“…Zhang et al (2017) similarly show that earthquake-induced changes in permeability can explain changes in water level near the Three Gorges, China, after that same earthquake. Sarychikhina et al (2018) compare groundwater level and temperature changes with ground deformation recorded before and after a magnitude 5.4 earthquake and its foreshock and aftershocks in the Mexicali Valley of Baja California, Mexico. They attribute the co-seismic water level changes to static volumetric strains caused by the main shock, except in one well, where the water level change may have been affected also by a triggered slip event on a nearby fault.…”
