A symposium on the mechanical properties of rocks was held by the Volcanological Society of Japan. Several papers by active investigators in an experimental field were presented. This paper is one of them and describes not only a general discussion on the mechanical properties of rocks but some recent results of rock creep. The contents of this paper are as follows: (1) Introduction. (2) Influence factor on the mechanical properties of rocks. (3) Types of deformation. (4) Creep characteristics of rocks and their analyses. (5) Mechanism of rock deformation. (6) Natural phenomena in the earth associated with the mechanical properties of rocks.
