ICampi Flegrei ngokuyinxenye ijikeleze isixeko saseNaples kwaye inabela ngasentshona kuLwandle lwaseTyrrhenian. Ukususela kumaxesha amaRoma, abantu baye baqaphela ukuba umhlaba uvukile kwaye uwile, kwaye ngokugrumba kwimbali yayo ye-geologic, izazinzulu ziye zafumanisa ixesha elidlulileyo le-volcano. Le caldera njengoko ibonakala namhlanje yakrolwa zii<em>paroxysm ezimbini ezinkulu ngendlela engenakucingelwa—enye kwiminyaka engama-36 000 eyadlulayo nenye kwiminyaka engama-15 000 eyadlulayo—eyagrumba umhlaba yaza yagubungela loo mmandla kwinkunkuma yentaba-mlilo.

Ukusukela ngoko, iCampi Flegrei iye yabamba ugqabhuko-dubulo oluncinane olungenakubaleka, oluhlala lubandakanya iziqhushumbisi kulo lonke i-caldera yalo ebanzi, emhlabeni naselwandle. Ukugqabhuka kwayo kokugqibela, emva ngo-1538, kwakha ikhowuni encinci kwisithuba seveki. Akukho magma entsha eyenzileyo phezulu ukusukela

Noko ke, ukususela phakathi kwinkulungwane yama-20, intaba-mlilo iye yaphazamiseka. Ngeminyaka yoo-1950, yoo-1970, kunye noo-1980, i-caldera yabandakanyeka kwizidubedube zeminyaka emibini yeziphithiphithi, itshintsha imilo ngokunyuka nokuthomalalisa, kunye nokungcangcazela kuthotho lweenyikima. Esona siganeko sibi kakhulu sasiphakathi ko-1982 no-1984, xa umhlaba waphakama ngeemitha ezintandathu kwaye, ngenxa yokoyika umonakalo wesakhiwo, abantu abangama-40,000 bedolophu yasePozzuoli baphuma.

Ngelo xesha, “abantu babengazi ncam ukuba balindele ntoni kuCampi Flegrei,” utsho njalo uMarzocchi. Ngenxa yogqabhuko-dubulo olukhulu lweNtaba iSt. Helens eUnited States olwalusenzeka kwiminyaka nje embalwa ngaphambilana, izidubedube zikaCampi Flegrei zathetha ukuba izazi ngentaba-mlilo zasekuhlaleni “zazinexhala kancinane.”

Kodwa emva kwezidubedube zaloo ntaba-mlilo, akuzange kugqabhuke—nto leyo eyayidida yaye isiqabu.
