A strong burst of star formation can result in the formation of up to ~10³ massive stars, which after a time of ~10⁶ yr will have supernova explosions. Depending on the spatial distribution of the supernovae, their combined effect will produce blast waves with different geometries. In this paper, we derive a solution for supernovae going off in a linear distribution (e.g., along a sector of aspiral arm) and also discuss the case of a planar distribution. Finally, we compare the results obtained for a centrally concentrated, a linear and a planar distribution for the supernovae.
