Lua pele Etna

pele pele etna

Aia ma waena o nā lua pele ikaika loa o nā ʻāina āpau o ʻEulopa ka Lua pele Etna. Ua ʻike ʻia ʻo Mount Etna a he lua pele aia ia ma ke kapakai hikina o Sisilia ma ka hema o ʻItalia. Ua manaʻo ʻia ʻo ia ka luaipele hana nui loa ma ʻEulopa āpau mai ka hū ʻana i kēlā me kēia makahiki. He luaipele ia e huki ai i ka nui o ka mākaʻikaʻi a ʻo ia ke kumu waiwai nui o ka mokupuni.

Ma kēia ʻatikala e haʻi aku mākou iā ʻoe e pili ana i nā ʻano, nā pele a me nā ʻike ʻana o ka lua pele Etna.

Nā kuhikuhi nui

lua pele ma sicily

ʻO nā lua pele kēia ma luna o ke kūlanakauhale ʻo Catania ma ka mokupuni ʻo Sisily. Ke ulu nei ia ma kahi o 500.000 mau makahiki a loaʻa iā ia kahi moʻo o nā pele i hoʻomaka i ka makahiki 2001. Ua ʻike ia i kekahi mau pele, e like me nā pahū ikaika a me nā kahe pele nui. Noho ma mua o 25% o ka heluna kanaka o Sisilia e noho ana ma nā pali o ka mauna Etna, ʻo ia ke kumu waiwai nui no ka mokupuni, me ka mahiʻai (ma muli o kona lepo lua pele nui) a me ka mākaʻikaʻi.

Ma kahi kiʻekiʻena ʻoi aku ma mua o 3.300 mau mika, ʻo ia ka lua pele kiʻekiʻe loa a ākea ākea ma ka ʻāina ʻo ʻEulopa, ka mauna kiʻekiʻe loa ma ke kahawai Mediterranean a me ka mauna kiʻekiʻe loa ma Italia ma ka hema o nā kuahiwi. Nānā ʻole i ke kai ʻIonia ma ka hikina, ka muliwai ʻo Simito ma ke komohana a me ka hema, a ʻo ka muliwai ʻo Alcantara i ka ʻākau.

Uhi ka lua pele i kahi ma kahi o 1.600 kilomika kilomika, he anawaena kona wahi ma kahi o 35 mau kilomita mai ka ʻākau a ke kūkulu hema, kahi anapuni o ma kahi o 200 kilomita a me kahi leo ma kahi o 500 kilomika kilomika.

Mai ka ʻilikai a i ka piko o ke kuahiwi, he mea kupaianaha nā wahi a me nā wahi nohona, a me nā mea kupaianaha maoli. Hana kēia mau mea āpau i kēia wahi no nā mea hele wāwae, mea paʻi kiʻi, kūlohelohe, volcanologists, kūʻokoʻa ʻuhane a me nā mea aloha i ka honua a me ka paradaiso. Hōʻike ʻo Sisilia Hikina i nā ʻano ʻāina like ʻoleAkā mai kahi ʻike kālaihonua, hāʻawi ia i nā ʻano ʻokoʻa kupaianaha.

ʻO Geology lua pele ʻāina

lua pele etna

Hōʻike kona ʻano kālaihonua i ka hana o ka Lua Pele Etna mai ka hopena o ka Neogene (ʻo ia ka 2,6 miliona mau makahiki i hala). ʻOi aku ma mua o hoʻokahi o nā kikowaena hana o kēia lua pele. Hoʻokumu ʻia nā cones kekona ʻelua i nā māwae transverse mai ka waena a i nā ʻaoʻao. ʻO ke ʻano o ke kuahiwi i kēia manawa ka hopena o nā hana o ma kahi o ʻelua mau kikowaena pele nui.

Ma kahi mamao o 200 mau mile wale nō, e hele ana i nā panalāʻau o Messina, Catania a me Syracuse, aia he ʻelua mau papa tectonic ʻokoʻa me nā ʻano pōhaku ʻokoʻa loa, mai nā pōhaku metamorphic i nā pōhaku igneous a me nā sediment, kahi mahele subduction, nā hewa nui o ka ʻāina. ʻO ka mauna ʻo Etna, nā luaipele hana ma nā mokupuni ʻo Aeolian a me nā wahi o waho o nā hana lua pele kahiko ma ka pā o nā mauna Ibleos.

Aia kahi papa lepo sedimentary mānoanoa ma lalo o ka mauna Etna, a hiki i kahi kiʻekiʻe o 1.000 mau mika, e hana ana i ka mānoanoa o ka pōhaku luaipele. i hōʻiliʻili ʻia i loko o 500.000 mau makahiki ma kahi o 2.000 mau mika.

