Formation Of New Faults Research Articles

The Gulf of Corinth: an active half graben?

The Gulf of Corinth is often considered as a typical example of a more or less simple half graben with major border faults to the south and a flexure of the northern shore. This paper reviews new data, especially subsurface data, from both onshore and offshore, compiled or acquired through the Corinth Rift Laboratory EEC project. This data indicate that (1) the Gulf of Corinth is bordered both north and south by active faults; (2) there is a lot of them, and not only the one bordering the Peloponnese coastline are still active; and (3) distinct opening phases may be recognized on the area. During the first phase, the depocenter was located near the northern shore, whereas during the most recent phase, and only in the centre and the eastern sector, the depocenter moved towards the southern shore. Furthermore, active tectonic, in this western sector, is characterised by a general uplift of the Peloponnese that leads to the formation of new faults, i.e. the Doumena, Aigion and Helike faults and to selective reactivation of older ones such as the Pirgaki fault. We suggest that this current tectonic phase started about 150–120 000 years ago in the Aigion area and about 350 000 years ago eastward (Corinth-city) and that it represents a third opening phase during the growth of the Gulf of Corinth.

This is especially true of faults that persist for long distances. The identification of active faults is of importance, since they are the loci of earthquakes, each new displacement of a growing fault resulting in an earthquake.Criteria used in recognizing active FaultsThe criteria that have been used in recognizing active faults are: (1) the recurrence of earthquakes along faults, and (2) physiographic and geologic evidence of recent displacement; but each of these may be misleading unless the general stability of the entire circumjacent region be taken into consideration.The Charleston earthquake of 1886 was one of the greatest recorded in North America, and aftershocks have continued in its epicentral area down to the . . .
