Two shallow-focus seismic tremors were recorded within approximately 1.5 hours at a relatively close distance in the northern suburbs of Attica.

The first tremor, with a magnitude of 2.6 on the Richter scale, occurred in the area of Chalandri shortly before 3:30 AM and was felt in several parts of Attica (reports from Agia Paraskevi, Cholargos, Papagou, Zografou, Psychiko, Patissia, etc.). According to the revised solution from the Geodynamic Institute, the epicenter was two kilometers southwest of Chalandri, with a focal depth of 5.7 kilometers, an area known for frequent tremors in recent times.

Notably, even earlier today, in the evening just before 10:00 PM, another much weaker tremor of magnitude 0.8 on the Richter scale was recorded near the same location.

The Euro-Mediterranean Institute reported the tremor at a magnitude of 3 and a focal depth of 6 kilometers.

The second seismic tremor, with a magnitude of 1.9 on the Richter scale, had its epicenter three kilometers south-southwest of Chalandri, with the focal depth measured at 7.9 kilometers, according to the Geodynamic Institute.

The Euro-Mediterranean Institute reported this tremor at a magnitude of 2.2 on the Richter scale, with a focal depth of 5 kilometers.
