Abstract

We report hydraulic fracturing experiments conducted on 200 mm mortar cubic blocks with acoustic emissions registered and analysed using the Blue Shift Indicator algorithm. It reveals complex branching fracture geometry of fractal nature. Aftershocks are also observed in the experiments; the aftershock rate fits the Omori law.
