A strong undersea quake measuring 5.6 on the Richter scale was recorded yesterday morning in the northeast Aegean, off the isle of Psara and close to Chios, but there were no injuries or damage reported. The quake, whose epicenter was about 20 kilometers from both Chios and Psara, was felt as far away as Athens. It occurred shortly before 4 a.m. yesterday and was followed by two aftershocks, measuring 5 and 5.3 Richter respectively, just after 9 a.m. Seismologists said they were monitoring the area.
