The population perceived the quake as a weak to distinct tremor and rumbling. Slight movement of liquids in glasses and shaking of screens were observed. The epicentral intensity reached grade 3 to 4 on the 12-degree European Macroseismic Scale (EMS-98).

• Degree 4 Largely observed: The earthquake is felt indoors by many and felt outdoors only by very few. A few people are awakened, the vibration is moderate, slight trembling of the building or room. Glasses, windows and doors rattle, light furniture shakes visibly.
