抄録: A large change in the ground's resistivity associated with the Izu-Hanto-Toho-Oki Earthquake of M = 6.7 on June 29, 1980, was clearly recorded by a real time continuous telemeter system of the resistivity variometer at the laboratory of the Aburatsubo Crustal Deformation Observatory. The resistivity changes were recorded in two directions of N20°E and N74°W on the floor of the observation vault. No conspicuous precursory change such as the saw-tooth pattern to start about 4 hours prior to the coseismic resistivity change associated with the Izu-Hanto-Oki Earthquake of M = 6.9, May 9, 1974, was found on the records (see Figs. 2 and 4). However, it is most interesting to note in Figs. 2 and 4 that a new pattern of precursory resistivity change was observed associated with the main shock. This type of change, possibly classified as type IV, is characterized by a group of intemittent pulse-like changes superimposed on a box-car type change.
