Island arcs yog ntev chains ntawm cov volcanoes nquag nrog seismic kev ua si pom nyob rau hauv convergent tectonic phaj ciam teb(xws li lub nplhaib ntawm hluav taws). Feem ntau cov kob arcs pib ntawm dej hiav txwv crust thiab tau tshwm sim los ntawm qhovntsej thiaj tsis mob ntawm lithosphere mus rau hauv lub mantle raws thaj tsam subduction.
Txoj kev ciam teb yog dab tsi yog volcanic arc?
Thaum ob daim phiaj dej hiav txwv sib tsoo ib leeg, qhov loj dua thiab yog li hnyav dua ntawm ob lub subducts hauv qab ib leeg, pib ua volcanic ua haujlwm zoo ib yam li qhov tshwm sim ntawm dej hiav txwv-continental convergent phaj ciam teb thiab tsim ib lub roob hluav tawskob arc.
