- A strong earthquake measuring 6.7 on the moment magnitude scale hits Greece at 13:34. The earthquake's epicentre was in the sea region 25 km east of the island of Kythira, about 200 km south of Athens. Although it was felt as far as Sicily, south Italy, Egypt, and Amman in Jordan, it was not disastrous due to its deep hypocentre and the sea-bed epicentre. Little damage (mainly in Kythira) and few light injuries are reported. (CNN.com) (USGS)
