'''Mafic volcanoes''' typically erupt for brief time intervals (weeks to perhaps centuries), but some can grow almost as large as composite [[volcano|volcanoes]]. Subsequent eruptions in the region typically issue from new vents and, over tens to hundreds of thousands of years, build broad fields of many volcanoes.
