Abstract

In the paper new results connected with application of the fiber-optic Sagnac interferometer in the area of investigation of special seismic events are discussed. The device presented in the paper is designed for investigation of rotational component existing in the earthquakes called seismic rotation waves. Generally it is a fiber-optic rotational seismometer (FORS) based on its resolution in the range of 10xE-8 rad/s which can detect the seismic rotation waves in a direct way. The paper describes the first results obtained on the base of data recorded in Ojcow standard seismic observatory. The presented discussion in paper shows a new aspect connected with physical fundamentals of the seismic rotation waves.
