Recent advances in large ring laser gyroscopes (RLG) technologies opened the possibility to observe rotations of the ground with sensitivities up to 10−11 rad/sec over the frequency band of seismological interest (0.01-1Hz), thus opening the way to a new geophysical discipline, i.e. rotational seismology. A measure of rotations in seismology is of fundamental interest for (a) the determination of all the six degrees of freedom that characterize a rigid body’s motion, and (b) the quantitative…

Rotational motions from the 2016, Central Italy seismic sequence, as observed by an underground ring laser gyroscope
We present the analysis of rotational and translational ground motions from earthquakes recorded during October-November 2016, in association with the Central Italy seismic sequence. We use
Deep underground rotation measurements: GINGERino ring laser gyroscope in Gran Sasso.
TLDR
First analysis of the correlation between the rotational and the translational signal is presented, and the power spectral density in the seismic bandwidth is at the level of 10-10 (rad/s)/Hz.
Observation by Means of An Underground Ring Laser Gyroscope of Love Waves Generated in the Mediterranean Sea: Source Direction and Comparison with Models
In fall 2018, we have observed, by means of an underground ring laser gyroscope, the microseismic (MS) activity induced by the Mediterranean Sea in the 2–5 s period range. In the amplitude spectra,
Monitoring Local Earthquakes in Central Italy Using 4C Single Station Data
TLDR
This study will explore the possibility to locate the hypocenter of local events by using a ring laser gyroscope observing the vertical ground rotation and a standard broadband seismometer to identify the first shear onset transversely polarized (SH).
First Results of GINGERino, a deep underground ringlaser
Large ring-laser gyroscopes are capable of measuring angular rotations with a precision well below fractions of $prad/s$, not far from $10^{-14}$ $rad/s$, the accuracy required for General Relativity
An Event Database for Rotational Seismology
TLDR
A new event database for rotational seismology is introduced to promote the use of joint rotational and translational ground-motion data demonstrating their potential for characterizing seismic wavefields.

A record of changes in the Gran Sasso groundwater before, during and after the 2016 Amatrice earthquake, central Italy
TLDR
Analysis of data recorded before, during and after the Amatrice earthquake revealed highly dynamic aquifer behaviour associated with the uprising of geogas probably related to the preparation stage of the Am atrice earthquake.
