Tilt Precursors in Rock Before Failure: A Laboratory Investigation
Laboratory measurements of tilt precursors whose time durations are on the order of a few milliseconds are shown to precede failure in dry rock specimens measuring approximately 13 cm in length. The tilt behavior is qualitatively similar to that reported to precede earthquakes. Test results suggest that this precursor time for laboratory specimens of this length is independent of rock type, in agreement with theoretical predictions and other experimental data on rock failures including earthquakes.
