Studies in tectonophysics are becoming increasingly interdisciplinary: hence there was an attempt in this report to concentrate on subjects which have attracted particularly broad interest during this quadrinium, rather than on concentrating on the activities of the individual diciplines. One of the strongest debates during this period has been on the state of stress in the lithosphere, reported on by M. Zoback. This debate has centered on the conflict between the low heat flow over the San Andreas fault, which suggests very low stresses, and the experimentally determined laws of rock friction, which suggest the opposite. Other lines of evidence, such as that of shear heating in ductile shear zones, in‐situ stress measurements, and strengths necessary to support flexure of the lithosphere, and paleopeizometry have also been brought into the debate, all of which seem to support the latter point of view.
