We report the preliminary results of investigation of ionized and neutral gas structure, kinematics and emission spectra in the complex of a recent burst of star formation in the Irr Galaxy IC10 based on the observations made with the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences using MPFS field spectrograph and SCORPIO focal reducer operating in the Fabry-Perot interferometer mode. From FPI observations in the Hα and [SII](λ6717A˚) lines we estimate the expansion velocities of the two brightest shell-like nebulae HL111 and HL106 and reveal faint high-velocity features in the complex. An analysis of 21-cm line VLA observations of the galaxy allowed us to identify two local HI shells surrounding HL111 and HL106, and estimate their expansion velocities. We briefly discuss the emission spectra and the metallicity of the ionized gas in the galaxy.
