Four mechanisms have been proposed to explain the structures and large scale mass motions of HII regions: the Champagne model, the ‘classical’ picture of an expanding Strömgren sphere, interaction of stellar winds and supernova blast waves with the surrounding medium. Especially the last three models have been used to explain the LMC shell structures. Braunsfurth et al. (1983) showed that it is not possible to distinguish the driving mechanisms for individual regions from their global appearance (dimension). Detailed studies of individual shells however, have been limited to the largest and brightest (30 Dor) or the more symmetric ones (e.g. N70, rings around WR stars).
