Israelis across the country reported experiencing a minor earthquake on Saturday morning, less than two hours before an earthquake beneath the sea shook northern Greece and western Turkey, with more than two dozen injuries reported on a Turkish island.

The 4.1-magnitude earthquake hit Israel at 10:26 a.m., causing no damage but making houses shake, eyewitnesses said. Less than two hours later, just after midday, a stronger earthquake struck parts of Greece and Turkey, causing residents to flee their homes in panic.

The private Dogan news agency said the temblor caused damage to some old houses on the island of Gokceada, off Turkey’s northern Aegean coast, and 30 people were taken to a hospital with minor injuries.

The quake struck at 12:25 p.m. local (0925 GMT) southwest of the Greek island of Samothraki, 210 kilometers (130 miles) east of Thessaloniki and 296 kilometers (185 miles) northeast of the capital Athens. It was also close to the Turkish island of Gokceada and the Greek island of Lemnos.

A duty officer at the Lemnos police precinct said a female British tourist was slightly injured at the airport when part of the ceiling fell, but she was treated at the scene and did not require hospitalization. No other damage or injuries had been reported.

The Institute of Geophysics at the Aristotle University of Thessaloniki said the temblor announced a magnitude of 6.3; the U.S. Geological Survey initially reported a magnitude of 6.4, later revised to 6.9.
