We detected clear post-seismic signals of the Darfield earthquake, and a pre-seismic signal spatially and temporally associated to the Christchurch earthquake. The small pre-seismic signal (25 mm) has an opposite polarity of the much larger co-seismic one (150 mm) in the same area.COSMO-SkyMedChristchurch earthquakesDarfield earthquakesEarth crustEarthquakesInSAR monitoringInterferometryMonitoringNew ZealandSAR interferometrySAR-based techniquesSatellitesSeismic measurementsStressSynthetic aperture radarco-seismic polaritycrustal deformationearthquake anomalyearthquake triggeringpre-seismic signalremote sensing by radarseismic sequenceconference paper10.1109/IGARSS.2012.635065454dcce108580fe1368eeb5adhttp://ieeexplore.ieee.org/lpdocs/epic03/wrapper.htm?arnumber=635065454dcce108580fe1368eeb5ad
