People likely experienced very weak shaking there. Many smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking.

Greece7.1 km (4.4 mi) epicenter difference with NOAAUTH (Aristotle University of Thessaloniki Geophysical Lab.)Earthquake statisticsAverage number of earthquakesBased on data from the past 26 years and our earthquake archive back to 1900, there are about 922 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.1 quakes per year (or 1 quake every 10.5 years)Mag. 5 or higher: 1.24 quakes per yearMag. 4 or higher: 18.2 quakes per yearMag. 3 or higher: 175 quakes per year (or 14.6 quakes per month)Mag. 2 or higher: 778 quakes per year (or 65 quakes per month)Mag. 1 or higher: 921 quakes per year (or 77 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 12 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 10 to 15 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
