A 3.6-magnitude earthquake struck earlier on Thursday off the coast of Mount Athos in the Halkidiki region, an autonomous monastic community and UNESCO World Heritage site located in central Macedonia.

According to the Geodynamic Institute, the epicenter was located 30 kilometers southeast of Karyes, the administrative center of Mount Athos, with a focal depth of 16.9 kilometers.

The earthquake comes two weeks after a larger 5.3-magnitude earthquake rocked the Mount Athos peninsula, which caused structural damage to several centuries-old monasteries in the region.

While no injuries were reported in that quake, concerns are mounting over the potential long-term impact on the region’s irreplaceable religious and cultural heritage.

Mount Athos is home to 20 Eastern Orthodox monasteries and numerous smaller hermitages. Access is heavily restricted and granted only to men, mainly pilgrims and clergy. It is widely regarded as one of the most spiritually and historically significant regions in Eastern Christianity.
