Magma will then only reach the surface along dikes propagated from these deep reservoirs, and such events will be infrequent and characterized by very large‐volume eruptions. These conditions favor the formation of sinuous rules, single long flows, and widespread flow units, rather than abundant small eruptions from a central edifice.
