The structure and evolution of powerful H2O maser flares in the source IRAS 18316–0602 are studied using the results of observations on the 22-m radio telescope of the Pushchino Radio Astronomy Observatory. The main origin of the last powerful, short-term flare in 2017 may be the superposition of two maser condensations with very similar radial velocities along the line of sight. All powerful flares occurring in IRAS 18316–0602 since 2002 can be associated with a cluster of maser condensations whose radial velocities are in the interval 41.0–43.5 km/s. It is suggested that this may be related to turbulent, possibly vortical, motions of material in this region.
