Monitoring of ULF
(ultra-low-frequency) Geomagnetic Variations Associated with Earthquakes
(Sensors 2007, 7, 1108-1122) Induction magnetometers installed at these two
stations are search coil type with 85 Hz sampling rate, named LEMI-30 produced by Lviv Center of Institute of Space Research,
National Academy of Science of Ukraine. These sensors are intended for the study
of frequency band from 0.01 to 30 Hz, and detailed specification of them is
summarized in Hattori et al. (2004) (7). Also the acoustic emission sensor was
installed at Matsushiro station. The acoustic sensor records the emissions at
four frequency bands of 30, 160, 500, and 1000Hz. The lowest band corresponds to the uppermost
frequency of LEMI-30.

Broadband
Magnetotelluric Instruments for Near-surface and Lithospheric Studies of
Electrical Conductivity: A Fennoscandian Pool of Magnetotelluric Instruments Geophysica (2008), 44(1-2), 31-44
In the AMT-MT mode (0.0011000 Hz), magnetic field components are
measured using three broadband induction coil magnetometers LEMI-120 from
Ukraine. In the LMT-mode (d.c. 10 s) the magnetic field is measured with a
three-component fluxgate magnetometer, also from Ukraine. In the Uppsala
instruments, MFS05-coils from Metronix are used instead of LEMI-120 coils
and a newer version of Lviv fluxgate magnetometers (suspended, water-proof) for
LMT. Electric field is measured in both cases with two electric dipoles of
normally 50250 m long and with Pb/PbCl2 electrodes.

and electronic unit, both located inside protective housing. The housing of the
search-coil magnetometer has tubular shape and is made of fibreglass tube with
inner electrostatic screen. Output cable of the magnetometer has the connector
for the coupling to the registration unit. Schematic diagram of the LEMI-106I
magnetometer is presented on Fig. 1. The LEMI-106I magnetometer
construction allows to use it onboard the spacecraft in space. It is designed to
