General information: magnitude measures the energy released at the source on a logarithmic scale — each whole number is roughly 32 times more energy. Depth is how far below the surface the rupture began. Whether an earthquake is felt, and how strongly, depends on many factors and is best shown by felt reports and intensity data.
The epicentre was located at 36.0809 latitude and 139.7782 longitude, 2 km SW of Sakai, Japan. The earthquake was intermediate-depth at 71.0 km depth.
