Abstract

From latest foreighn reports concerning water-level fluctuations we learnt about the relations of physical parameters to phreatic level changes, and about the seismic relation also in comparison with hydroghraph data recoroed by a conventional recorder. The resuls is suggested that the level in a water well open to an artesian apuifer won't responods either to the changes of earth tide or to precursory phenomena of earthquake, because many of the apuifers in Japan have, in general, larger specific strage.