ʻO nā ʻaoʻao ʻākau a me komohana o nā pōhaku sedimentary ma ka lalo o ka lua pele ʻo ia nā kaʻina pālolo-turbidite Miocene (i hoʻokumu ʻia e nā kai e lawe ʻia e nā kai o ke kai), ʻoiai ʻo ka ʻaoʻao hema a me ka hikina he waiwai kai mai nā Pleistocene.

Ma ka ʻokoʻa, ma muli o ka hydrogeology o kēia lua pele, ʻoi aku ka momona o ka wahi ma ka wai ma mua o ke koena o Sisilia. I ka ʻoiaʻiʻo, permeable kiʻekiʻe ka pele, hana e like me kahi aquifer, a noho ma kahi kumu lepo ʻaʻohe porous, impermeable sedimentary base. Hiki iā mākou ke noʻonoʻo i ka mauna Etna ma ke ʻano he huahuakai nunui hiki ke omo i ka ua hoʻoilo a me ka hau hau. Hele kēia wai āpau ma waena o ke kino o ka luaipele a puka i waho i nā punawai, keu hoʻi ma kahi kokoke i ka pilina ma waena o nā pōhaku ʻaʻohe hiki ke hoʻopili ʻia.

ʻO nā pahū a me nā pā tectonic o ka lua pele Etna

Hū pele

Ma waena o 2002 a 2003, ua hoʻokuʻu ʻia ka nui o nā lehu pele i nā makahiki he nui i hala. hiki ke ʻike maʻalahi ʻia mai ke ākea, a i Libya, ma kēlā ʻaoʻao o ke Kaiwaenahonua.

ʻO ka hana Seismic i ka wā o ka pele i hoʻolalelale i ka ʻaoʻao hikina o ka luaipele i lalo i ʻelua mau mika, a he nui nā hale ma ka ʻaoʻao o ka luaipele i hōʻeha ʻia i nā ʻino. Ua hoʻopau loa ka pele i Rifugio Sapienza ma ka ʻaoʻao hema o ka lua pele.

Nui nā manaʻo e pili ana i ke kumu o ka hana o ka lua pele Etna. E like me nā lua pele Mediterranean e like me Stromboli a me Vesuvius, Aia ia ma ka palena subduction, a me ka pā o ka tectonic ʻApelika kipaku ʻia ia ma lalo o ka pā Eurasia. ʻOiai ua kokoke loa lākou i ka honua, ʻokoʻa maoli ka lua pele Etna mai nā luaipele ʻē aʻe. He ʻāpana maoli ia o kekahi puʻu pele lua pele ʻokoʻa. ʻO ka Etna, ma kahi o ka noho pololei ʻana i ka ciona subduction, noho maoli ia i mua ona.

Aia ma luna o ka hewa hana ma waena o ka una ʻApelika a me ka microplate Ionian, paheʻe pū lākou ma lalo o ka pā Eurasia. Hōʻike nā hōʻike o kēia manawa ua haki paha nā pā ionic māmā, a ua hoʻihoʻi ʻia kekahi o lākou e nā papa ʻoi loa o ʻAmelika. Hoʻopomo pololei ʻia ʻo Magma mai ka ʻahu o ka Honua e ka hakahaka i hana ʻia e ka papa ionic huki.

Hiki i kēia hanana ke wehewehe i ke ʻano o ka pele i hana ʻia e ka pele o Mount Etna, like me ke ʻano o ka pele i hana ʻia ma nā kahawai hohonu, kahi e hoʻokau ʻia ai ka magma o ka ʻahuʻula e hele i waena o ka pā. ʻO ka Lava mai nā lua pele ʻē aʻe o ke ʻano i hana ʻia e ka hoʻoheheʻe ʻana o ka pahu i kū ai ma mua o ka hū ʻana o ka ʻahu mantle.

Nāʻikepili

ʻO kekahi o nā hana hoihoi loa o kēia lua pele penei:

  • Hōʻike ʻia i kahi kiʻi ʻoniʻoni ʻo Star Wars
  • Nui nā hoʻāʻo e kāohi i nā kahe pele i hoʻoweliweli e luku i ke kūlanakauhale ʻo Catania.
  • He lua pele stratovolcano ia. Kuhi ʻia kēia ʻano lua pele ʻo kekahi o nā mea weliweli loa ma muli o kāna mau pele i pohā nui loa.
  • ʻO ka inoa o Etna "Puhi wau."
  • ʻO kekahi o nā pele mai ka lua pele he 300.000 mau makahiki.

Lana koʻu manaʻo me kēia ʻike hiki iā ʻoe ke aʻo hou aʻe e pili ana i ka lua pele Etna a me kona ʻano.


Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.

E lilo i mea mua e wehewehe

E waiho i kāu manaʻo

Kāu leka uila aae? E,ʻaʻole e paʻiʻia. i hāliu aku i koi 'ia kula *
