Abstract
For the purpose of finding out some clues for the earthquake prediction, continuous observations of crustal deformation with extensometers and tiltmeters at several stations have been carried out during about 20 years. Observational points are Oura, Donzurubo, Amagase and Iwakura, locating almost on a straight line in the SW-NE direction in the central part of the Kinki district. The ground-strains and -tilts were compared with seismic activities in the vicinity of each observatory. And it was found that the secular variations of the areal dilatations had the chara cteristic change in common to all stations, and that these changes moved with the velocity of about 30 km/year to the direction from SW to NE, that is, in order of Oura, Donzurubo, Amagase and Iwakura.
