According to preliminary data, the earthquake was located at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deep ones because they are closer to the surface. The exact magnitude, epicenter and depth of the quake could be revised in the coming hours or minutes, as seismologists review the data and refine their calculations, or when other agencies release their report.
Cities near the epicenter where the quake could have been felt as very weak tremors include Pundong (population 24,100) located 116 km from the epicenter.
VolcanoDiscovery will automatically update the magnitude and depth if these change and follow up if other significant earthquake news becomes available.
