Middle size ring-laser gyroscopes can be devoted to rotational seismology. Rotational seismology requires instrumentation able to provide long term operation with sensitivity close to nrad/s and suitable response in the frequency range from 0.01 to 100 Hz. Our GP2 prototype, have a simple and compact control apparatus and is suitable to be installed in common geophysical observatories. The RLG has remarkable long term stability, even in the ultra low frequencies (corresponding to periodes up to a few hours), which are outside the range of classical geophysical instrumentation. Such stability can also open perspective for geophysics, with, for instance, possible applications in volcanology. We are  collaborating with INGV to built TRIO, a Transportable RIng-laser Observatory.  TRIO is part of the STRIC project  (PNRR  Project Manager Unicam).
