Migration of activity within normal fault systems: examples from the Quaternary of mainland Greece

摘要: Abstract We examine five areas of mainland Greece where active extension occurs on sub-parallel systems normal faults, and geomorphological stratigraphic evidence indicates that the faulting has migrated basinwards into original hanging walls, in several cases within late Quaternary. By comparing fault slip rates estimated from data with current known geodetic measurements, it appears newest faults can account for effectively all present-day motions. Fault migration this sort is easy to recognize young close sea level, because vertical movements footwalls walls are obvious reveal which currently most active, but less confirm away reliable reference levels or older terrains poorer time resolution.
