Crustal stress and seismic activity in the Ionian archipelago as inferred by satellite-and ground-based observations, Kefallinìa, Greece (original) (raw)

2006, Geological Society, …

Different observational techniques are compared in order to investigate possible correlations in seismic activity. The study site is the island of Kefallinìa (Greece), where measurements available included (1) DInSAR, DGPS, and DEM data, (2) soil exhalation measured by monitoring Radon (Rn) well content, and (3) acoustic emissions (AE) at high and low frequency (point-like records with high temporal resolution). AE records provide: (1) relative time variation of the applied stress intensity and (2) the state of fatigue of stressed rock volumes, the AE source.
