekuphuhlisweni kochungechunge lwe-seismic nasekutolikweni kwedatha, kugcinwa ukuhamba rhoqo konxibelelwano nabasemagunyeni basekuhlaleni nabengingqi.
Imeko eqhelekileyo yentaba-mlilo kunye nokubekwa esweni okuqinisiweyo
Imeko yangoku eTenerife iphantsi koko iingcali zikubiza ngokuba "ubomi obuqhelekileyo kwimisebenzi yentaba-mlilo"Esi siqithi, ngokwendalo yaso, siyindawo apho ukunyikima okuphantsi kobukhulu behlabathi kuyinxalenye yokusebenza okuqhelekileyo komhlaba ongaphantsi komhlaba.
Okutshintshileyo ngokuhamba kwexesha kukuba ubuchule beteknoloji bokubona nokuba kunyikima okuncinciNamhlanje, kuqoshwa imiqondiso ebingenakubonwa kwaphela kwiminyaka embalwa eyadlulayo. Olu phuculo kwizixhobo lunokunika umbono wokuba kukho umsebenzi omninzi, ngelixa eneneni oko sinako kukujongwa okuchanekileyo ngakumbi.
Iingcali zesayensi zigxininisa ukuba Iinyikima ezili-131 ezirekhodiweyo kule mihla zimbalwa ixesha leentsuku ezintathu okanye ezine xa kuthelekiswa nezinye iziganeko zentaba-mlilo ezisebenza ngakumbi, zombini kwiZiqithi zaseCanary nakwezinye iindawo zehlabathi.
Okwangoku, ingcebiso ngokubanzi kubemi kunye neendwendwe icacile: Landela ulwazi olusemthethweni kwaye uphephe ukutolikwa okuxhalabisayo ezinokujikeleza ngaphandle kokuxhaswa yinzululwazi. INtaba iTeide iseluphawu lwendalo nolukhenketho lwesiqithi, kwaye imisebenzi yangoku ayitshintshi iimeko zokhuseleko kwiPaki yeSizwe.
Ngedatha ekhoyo, iingcaciso ezinikezelwa yi-IGN kunye nokuqina kwenethiwekhi yokujonga iintaba-mlilo kwiZiqithi zaseCanary, uthotho lwe Iinyikima ezili-131 kwiNtaba iTeide zitolikwa njengesiganeko sokuzamazama komhlaba okuncinci Oku kuqhelekile kwinkqubo yentaba-mlilo esebenzayo kodwa ezinzileyo. Ukubeka esweni kuya kuqhubeka ngokusondeleyo, kodwa imeko isahlala iqhelekile kubomi bemihla ngemihla eTenerife.
