Popis:	The full knowledge of the state of stress in the earth' s crust is indispensable for earthquake prediction research. Today, the crustal stress is measured only intermittently at limited sites by several methods, but not continuously. There are some difficulties in measuring the crustal stress (and not strain) continuously and monitoring its variation with time. The main reason is the fundamental lack of any effective method, because we have to know quantitatively the anisotropic deformation of the measuring device due to anisotropic crustal stress. A comment is presented on a proposed method for continuous stress measurement by a stress meter composed of a disk-shaped pressure vessel filled with liquid.
