Regular monitoring
of some geophysical parameters in association with seismicity has been
carried out since last year at the Japan-Russian Complex Geophysical
Observatory in the Kamchatka region. This observatory was organized in
connection with the ISTC project in Russia and was motivated by the
results of the FRONTIER/RIKEN and FRONTIER/NASDA research projects in
Japan. The main purpose of the observations is to investigate the
electromagnetic and acoustic phenomena induced by the lithosphere
processes (especially by seismic activity). The seismicity of the
Kamchatka area is analyzed and a description of the observatory equipment
is presented. At present, the activity of the observatory includes the
seismic (frequency range ∆F = 0.5 – 40 Hz) and meteorological
recordings, together with seismo-acoustic (∆F = 30 – 1000 Hz)
and electromagnetic observations: three-component magnetic ULF variations
( ∆F = 0.003 – 30 Hz), three-component electric potential
variations ( ∆F <u><</u> 1.0 Hz), and VLF transmitter’s
signal perturbations ( ∆F ~ 10 – 40 kHz).
