Siye iveki amangqina kuqhushumbe lweCumbre Vieja volcano. Kwaye ngelixa iingcali zisebenza ukucacisa umbuzo wokuba luza kuthatha ixesha elingakanani olu qhushumbo, oluqikelelwa phakathi kweentsuku ezingama-20 ukuya kwezingama-84, iziphumo zemo engqongileyo nezoqoqosho sele zivakala.
Ingqwalaselo yolwazi kunye nengcaciso engeyiyo eSpain ithathwa yiCumbre Vieja volcano. Nangona kunjalo, bobabini i-Etna kunxweme olusempuma yeSicily, kunye neVolcán de Fuego eGuatemala nabo benze umsebenzi kule veki. Kukho intetho eninzi malunga neziphumo, Kodwa ingaba zingayintoni ezi?
ELa Palma icolada ilandelele indlela yayo batshabalalisa iindawo ezinabemi kungoko ke kubangele umonakalo omkhulu kuqoqosho, ngakumbi kwiintsapho eziphulukene namakhaya azo. Kwinqanaba lendalo, nangona kunjalo, kubonakala ngathi sijamelene nemeko ethile kwaye ikwindawo yasekuhlaleni. Ngelixa silinde ukuba i-wash iya kufikelela elunxwemeni, iingcali zithi ukuba kunjalo, oku ngekhe kube nefuthe elimangalisayo okanye eliyingozi nakubantu.
Yintoni egqiba ukuba ingaba iya kuba nefuthe kwindalo esingqongileyo nakwimozulu? Ubungakanani bokuqhuma, ukuphakama kwalo kukhutshwe uthuthu kunye nesixa sazo, zezinye zezinto ezichazayo. Namhlanje kusekutsha kakhulu ukuba ungazi ngqo ukuba yeyiphi impembelelo yokuqhushumba okusebenzayo okuya kuba kwinqanaba lobume bendalo. Kodwa ukuba sinokuqonda ngokubanzi indlela abanokuba yiyo.
Iziphumo zendalo esingqongileyo
Iziganeko zendalo ezinje ngokuqhuma kwentaba-mlilo zineziphumo ezibi kwangoko kwimimandla yasezidolophini, kodwa zithini iziphumo zazo zokusingqongileyo zexesha elifutshane nelide? Kuxhomekeke kubungakanani besi sigqabhuko-dubulo, sifumanisa ubukhulu becala okanye kancinci utshintsho kwi-biodiversity, imihlaba okanye umgangatho womoya.
Ukubuyiselwa komhlaba
Ukuhamba kwelava kuthambeka kuyehla ngeCumbre Vieja Natural Park, ukutshintsha ubume bendawo. Amaphecana omhlaba ochumileyo ongcwatyelwe phantsi kwodaka ziya kuba bubuso bamatye abukhali nokusika aqhelekileyo kuqhushumbo lwakutsha nje okanye oluncinci olwaziwa njengee badlands.
Into eqhelekileyo kwimeko apho kufuneka khona umhlaba ukuba uvelise ngokungxamisekileyo, kukususa imihlaba kwezinye iindawo zelizwe. Kwaye umhlaba ochaphazelekayo ngokwawo, kungathatha iminyaka engama-3.000 4.000 ukuya kuma-XNUMX ukuyifumana kwakhona. Kwimeko ka-La Palma, nangona kunjalo, ikamva lale ndawo linokwahluka: ukuyilwa kwendawo ekhuselweyo yokufunda.
Iigesi eziyityhefu nothuthu
La ukukhutshwa ngesiquphe kwe-CO2 (icarbon dioxide), igesi yendlu eluhlaza ingalinyusa iqondo lobushushu bomaleko womoya, nangona kunjalo, isiphumo saso asiqhelekanga sithathwa njengebalulekileyo xa kufikwa kumba wokunyusa ukufudumala kwehlabathi. Ngaba uyazi ukuba isiphumo sokuqhushumba kwentaba-mlilo ukusukela nge-1750 siphindwe kalikhulu kumonakalo owenziwe kwangelo xesha linye, ngenxa yokutsha kwezibaso? Ngapha koko, kubonakala ngathi le ikwiLa Palma ayinkulu ngokwaneleyo ukuba inokuchaphazela imo yezulu kwanakwinqanaba lendawo.
Ukongeza kwi-CO2, ugqabhuko-dubulo lwentaba-mlilo khupha i-SO2 (isalfure dioxide). Equlathwe ngamafu othuthu aphuma emva kogqabhuko-dubulo, le gesi inokupholisa umoya. Kwaye, xa zidityaniswe nokufuma, zenza i-acidification emanzini emvula. Inokwenzeka, kodwa into enje echaphazela i-ecosystem kufuneka ibe nobukho obuphezulu beesulphate kunye nokuqhubeka kwexesha.
Zombini iigesi ezikhutshiweyo kunye nothuli olucolekileyo, kuxhomekeke kumandla ekugxothwe ngawo kunye nobukhulu bokudubula. iqhutywa yimisinga yomoya kwaye iphele ichaphazela indalo kunye noluntu, ngaphezulu okanye ngaphantsi. Kwimeko ye-volumbano yaseCumbre Vieja, kungabakho ilifu leegesi eliza kufikelela usingasiqithi. Nangona kunjalo, amandla okuphela aneegesi emoyeni njengoko zihamba zijolise koku kungabonakali ukuba okwangoku kungadala ingxaki enkulu kwindalo.
Ngaphantsi komhlaba wesiqithi, i Ungcoliseko lwamanzi amdaka ngokuphuma kweegesi kunokuba yenye yeziphumo zolu dubulo. Nangona kunjalo, ulawulo olungqongqo lwala manzi angaphantsi komhlaba kunye nolwazi oluchanekileyo kwezi zenza ukuba masingoyiki. Yintoni ekufuneka isixhalabisile yile umonakalo onokubangelwa luthuthu lwentaba-mlilo ebantwini, kwizilwanyana nakwizityalo Ezingaphakathi kwerediyo yayo yokusebenza.
Iziphumo zoqoqosho
Ukuqhuma kwentaba-mlilo kushiya icandelo lezolimo laseLa Palma kwimeko ebuthathaka kakhulu. Phakathi kwezityalo ezichaphazeleke kakhulu kukho iibhanana, iavokhado kunye nezidiliya. NgokukaMbutho weMibutho yabavelisi beBhanana kwiiCanary Islands, Iibhanana zivelisa i-50% ye-GDP yesiqithi. Kukho abavelisi abangaphezu kwama-5.300 kwesi siqithi kunye neentsapho ezingama-10.000 XNUMX ezixhomekeke ngqo kulimo lwazo.
Ukhenketho Inokonakaliswa ngelixa i-volcano isasebenza. KwiiCanary Islands eli lixesha eliphezulu. Uninzi luya kuhamba ukuya esiqithini ukuya kubukela indalo enje. Nangona kunjalo, olunye uhlobo lokhenketho luya kulahleka: olufuna uxolo kunye nokubaleka kubanda. Ukongeza, kunjalo, ilahleko yezoqoqosho kusapho ngalunye oluninzi kwikhaya lalo (okanye kwishishini elingcwatyelwe phantsi kwelala.
UMongameli woRhulumente weZiqithi zeCanary, u-Ángel Víctor Torres, sele ebhengezile ukuba isiGqeba siza kubamba Iimali zobumbano ze-EU ukuqala ngokutsha eLa Palma xa imeko kaxakeka iphela ngenxa yokuqhuma kwentaba-mlilo.
