This paper develops a new method for evaluating rock mass slope stability by using the remote sensing on the ground, and reports the results of applying the method to an actual slope. The slope consists of andesite which has various degrees of weathering. We observe the spectral reflectance and temperature of the slope surface. According to the characteristic of temperature, the slope surface is divided into many areas. At each area, we calculate La b values from the observed spectral reflectance. At each area, we measure the seismic wave velocity of slope surface and the ultrasonic wave velocity of rock blocks. From the experimental relationship between the b value and the seismic wave velocity, etc., it is possible to estimate the seismic wave velocity of slope surface and the ultrasonic wave velocity from the observed b value. When getting the seismic velocity, etc., we can estimate the slope stability by using the conventional relationships. This result shows the possibility that we can evaluate the stability of rock mass slope, based on the remote sensing technique.
