| Zusammenfassung |
| The Public Power Corporation (PPC) of Greece has established four dammed reservoirs,
downstream of each other on Aliakmonas River in North Western Greece (namely the
artificial lakes of Ilarionas, Polyphyto, Sfikia and Asomata). In addition to the monitoring of
the reservoir water levels the PPC has also installed a dense seismological network
in the wider area. In this investigation the correlation between the local seismic
activity and the water level fluctuations at the Ilarionas and Polyphyto reservoirs is
studied.
On October 25th, 1984, during the Asomata reservoir initial filling, a Ms=5.4 earthquake
occurred in the region which was characterized by weak seismicity, until the strong
earthquake of Ms=6.5 that occurred on May 13th, 1995, at a distance of 18 km from the
southern edge of the Polyphyto reservoir. More recently, on July 2nd and 3rd, 2013, two
moderate earthquakes (Ml=4.7 and Ml=4.6) occurred, almost a year after the filling of the
Ilarionas reservoir in 2012. In addition to these events, fourteen earthquakes with magnitudes
equal or greater to Ml=4 have also been detected in the wider area of the Aliakmonas
reservoir. |
