A 6.6-magnitude earthquake hit the Aegean Sea on Friday afternoon, jolting western Turkey and destroying buildings in coastal cities there. The Disaster and Emergency Management Authority (AFAD) said the quake occurred at 14.51 local time (1151GMT) at a depth of 16.54 kilometers (around 10 miles). People in the Turkish city of Izmir have gathered in the streets after fleeing their buildings to seek safety. The Disaster and Emergency Management stated that four people are confirmed dead with approximately 120 people injured so far. At least 20 buildings were destroyed in Izmir, the city's mayor Tunç Soyer told. Other western Turkish provinces, including Usak, Denizli, Manisa, Balikesir, Aydin and Mugla saw small damages to some buildings, he said. Turkish search-and-rescue teams continue their work on the field, the minister added. Istanbul Governor Ali Yerlikaya said the quake was also felt in Istanbul, but no negativities were reported. Turkish President Recep Tayyip Erdoğan said that Turkey stands by the citizens affected by the earthquake.” “We took action to start the necessary work in the region with all our relevant institutions and ministers,” Erdoğan added. “Our 38 ambulances, 35 UMKE team and 2 ambulance helicopters are at the scene. We stand by the people of Izmir with all our support.” Turkish health minister Fahrettin Koca said. The environment and urban planning minister, Murat Kurum, said people were trapped under the wreckage and rescue efforts were underway. The quake was felt across the eastern Greek islands and even in the Greek capital Athens. Greek media said the residents of Samos and other islands fled their homes, while some rockfalls were reported. The National Observatory of Athens Geodynamic Institute initially put the magnitude of the quake at 6.6 but later revised it to 6.7. The United States Geological Survey put the magnitude at 7.0. It is common for preliminary magnitudes to differ in the early hours and days after a quake. https://youtu.be/V5H2dyNbfog https://youtu.be/v8NM4j1QcEo https://youtu.be/0A2idN8KUpg In January more than 30 people were killed and more than 1,600 injured when an earthquake struck Sivrice in Turkey's eastern Elazig province.
