Charmoille, A., Fabbri, O., Mudry, J., Guglielmi, Y. and Bertrand, C. (2005). Post-seismic permeability change in a shallow fractured aquifer following a M_L 5.1 earthquake (Fourbanne karst aquifer, Jura outermost thrust unit, eastern France). Geophysical Research Letters 32: doi: 10.1029/2005GL023859. issn: 0094-8276.

Following a ML 5.1 earthquake in eastern France, a post-seismic 12-day long electrical conductivity increase was recorded in the water discharging from a karst aquifer located 3 km from the epicentre. We attribute this to a permeability enhancement which allowed long-residence time water from low-permeability fractures located in the saturated zone to be expelled. The permeability enhancement shows that shallow aquifers can be significantly deformed for several days by moderate magnitude earthquakes.
