Physical simulation of ground fissures triggered by underground fault activity

► We perform physical simulation tests on ground fissures. ► We compare the fracturing modes of ground fissures and cracks on building. ► Ground fissures may be an old fracture surface having already spread to superficial layer covered by a very thin layer of loose soils. ► The over-pumping is just a factor to make the ground fissures exposed on the ground surface.
