An earthquake occurred in Crete, which has caused a tsunami warning to be issued. Here's what it means if you're in the Crete and Greece areas.

A strong, 6.0-magnitude earthquake struck in the Mediterranean Sea on Wednesday, according to the United States Geological Survey. The temblor happened at 1:51 a.m. Eastern European time about 14 miles southeast of Fry, Greece, data from the agency shows. U.S.G.S. data earlier reported that the magnitude was 6.1.

Authorities issued a tsunami alert in the area shortly after the tremor, which was felt as far away as Israel, Syria and Egypt. View on euronews
