Earth Strain and Acoustic Monitoring of Geodynamic Processes in Seismic and Aseismic Zones Using Highly Sensitive, Spatially Separated Instruments

Abstract

This paper reports results from observations of broadband geophysical processes using laser interferometer strainmeters and special acoustic instruments. We demonstrate examples of synchronous recordings of earth strain variations and geoacoustic oscillations of the ground surface in Kamchatka and in the Moscow Region, as well as results from a parallel analysis of these data, showing that the method proposed here can be used to separate local and global disturbances in these processes.
