Numerical models featuring diverse-scale rock bridges with LA:LB from 1.0:0.2 to 1.0:3.0, implemented by maintaining the length of rock bridge (A) (LA) as 25Â mm while increasing the length of rock bridge (B) (LB) from 5 to 75Â mm with an increment of 5Â mm. Three AE monitoring points evenly distribute across each rock bridge.
