Pacific Ring of Fire iphi na yaye kutheni ibizwa ngokuba

Pacific Ring of Fire - negqiza mlilo, enyanisweni, ngasinye eliya kusebenza. Bonke bephela erhangqwe kolwandle, ukusuka apho ufumana igama layo. Phakathi kwazo kukho imigqomo yamanzi, apho, ngokutsho izazinzulu, kakhulu mlilo eziyingozi kakhulu. Qikelela iqhuma zabo phantse akunakwenzeka.

Apho na?

Ring of Fire yi ariya ibekwe kwi kujikelezo igama elifanayo yolwandle. Kukho ezininzi mlilo. Zonke ezo zikwi planethi kukho 540 - zezo ezaziwa eluntwini. Phakathi kwabo 328 ibekwe ngqo kwi ring ngomlilo.

Ubude nendawo le meko zendalo:

• entshonalanga - ukuqalela eKamchatka peninsula, ucanda i yaseJapan, bakwiiPhilippines kunye Kuril Islands, ithumba New Guinea, New Zealand. Oku kuphelela e Antarctica. Apha mlilo musa isebenze. aba bahamba yi-ice ikepusi, ngenxa yoko abazange le ntlekele;
• empumalanga - iqala kumantla Antarctica, udlula kwisiqithi ka Tierra del Fuego, i Andes Cordillera kunye Aleutians.

Nangona ukubandakanya esezantsi zendawo, inani mlilo kuzo zombini iindawo nama enye, kanye ukuba babetyala ngakumbi enabantu empumalanga.

Ezinye kweegiza ezincinane mlilo afumaneka kwi ezininzi ezincinane kwiziqithi Pacific Ocean.

Uvela njani?

ring umlilo pacific wabumba iinkqubo geodynamic ngenxa ezifana ekusasazeni kunye subduction. Bona imele lokukhula lithosfere yolwandle, xa amacwecwe ziqala ukuba kude omnye komnye, okanye icala Ukusiwa nemàbhula. Ngenxa yoko, i-mlilo bazalwa. ndawo ngoko nangoko Pacific kuquka ikhokhonathi kunye Nazca nembasa. Baya ifreyimi amazwekazi. Ngaphezu kubo, mlilo kwasekwa, kuba kwezi ndawo, amalungu lezitya amazwekazi.

Pacific isangqa lomlilo ayiphelelanga. Kwezinye iindawo, le nkqubo ingentla zange wathi, ngoko akukho mlilo nje kwakhiwa. Oku yabhiyozelwa lekhefu phakathi New Zealand kunye kunxweme Antarctica. Ngoko ke umsebenzi eliphezulu ephantsi wenyikima, ngoko akukho inyikima, kwakunye mlilo ayikwazi kuyilwa okanye, umzekelo, imigqomo yamanzi.

Kwakhona ngenxa yesi sizathu, ziintshukumo zenyikima liyasetyenziswa kwi emideni North America. "Ukuzola" umgca uhamba nxamnye California aze aye emantla ukuya eVancouver Island.

Bona ngqo mlilo kwasekwa ngokuthe ngcembe, kwiindawo plate interface. Kwaye ke amanzi epholileyo Pacific Ocean kubadlisa ukuba isebenze lonke ixesha, nto leyo kakhulu yingozi kubahlali zaloo mmandla.

ring Disasters umlilo

Mlilo the Pacific Ring yoMlilo i lembandezelo kakhulu, kwaye nenkathazo wazisa abantu Japan. Eyona idumileyo, ibekwe kule ndawo, Fuji. It is a cone kunye ubude km 4. Mlilo kwenzeka ngokufuthi, ukuba zihamba kunye udubulo isici. Enye iingozi ezininzi eziqatha yenzeka ngoDisemba 1707. Okokuqala, phezu mlilo kwabakho ilifu elimnyama yomsi nothuthu. Kwakusekumnyama ngathi ebusuku. Baza baqala ukuba off ngamatye kunye nothuthu evela kuyo. Ubunzima ndihlanjwe ezininzi kwiilali ezincinane, waziqhekeza ehlathini, intsimi ekuvuneni baba ephanzileyo ngokupheleleyo.

ekupheleni kukaSeptemba 1952 enye ingozi yenzekile eTokyo. Apha mlilo kwamanzi isaqhuma. izibini kuqala kancinci betekisi ash ngaphandle. Kwafika kuwa ekuthiwa-mlilo. Kwasekwa umthombo omkhulu. Zibulawa - abasemagunyeni wathumela kwindawo inqanawa sophando iphele. AmaNgqina kwezinye iinqanawa eyayihamba elidlulileyo, wathetha ngalo loo phezu kwamanzi kwakhiwa nemisele yamanzi, apho nangoko wanyamalala.

In Alaska kwaye i Aleutian Islands, apho yolula isangqa mlilo Pacific umlilo nayo ingaqhelekanga, njengoko kukho mlilo ngaphezu kwama-50. Kwenzeke ingozi embi apha ngo-1912, xa umthamo ash betekisi mlilo ka 8.5 kwiikhilomitha cubic. Ubunzima kwakhona eyayilingana iitoni ezingama-29 billion ukuya. Le yenye ntlekele enkulu mlilo.

Island of mlilo

Uphi na ke Pacific Ring yoMlilo, kukho kusoloko siqithi entsha, amazwekazi ezandisiweyo. Shintsho olwenziwa phantsi kwekhwapha lamanzi nokuba zincinane kakhulu (Shift ka 50-180 mm ngonyaka), ukuba umntu akwazi ukubamba ngaphandle izixhobo ezikhethekileyo.

imvelaphi mlilo ezendeleyo kwiintaba Loa kunye IKilauea, ukuba ibekwe Hawaii. Xa kukho kukujaduka, amanzi kufutshane kubo uqala ibile amagwebu. Imbonakalo ilifu umphunga ugalelwe luthuthu.

E eSumatra, i-Malay Archipelago uye 18 iziqithi mlilo. iimpawu zabo namachibi. Loo akafumaneki naphi na kwi planethi.

isiphelo

Ngenxa yoko, i-Pacific Ring lomlilo abachaphazeleka ngqo kulo ukuyilwa amazwekazi ezintsha. Kwenzeka kancinane kakhulu, kodwa zonke mlilo wobuso iyatshintsha. Ngoko ke, ulwandle akunjalo "tu".
