The acoustic emission b value is an important and widely used parameter for the early prediction of rock fractures. In this study, five groups true triaxial compression tests were conducted on granite specimens to analyze changes in during process failure, investigate characteristics events. First, events that simultaneously triggered at least four sensors located using P-wave arrivals sensor c...

We introduce a novel approach to estimate the temporal variation of b-value parameter Gutenberg–Richter law, based on weighted likelihood approach. This methodology allows estimating full history available data, within data-driven setting. test this against classical “rolling window” using high-definition Italian seismic catalogue as well global high magnitudes. The outperforms competing method...
