Ground Report

Per the USGS, a 5.9-magnitude earthquake struck Saturday afternoon near Honshu, Japan, and it was felt in Tokyo just 110 kilometers (70 miles) away.

It is not yet clear if the quake was an aftershock of a 6.3 quake that shook Northern Japan on Friday.

@nevaneva of Chiba, Japan, had the first tweet on the earthquake.
