Short summary
Instruments buried across an earth-fissure zone in Chino, California since 2011 show opening during pumping and closing during recovery of about 30% of the lowest estimate of the threshold for major fissure opening. Continuous measurements of horizontal strain, water-level fluctuations, and subsidence can provide a real-time management tool to restrict pumping if strain approaches the lower limit of strain-at-failure or a stress-strain curve deviates from the previous mostly elastic regimen.
