subducted tectonic plate beneath the ring of fire code example

Example: Why does the Circum-Pacific belt of earthquakes coincide with the Pacific ring of fire

The abundance of volcanoes and earthquakes along the Ring of Fire is caused by
the amount of movement of tectonic plates in the area.
Along much of the Ring of Fire, plates overlap at convergent boundaries called
subduction zones.
That is, the plate that is underneath is pushed down, or subducted, by the plate
above.
