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 -3.1500 latitude and 139.4100 longitude, 69 km NE of Kobagma, Papuapgngn, Indonesia. The earthquake was intermediate-depth at 100.0 km depth.
