  6. Fault strength evolution during the seismic cycle: Insights from the laboratory

    10 Mar 2023 | Contributor(s): John Bedford

    Geophysical evidence suggests that some faults are frictionally strong, in agreement with laboratory measurements of quasi-static frictional strength (μ ≈ 0.6-0.8) for many crustal materials; whereas others studies have found that some faults are weak when compared to laboratory friction...
