Seismic traveltime maps computed with wavefront construction methods can exhibit gaps at isolated grid points, e.g., in the vicinity of caustic regions. For some applications like migration, these gaps can lead to problems. In this paper we suggest a method to fill the gaps. It is based on a hyperbolic traveltime expansion and leads to a simple formula for the estimated traveltime at the gap.
