  Using approximate techniques we study the final moments of the collision of
two (individually non-spinnning) black holes which inspiral into each other.
The approximation is based on treating the whole space-time as a single
distorted black hole. We obtain estimates for the radiated energy, angular
momentum and waveforms for the gravitational waves produced in such a
collision. The results can be of interest for analyzing the data that will be
forthcoming from gravitational wave interferometric detectors, like the LIGO,
GEO, LISA, VIRGO and TAMA projects.
