The Ring of Fire isn't quite a circular ring. Partial melting of the subducted oceanic crust gives rise to andesitic volcanism parallel to the subduction zone. The water and gases in andesitic magma account for the explosive activity of andesitic volcanoes, which typically lie dormant for many hundreds or thousands of years.
