Australia gudaheeda, ma jiraan meelo firfircoon: qaaradda ayaa "ku nasanaya" meel adag, sidaas darteed ma jirto dhaqdhaqaaq qulquleed oo Australiya ah ilaa 1.5 milyan oo sanno - marka laga reebo Polynesia, deriska ugu dhow ee Australia, halkaas oo ah meelaha ugu sareeya caalamka Mauna Loa iyo Mauna Kea .
Miyuu jiraa Volcanoes Australiya ah?
Australiya, volcanoes firfircoon ee "derisyada" ayaa bixiya dhibaatooyin yar - caaqilada kaliya waxay gaareen dhul-beereedka. Waxa kaliya ee saameyn kara dhaqdhaqaaqa tectonic ee volcanoes ee agagaarka dhul-beereedka waa soo saaridda gaas ka soo shelf xeebta.
Haddii aad tixgeliso Australia inaadan ahayn qaarad, laakiin dowlad ahaan, waa inaad xusuusataa in ay ku jirto jasiiradaha of Polynesia iyo Oceania. Sidaa darteed, jawaabta su'aasha ah "Miyuu jiraa walaaqo Australiya ah" waxay noqon doontaa mid wanaagsan. Laakiin liiska wicitaanada dab-damiska Australiya waa mid aad u ballaaran; waxaa ka mid ah 18 volcanoes, sida Atherton (oo ku yaal xaafaddiisa maanta waa magaala Atherton, kanalkan yar ayaa dhawaan la dhisay - oo keliya 100 kun oo sano ka hor), Barrin iyo Ichem (oo ah qaboojiyayaashu waxay leeyihiin magac isku mid ah), Hillsborough, Bundaberg iyo kuwo kale.
Mawson
4000 km oo ka soo jeeda Australia waa jasiiradda Volcanic of Heard, taas oo ah basaltel stratovolcano Mawson (wuxuu leeyahay magac kale - "Big Ben"). Mawson waa firfircoon firfircoon: qarxinteedii waxaa la diiwaan geliyay 1881, 1910, 1950-1954, 1984-1985, 1993, 2000. Dembiyada ugu dambeeyay ee dhacay waxay ka dhaceen Maajo 2006 ilaa November 2007.
Magaca Mawson oo lagu magacaabo geologist Australian, baadigoobka Antarctica Douglas Mawson. Volcano-kan wuxuu ka sara maraa heerarka badda ilaa dhererka 2745 m (waa meesha ugu sarraysa ee gobolka Australia). Atshmus cidhiidhi ah Mawson ku xiran dooxada dariska ah Dickson.
Wareegga hoose ee volcanoes ee qaarada Australia
Sannadkii 2015, daabacaadda Cnet ayaa daabacday natiijooyinka ay heshay kooxda cilmi-baarista ee uu hoggaaminayo Rodi Davis: Australia waxaa laga helay adduunka ugu dheer caalamka ee volcanoes, oo qarsoodi ah oo qarsoodi ah. Dhererka silsiladda waa 2 kun oo kilomitir, waa qiyaastii 2 jeer ka weyn dhererka silsiladda subterranean ee Yellowstone.
Silsiladda volcanoes, oo heshay magaca gabay "Roogga Dabka," ayaa ka gudbay qaybta bariga ee dhulka intiisa badan. Waxaa loo sameeyay sababtoo ah marinka qaaradda (inta lagu guda jiro isbeddelka) ee ku saabsan barta dooxada firfircoon ee dunada. Dhererka kaliya maaha mid xiisaha leh ee "Campfire Trail": waxa kale oo uu ku yaalaa mid ku filan saxanka tiyaatarka ah ee qaarada Australiya ku hareeraysan yihiin, sidaas daraadeed silsiladda soo jiidata waxay kor u qaadaysaa feejignaanta saynisyahanka: waxay aaminsan yihiin in daraasaddeedu ay nadiifin karto hababka dhaqdhaqaaqyada qaaradda.
Jasiiradaha Volcanic ee Australia
770 km u jirta Sydney waa jasiiradda Volcanic ee Lord Howe, oo ah jasiiradda ugu da'da weyn ee Badweynta Baasifigga; waxaa la sameeyay iyadoo ay sabab u tahay mideynta labada jasiiradood ee volcanka. In 20 km ka waxaa ka jira jasiirad fuushan oo kale, Bols-Pyramid (labada jasiiradood ayaa la furay hal mar, 1788). Bol-Pyramid waa kan ugu sarreeya dhammaan buuraha daaqadaha ah, dhererkoodu waa 562 m oo ka sarreysa heerka badda. Maanta jasiiraddu waa qayb ka mid ah Lord Howe Marine Park.
