Introduction.

Abstract

• Often, volcanic activity results in the formation of volcanic fields rather than single large volcanic edifices. • Volcanic fields comprise small volcanoes (usually with volumes less than 1 km3), such as cinder cones, maars, tuff cones, tuff rings, small shield volcanoes, and lava domes. • Over periods of hundreds of thousands to millions of years, monogenetic volcanic activity can result in areally extensive volcanic fields consisting of hundreds to thousands of individual volcanoes and cumulative volumes approaching those of individual composite volcanoes.
