GINGER data analysis for seismology
Main Article Content
Abstract
Since several years, the ring laser gyroscope GINGERINO is operative inside the underground Gran Sasso laboratory. It monitors on a continuous basis the local Earth angular velocity in the horizontal plane. It provides unique information for geophysics in general, being one of the few top sensitivity angular velocity sensors. The present paper describes the analysis procedure developed for the data uploaded on the EIDA data base, suitable for seismological investigation in the frequency window 100 s up to 100 Hz. Typical errors and data quality will be discussed. This work is part of the data analysis tools under development for the GINGER project, a ring laser array, part of the UGSS (Underground Gran Sasso Seismology) multi components array at present in construction inside the Gran Sasso laboratory.
