  GINGERino is a large frame laser gyroscope investigating the ground motion in
the most inner part of the underground international laboratory of the Gran
Sasso, in central Italy. It consists of a square ring laser with a $3.6$ m
side. Several days of continuous measurements have been collected, with the
apparatus running unattended. The power spectral density in the seismic
bandwidth is at the level of $10^{-10} \rm{(rad/s)/\sqrt{Hz}}$. A maximum
resolution of $30\,\rm{prad/s}$ is obtained with an integration time of few
hundred seconds. The ring laser routinely detects seismic rotations induced by
both regional earthquakes and teleseisms. A broadband seismic station is
installed on the same structure of the gyroscope. First analysis of the
correlation between the rotational and the translational signal are presented.
