ʻO kekahi luaʻi lua pele i Iceland hiki ke hana i nā haunaele o ka ea holo honua

Ke kani ala nei nā mea seismologists o Iceland e pili ana i ka piʻi ʻana o ka pae hoʻoweliweli no ka lua pele ʻo Grimsvotn i ʻike ʻia i kahi pele nui i 2011, e kī ana i kahi kia 20km o ka lehu i ka lewa.

I kēia manawa ke ao aku nei ka poʻe ʻepekema he nui nā hōʻailona e hiki koke mai ana kekahi pele hou.

I kēia mau lā, ua ʻike ʻia ka "hoʻāhu" ʻana o ka luaipele i ke komo hou ʻana o ka magma hou i nā keʻena ma lalo hou, a ʻo ka hopena o ka hoʻonui ʻana i ka hana mehana i hoʻoheheʻe ʻia ka hau. Ua hoʻonui ʻia ka hana ʻōlaʻi kūloko, nā mea āpau e hoʻohui nei e hōʻike e hiki koke mai kahi pele. 

Ke nānā nei nā Seismologists i kēia manawa no kahi ōlaʻi nui o ke ōlaʻi, hiki ke hala i 10 mau hola, e hōʻailona ana i ka lele o ka magma i luna a me kahi pele e hiki koke mai ana. 

ʻOiai he hiki wīwī, kahi hanana pele o kahi pālākiō i like me 2011 e hoʻonui i kahi kūlana weliweli no ka ʻoihana mokulele i hammered e ka maʻi ahulau coronavirus.

I ka makahiki 2010 ka hū ʻana o kekahi luaipele Iceland, ʻo Eyjafjallajokull, i hoʻokau aku ai i ka hoʻokahuli ʻia ʻana o kekahi mau mokulele he 100,000 i loko o kahi haunaele o ka holo ʻana o ka lewa honua ma mua. 

Ua ʻike ka lua pele ʻo Grimsvotn ma kahi o 65 mau pele i loko o 800 mau makahiki i hala iho nei, e hoʻolilo nei i ka luaipele ʻoi loa o ka ʻāina. 

Aia nā hakahaka maʻamau o ʻehā a 15 mau makahiki ma waena o nā pele liʻiliʻi, ʻoi aku ka nui o nā pele i kēia 150 a 200 mau makahiki, me nā hanana nui i hoʻopaʻa ʻia ma 2011, 1873, 1619.

Ua hoʻonui nui ʻia ka hoʻomehana wela mai ka lua pele i nā mahina i hala iho nei, e hāpai ana i ka piʻi ʻana o ka pae makaʻala, a kiʻekiʻe loa i kēia manawa, e hoʻoheheʻe ana i ka hau a puni a hana i kahi loko huna wai meltwater he 100 mau mika ka hohonu ma lalo o ka 260-mika mānoanoa. ma luna.

Hāʻawi kēia i kahi makaʻu i nā ʻoihana kokoke e hiki ai i ka meltwater ke pakele me ka ʻole o ka ʻōlelo aʻoaʻo, ke hele nei i loko o nā ʻāpana pele ma lalo o ka honua i mua o ka puka ʻana mai 45km. Ke nānā ʻia nei ka hele ʻana o ka wai ma waena o kēia mau tunnels i mea e pale aku ai i ka lilo o ke ola ke hiki mai nā kahe hāwanawana. 

Eia nō naʻe, ʻo kēia mau hanana wai hikiwawe e hōʻemi loa i ka kaomi ma ka lua pele a hiki ke hoʻomaka i kahi pele i puhi ʻia. 

Me ke aloha, ma ke ʻano he hopena o ka hau i luna o ka lua pele, a me ka waihona wai hoʻoheheʻe ma lalo, e pulu koke ka lehu e puka mai ana mai ka lua pele. 

ʻOiai e loaʻa ana kekahi haunaele i ka huakaʻi ea, lana ka manaʻo ʻaʻole ia ma ka pālākiō o ka hanana Eyjafjallajokull, ʻoiai ʻo ka hana lua pele ka mea paʻakikī e wānana e like me ka mea i hōʻike ʻia e ka pele 2010 i paʻa i ka honua mai ke kiaʻi ʻole.
