The electromagnetic field change in the ultra low-frequency (ULF) band was observed in order to investigate the precursory phenomena of crystal activity such as earthquakes, volcanic eruptions and landslides. The measurements are conducted to make cl

A simple-structured speed sensor in which a polarization-maintaining optical fiber is used as a Karman vortex generator and also as a vortex frequency sensor had earlier been proposed. For measuring ocean current velocity, a double-fin-type sensor mo
