文摘

The Gulf of Corinth, Greece, is a 110-km-long by 30-km-wide active graben displaying strong seismicity hosted both on north and south dipping normal faults. This complex fault pattern consists of two fault populations, offshore and onshore. The offshore fault population is investigated by densely arranged seismic reflection profiles during the last 20 years, whereas the onshore fault population displays spectacular and well exposed faults, delineated by high accuracy mapping. We analyzed fault length and throw, in order to study the scaling properties of 136 well-determined offshore and onshore faults and the comparison between the two datasets. We examined the statistical properties on both fault populations, in order to describe the role of segmentation in the growth of faults and the different stages of the evolution of the fault networks.
