Greece: A magnitude-5.3 offshore earthquake occurs in Aegean Sea at around 19:03 Nov. 3

A magnitude-5.3 earthquake occurred near northeastern Greece at around 19:03 Nov. 3. The epicenter was approximately 8 km (5 miles) south-southwest of Nea Poteidaia. The tremor occurred at a depth of about 10 km (6 miles), and weak-to-moderate shaking was probably felt throughout much of Greece and some surrounding regions. There have been no initial reports of damage or casualties as a result of the earthquake; significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Aftershocks are likely over the coming days. The event has not prompted any tsunami advisories.

Officials may temporarily shut down transportation infrastructure in the tremor zone to check for damage. Minor disruptions could occur during shutdowns, but service will likely resume quickly if no damage is found. Utility outages are possible, particularly near the earthquake's epicenter.
