Abstract
The relation between the seiche in Aburatsubo Bay and the concerning crustal tilt atthe Aburatsubo Observatory has been already reported in the previous paper [1]. Four sets of TEM-tiltmeters [2, 3] measured tilt, while the seiche observation was made by using a pressure type tide-gauge during the period from February to May, 1979. The ratio of tilt and seiche amplitude is empirically determined as a function of the distance from the coast line on the basis of the results of observations. That is T=C exp (-λD), where T is the tilt-Seiche ratio (10-5 sec. of arc/mm), C=11.7, λ=0.0135 (meter-1) and D is the distance (meter) from the coast line. Although the observed ratios are greater than the theoretical one by factors of 1.2-1.3, the azimuths of maximum tilt agree well at each tilt observation site .
