Some US Parks that have active volcanoes formed as the result of subduction related processes are: 1  Crater Lake National Park, OR.
Most volcanoes occur along plate margins or at 'hotspots' in the earth's crust.Volcanoes are openings in the earth's crust that spew out molten lava,ash,steam and gas. Deep beneath every volcano lies a reservoir of molten rock called a magma chamber. just now. Report Abuse. Volcanoes occur where magma rises through the Earth's crust and reaches the surface. To do this, the magma must find a weakness in the crustal rocks on either the land or under the sea. Most of the volcanoes occur at, or close to, the edges of tectonic plates.
