A powerful earthquake has struck off Turkey’s Aegean coast and north of the Greek island of Samos, destroying a number of houses. The 7.0 magnitude tremor was centred off Turkey’s Izmir province, the US Geological Survey (USGS) said.  Turkey put the magnitude lower, at 6.6, saying 12 people had died and 419 were injured in the city of Izmir. On Samos, two teenagers were killed. The shallow tremor triggered a mini-tsunami that flooded Izmir and Samos. The USGS said the quake – which was felt as far away as Athens and Istanbul – struck at a depth of 10km (six miles), although Turkish officials said it was 16km below ground. Turkey and Greece both sit on fault lines and earthquakes are common.In Izmir, Turkey’s third largest city with the population of nearly three million, many people were seen running out into the streets in panic and fear after the quake struck. At least 20 buildings collapsed.(BBC)…[+]
