Abstract
The present work describes preliminary results of the analisys carried out on the signals provided by a rotational seismometer installed in the Campi Flegrei volcanic area. Starting from January 2021, a rotational seismometer (Lu nitek Tellus R2) was installed in the area. The analyzed data consists of 20 local earthquakes occurred in Campi Flegrei from February 2021. The local seismicity is composed by low magnitude volcano tectonic earthquakes (MDmax =3.6) located at depth between 0.3 and 4 km b.s.l. For the strongest earthquake, we observed a maximum rotational velocity equal to 6 mrad/s. The joint use of the rotational sensor and the accelerometer confirms the possibility of estimating the azimuth and the apparent velocity of the incoming wavefront and highlighted some more correlated phases in the coda of seismograms that could provide useful indications about the diffuse wave field recorded in the investigated area.
