Nyob rau hauv teb chaws Australia, tsis muaj kev kub ntxhov ntawm lub teb chaws: lub teb chaws yog "so" rau ib qho khoom lag luam, yog li tsis muaj kev ua si hauv Australia rau li 1.5 lab lub xyoo - tsis zoo li Polynesia, Australia tus ze tshaj neeg nyob, qhov twg lub ntiaj teb siab volcanoes Mauna Loa thiab Mauna Kea .
Puas muaj cov volcanoes hauv Australia?
Australia, lub pob zeb volcanoes ntawm "cov neeg nyob ib ncig" xa ntau yam teeb meem - tsuas yog cov neeg tuaj yeem ncav cuag lub mainland. Qhov tsuas yog qhov uas yuav cuam tshuam rau kev ua haujlwm tectonic ntawm volcanoes hauv cheeb tsam ntawm lub mainland yog lub extraction ntawm roj los ntawm ntug hiav txwv dej.
Yog tias koj xav txog Australia tsis yog ib lub teb chaws, tab sis raws li lub xeev, koj yuav tsum nco ntsoov tias nws muaj cov Islands tuaj ntawm Polynesia thiab Oceania. Yog li, lo lus teb rau lo lus nug "Puas muaj cov volcanoes hauv Australia" yuav zoo. Tab sis cov npe ntawm cov hluav taws nyob hauv teb chaws Australia muaj ntau heev; nws muaj 18 volcanoes, xws li Atherton (nyob rau ntawm nws qhov chaw siab tshaj hnub no yog lub nroog Atherton, lub roob hluav taws no tau nyuam qhuav dhau - nyuam qhuav muaj 100 txhiab xyoo dhau los), Barrin thiab Ichem (nyob rau hauv lawv cov craters tam sim no muaj lub npe ntawm lub pas dej), Hillsborough, Bundaberg thiab lwm tus.
Mawson
4000 km ntawm Australia yog volcanic island of Heard, uas yog ib tug basalt stratovolcano Mawson (nws muaj lwm lub npe - "Loj Ben"). Mawson yog ib lub roob hluav taws (active volcano): nws cov pob tawg yog kaw hauv 1881, 1910, 1950-1954, 1984-1985, 1993, 2000. Qhov kawg rau hnub tshwm sim ntawm Tsib Hlis 2006 mus txog rau Lub Kaum Ib Hlis 2007.
Lub npe hu ua Mawson nyob rau ntawm tus kws qhia txog Australian geologist, tus kws tshawb fawb ntawm Antarctica Douglas Mawson. Lub roob hluav taws no nce saum hiav txwv theem siab txog qhov siab ntawm 2745 m (yog lub siab tshaj plaws ntawm lub xeev Australia). Ib qho nqes isthmus txuas Mawson nrog lub Dickson neighboring lub roob hluav taws.
Underground Circuit Court ntawm volcanoes nyob rau sab av teb chaws Australia
Nyob rau xyoo 2015, cov ntawv xov xwm Cnet tau luam tawm cov ntsiab lus tau los ntawm cov pab pawg neeg tshawb fawb los ntawm Rodi Davis: Australia tau pom lub ntiaj teb ntev tshaj plaws ntawm cov hluav taws xob ntawm volcanoes, uas zais tob hauv lub ntiaj teb ua kaub puab. Qhov ntev ntawm cov saw yog 2 txhiab mais, nws yog 2 zaug ntau dua qhov ntev ntawm Yellowstone subterranean saw.
Lub saw ntawm volcanoes, uas tau txais lub npe hu ua "Txoj Kev Hluav Taws Xob," hla qhov feem ntawm sab hnub tuaj ntawm lub teb chaws loj kawg kiag. Nws tau tsim los ntawm cov khoom siv ntawm lub teb chaws (thaum lub sij hawm nws ua haujlwm) dhau qhov taw qhia volcanic nyob hauv lub ntiaj teb lub mantle. Qhov ntev ntev tsis yog qhov nthuav dav ntawm "Campfire Trail": nws tseem muaj nyob deb txaus los ntawm lub phaj tectonic uas cov teb chaws Australia sab nraud, yog li cov kev sib tham ntawm cov kws tshawb fawb: lawv ntseeg hais tias nws txoj kev tshawb no muaj peev xwm ua kom pom lub teeb ntawm cov txheej txheem ntawm cov teb chaws.
Volcanic Islands tuaj rau Australia
770 km ntawm Sydney yog lub kob volcanic ntawm Lord Howe, uas yog tus qub tshaj plaws volcanic kob ntawm Pacific hiav txwv; nws yog tsim los ntawm kev koom ua ke ntawm ob lub hiav txwv volcanic. Nyob rau hauv 20 km ntawm nws muaj ib kob volcanic, Bols-Pyramid (ob qho tib si Islands tau qhib ib txhij, hauv 1788). Lub Bol-Pyramid yog qhov siab tshaj plaws ntawm tag nrho volcanic cliffs, nws qhov siab ncov yog 562 m saum toj no hiav txwv theem. Hnub no lub koog yog ib feem ntawm tus Tswv Howe Marine Park.
