A powerful earthquake hit Greece and Turkey causing buildings to collapse and a sea surge that flooded streets in the Turkish resort city of Izmir. Greek public television said the quake also caused a mini-tsunami on the eastern Aegean Sea island of Samos, damaging buildings.
Samos is host to one of the three major refugee camps on the Greek islands. The other two are on Chios, which is about 50 miles north of Samos and directly west of Izmir, and Lesbos, which is about 50 miles north of Chios.
