After the Athens-Rome agreement on the continental shelf signed two years ago, seismic surveys will begin in the marine "block 2" - Ionian Sea - to identify potential hydrocarbon targets.

Seismic activity in the wake of the 5.1-Richter tremor that rattled the Greek capital last Friday appears to point to a gradual release of pressure on the fault that produced the earthquake, an expert has said.

A team of seismologists from the Athens National Observatory's Geodynamic Institute has been dispatched to the areas of Ileia and Achaia in the Peloponnese following the succession of aftershocks that have followed a 4.9-magnitude quake off the coast of Katakolo on Monday.
