Sakhalin island arc
Sakhalin island arc
is an ancient
volcanic arc
dating from the
Early Miocene
. The arc was a result of the
Okhotsk Plate
subducting beneath the
Eurasian plate
in the
convergence
zone. The arc runs from mainland
Asia
through
Sakhalin Island
into central
Hokkaido
and the collision zone around the
Daisetsuzan Volcanic Group
, where the
Kurile island arc
and the
Northeastern Japan Arc
meet.
