Abstract
From the results so far arrived at with regard to mechanism of crustal movement as reveald in the tectonic pattern in East Asia, or the Northwest Pacific Tectonic Zone of the present writer (TATEIWA, 1976, 1979), he has come to understand in recent years that the tectonic pattern in question has originated in oroganic forces which have lifted into fold and pressed up the insular arcs, including the central arcs of Japanese Islands, toward the Pacific Ocean. In this paper, the fundamental conception of the writer, cited above, is emphasized by introdusing results of the well known paper experiments of Tokuda (TOKUDA, 1926-27, 1931, a) together with the detailed field observations by KRAUSKOPF and others on the Girloy slide, California, U. S. A. (KRAUSKOPF, et al. 1939).
