Tsunami hits Japan after strong quake near Fukushima disaster site

A powerful earthquake rocked northern Japan early on Nov. 22, briefly disrupting cooling functions at a nuclear plant and generating a small tsunami that hit the same Fukushima region devastated by a 2011 quake, tsunami and nuclear disaster, Reuters reported. 
The magnitude 7.4 earthquake, which was felt in Tokyo, sent thousands of residents fleeing for higher ground as dawn broke along the northeastern coast.

"We saw high waves but nothing that went over the tidal barriers," a man in the city of Iwaki told NTV television network. 

Aerial footage showed tsunami waves flowing up rivers in some areas, and some fishing boats were overturned in the port of Higashi-Matsushima before the JMA lifted its warnings. 

The U.S. Geological Survey measured the Nov. 22 quake at magnitude 6.9, down from an initial 7.3. 

The cooling system for a storage pool for spent nuclear fuel at the reactor at its Fukushima Daini Plant was initially halted on Nov. 22, said a spokeswoman for Tokyo Electric Power, known as Tepco, but was restarted soon after. 

Only two reactors are operating in Japan, both in the...
