Authors descrived here a procedure of quantitative interpretation on movement data from bubble tube tiltmeters.
Of principal component analysis using some characteristics on movement data, consequently composite magnitude can be evaluated by the first principal component score.
With a purpose of clarify the validity of two different element fractal dime nsion and cumulative ratio, we examined a simulation. As a result of comparison between culculated values and numerical values of real data, we proved that fractal dimension is to be closely related to the peculiarity of real data.
