National Research Center for Disaster Prevention (NRCDP) constructed an observation network of ground tilting in Kanto-Tokai area, central Japan, for the purpose of earthquake prediction, by using borehole-type tiltmeters. We report the tilt changes at 20 stations of the network, obtained in 1985. The tiltmeters are installed at the bottom of observation wells, the standard depth of which is 100m except three deep wells. Output voltage proportional to ground tilting at each site is transmitted to the NRCDP by PCM telemetry system. The data are recorded on magnetic disk units by real time processors, and stored on magnetic tapes. We show daily means and hourly sampled data of the tilt changes in diagrams. For reference, we also plot daily precipitation at each station.
