Paper Abstract

The paper presents a new telemetric system for direct measurement and investigation the rotational components exist in seismic events. The FORS - fiber optic rotational seismometer and seismographs constructed on the base of the Sagnac interferometer are the elements of the system. The special construction of the system protects their elements remote control in real time via internet utilize the GSP/GSM connections. The first results according application autonomous FORS (AFORS) with accuracy in the range 4.9·10-9 - 6.1·10-8 rad/s in detection bandpass 1.66 - 212.30 Hz located in Ksiαz and Warsaw, as well as older one FORS-II (mounted in Ojców) are reported.
