Overview

• The epicenter was located at sea about 45 kilometers northeast of Athens and roughly 4 kilometers off Nea Stira.
• The tremor was strongly felt in the capital, according to initial reports.
• Marathon mayor Stergios Tsirkas told public broadcaster ERT the quake felt very intense, with no damage reported so far.
• The jolt follows an intense January–February swarm around Santorini that produced thousands of small quakes and temporary evacuations.
• A magnitude 6.1 event off Crete in May shook a wide region, underscoring Greece’s exposure to frequent quakes along multiple faults, including the deadly 2020 Samos shock.
