Abstract
The inclusion theory of failure predicts that seismicity precursors (seismicity increase followed by seismicity decrease in the immediate vicinity of an impending failure) will precede failure. A precursor is defined as an effect produced within a physical system which indicates that the process leading to failure of the system has begun. A key prediction of the inclusion theory is that the process of failure is scale invariant, or simply, the same physical processes are operative on the small scale (laboratory), intermediate scale (mine failure), and large scale (earthquake). This Bureau of Mines paper presents experimental evidence showing that anomalous seismicity precedes failures of rock on the laboratory scale, rock bursts in mines, and earthquakes.
