Greece: A magnitude-4.7 offshore earthquake occurs off the west coast of the Peloponnese Region Jan. 6

A magnitude-4.7 earthquake occurred in the Gulf of Kyparissia off the west coast of the Peloponnese Peninsula at around 11:47 Jan. 6. The epicenter was about 97 km (60 miles) south of Patras. The tremor occurred at a depth of about 5 km (3 miles), and light shaking was probably felt in areas close to the epicenter, as well as weak shaking throughout parts of southern and south-central mainland Greece. There have been no initial reports of damage or casualties as a result of the earthquake, and significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Light 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.
