Volcanoes yog ib tug vibrant manifestation ntawm phaj tectonics txheej txheem. Volcanoes muaj ntau nrog convergent thiab divergent phaj ciam teb . Volcanoes kuj yog pom hauv lithospheric daim hlau nyob deb ntawm phaj ciam teb . Volcanoes tawg vim mantle pob zeb melts.
Dhau li ntawm no, puas yog tag nrho cov roob hluav taws nyob rau ntawm daim phiaj ciam teb?
Feem ntau roob hluav taws form ntawm lub ciam teb ntawm lub ntiaj teb tectonic daim hlau . Volcanoes feem ntau muaj nyob rau hauv cov geologically nquag ciam teb . Ob hom ntawm phaj ciam teb uas feem ntau yuav tsim tau roob hluav taws kev ua yog txawv phaj ciam teb thiab convergent phaj ciam teb.
Ib tug kuj yuav nug, dab tsi volcanoes nyob rau ntawm convergent phaj ciam teb? Cascades yog cov saw ntawm roob hluav taws ntawm a convergent ciam teb qhov twg muaj dej hiav txwv phaj yog subducting hauv qab ib tug continental phaj . Tshwj xeeb cov roob hluav taws yog qhov tshwm sim ntawm subduction ntawm Juan de Fuca, Gorda, thiab Explorer Daim phiaj hauv qab North America.
Ua li no, yog vim li cas volcanoes pom nyob rau ntawm phaj ciam teb?
Volcanoes muaj ntau nrog tectonic phaj ciam teb qhov twg dej hiav txwv daim hlau tog hauv qab daim hlau . Raws li ib tug phaj sinks tob rau hauv ib cheeb tsam subduction, nws heats thiab pib yaj, tsim magma. Volcanoes kuj muaj raws li tectonic ciam teb qhov twg daim hlau rub sib nrug, cia magma sawv los ntawm lub mantle.
Hom phaj ciam teb yog eyjafjallajokull rau?
Cov ntaub ntawv kawm: kev tawg hauv lub tebchaws tsim - Eyjafjallajökull. Iceland muaj ob peb lub roob hluav taws thiab nyob rau ntawm ob daim phiaj tectonic - lub North American phaj thiab Eurasian phaj . Lub roob hluav taws, nyob rau thaj tsam Eastern Volcanic nyob rau sab qab teb Iceland , pib tawg lava rau 20 Lub Peb Hlis 2010.

Dab tsi ntawm daim phiaj ciam teb yog Philippines?
Philippine Sea Phaj. Lub Philippine Sea phaj yog tectonically txawv nyob rau hauv uas yuav luag tag nrho cov ciam teb yog convergent. Lub phaj Pacific yog subducting hauv qab Philippine Hiav Txwv Phaj mus rau sab hnub tuaj thaum sab hnub poob / qaum teb sab hnub poob ntawm Philippine Sea phaj yog subducting hauv qab lub continental Eurasian phaj
Cov volcanoes twg nyob rau ntawm convergent phaj ciam teb?
Volcanoes ntawm convergent phaj ciam teb yog pom nyob rau hauv lub Pacific hiav txwv phiab, feem ntau nyob rau ntawm ntug dej hiav txwv Pacific, Cocos, thiab Nazca daim hlau. Trenches cim subduction zones. Cov Cascades yog cov saw hlau ntawm cov hluav taws kub ntawm ib thaj tsam sib koom ua ke qhov twg cov phaj dej hiav txwv yog subducting hauv qab daim phiaj av
Dab tsi ntawm daim phiaj ciam teb ua rau muaj av qeeg hauv San Francisco xyoo 1906?
Pacific Phaj (nyob rau sab hnub poob) swb kab rov tav qaum teb sab hnub poob txheeb ze rau North American Phaj (nyob rau sab hnub tuaj), ua rau av qeeg raws San Andreas thiab muaj feem cuam tshuam. Lub San Andreas txhaum yog ib qho kev hloov pauv ntawm ciam teb, ua kom haum rau kab rov tav cov lus tsa suab
Dab tsi ntawm daim phiaj ciam teb yog av qeeg Kobe?
Av qeeg uas ntaus Kobe thaum lub caij ntuj no xyoo 1995 ntsuas qhov loj 7.2 ntawm Richter nplai (lossis 6.9 ntawm qhov ntsuas tam sim no ntau dua). Ntawm daim phiaj no, lub phaj Pacific tau raug thawb hauv qab Eurasian phaj, kev ntxhov siab tsim thiab thaum lawv tso lub ntiaj teb co co
Puas yog Mexico City nyob ze ntawm daim phiaj ciam teb?
Qhov ntawd rov ua av qeeg reverberated raws tus ciam teb ntawm Cocos thiab North American phaj raws li lub phaj sab qab teb-feem ntau plam hauv qab nws cov neeg nyob sab qaum teb thiab ntaus thaj tsam li 3 mais qaum teb sab hnub tuaj ntawm lub nroog Raboso. Mexico yog ib lub tebchaws uas muaj seismic tshaj plaws hauv ntiaj teb
