Thermal distribution at the 1-m depth under the ground surface has been measured using thermister in the Owakidani Landslide Area, Hakone. Areas of high temperature over 60°C are distributed in the zones of O. P, Q, Q′, R, R′ and S. It is observed that except those of R′ and S the zones have moved gradually since 1963 when the sruvey was started. The southern parts of the zones of Q. and Q′ have moved toward the upper (southern) parts of slopes with 20-30°. The zones of O and P have expanded or moved along the fault running from the north to the south. Due to these movements the zones with change have expanded gradually causing an increase of the instability of the slopes.
