We consider an inverse problem for an inhomogeneous wave equation withdiscrete-in-time sources, modeling a seismic rupture. We assume that thesources occur along a path with subsonic velocity, and that data are collectedover time on some detection surface. We explore the question of uniqueness forthese problems, show how to recover the times and locations of sourcesmicrolocally, and then reconstruct the smooth part of the source assuming thatit is the same at each source location.
