Abstract

The most common test of breaking rocks in the laboratory under compression has provided the basis for most of the widely used modeling of faulting and the earthquake instability in the earth’s crust. But it has not been able to explain the actual complexity of fault systems insitu. However a greatly generalized lab experiment - widely overlooked for decades - provides the missing links needed to begin to understand the actual complexity of fault systems insitu.
