Abstract
Some of the data for Earth tide observed near the sea have shown the strange results, contrary to our expectancy that the earth surface tilts chiefly with the tidal load of the sea water. We compare the both tidal variations in the discharge rates of hot springs and the observed anomalies of Earth tide in Beppu which were investigated in detail by Dr. E. NISHIMURA, and conclude that the main parts of the latter may originate from the variations in the thickness of the artesian aquifer with the tidal changes in the ground water pressure. It is, thus, inferred that.a few similar phenomena observed in Japan may also refer to the elastic deformation of the artesian aquifer.
