Maps of the Aigion and Helike faults at different scales

Mapping of the Aigion and Elike faults was completed on a 1:50000 and 1:5000 scale and the results are included as layers in the GIS-database. We have also attempted to develop a segmentation model for the area based on geometric complexity, extent of co-seismic ruptures, and geomorphic and geologic considerations.

Geometric and kinematic parameters for each fault as well as the maximum expected magnitude have been estimated on the basis of detailed field-work and empirical relations. Fault dip and rake were assumed according to field observations and geophysical information, whereas fault width was inferred on the basis of the instrumental seismicity distribution.

These results are of relevance for any investigation in the active tectonics and seismo-genesis in the area and they could contribute as primary input to deterministic seismic hazard evaluations.
