Recorded coordinates

The event origin is WND’s fixed reference point for this event; it is not revised when a provider updates its epicentre. Each provider reports its own current epicentre; a superseded location is kept as history. Distances below are measured from the origin.

Region and reference cities are derived by WND from the reported epicentre using Natural Earth 5.1.2 boundaries; they are not provider statements. Made with Natural Earth.
