However, when considered over smaller timescales, the actual underlying relationship is likely to be non-linear, and may involve step changes in behavior at different levels of rainfall (i.e. threshold-based behavior). The aim of this study is to evaluate the ways in which...

... ABSTRACT: Rock mechanics researchers have defined crack initiation (CI) and crack damage (CD) thresholds as the points at which microcracks begin to propagate and coalesce under increasing stress levels. CI and CD correspond to cracking events and can be identified using Acoustic Emissions (AE...

... Long Short-Term Memory (LSTM) architecture is employed, with an adjusting threshold for the ground displacement hazard specific to Seville. Consequently, the threshold was systematically modified, ranging from 0.5 to 10 cm. The area under the curve (AUC) values for the 1 and 2 cm thresholds are 0.937...

..., and peak stress—are critical stress thresholds that influence the deformation and failure of brittle rocks under compression. Internal fissures in the rock release strain energy as transient elastic waves, leading to acoustic emission (Lockner, 1993; Turcotte et al., 2003; Wang et al., 2021; Sun et al...
