A tsunami warning has been issued for part of Japan following a strong earthquake.
The 6.9 magnitude earthquake struck eastern Japan around 6 a.m. local time Tuesday.
The Japan Meteorological Agency observed a tsunami wave about 13.6 miles off the coast of a city in the southeastern part of the Fukushima region.
Fukushima may sound familiar to you. In 2011, an earthquake and subsequent tsunami contributed to a nuclear accident at a power plant in the northeastern part of the region.
