The National Research Center for Disaster Prevention is conducting the crustal tilt observation in the Kanto-Tokai area by using the borehole-type tiltmeters. The tiltmeter is installed at the bottom of the observation well. The output signal, which is proportional to the ground tilting, is transmitted to the Research Center at Tsukuba, Ibaraki Prefecture, by the telemetery system, and recorded on magnetic tapes by the real-time processor. In 1982, the observation was started at four stations in addition to the eleven stations where the stationary observation had been carried out since 1978. We report changes of the crustal tilt at the fifteen stations during 1982. The results are illustrated in two different types of diagrams : monthly diagrams (Fig.5) where tilt data are plotted every hour, and annual diagrams (Fig.4) where daily means of tilt data are plotted in order to show gross features of tilt changes.
