Watch: Tsunami Hits Japan After Magnitude 7.4 Earthquake

On Tuesday, when a magnitude 7.4 quake hit Japan’s northeastern coast, the country began immediate evacuation.

Tsunami waves were witnessed in Japan’s Sunaoshi River after an earthquake of 7.4 magnitude hit the little island country on 22 November. Waves were also seen crashing into beaches.

Tsunami warnings were issued following the earthquake and coastal residents were evacuated well before the waves hit.

A 60 cm (2 foot) tsunami was observed at Fukushima's Onahama Port and a 90 cm (3 foot) tsunami at Soma soon after, public broadcaster NHK said.

Speaking in Argentina, Japanese Prime Minister Shinzo Abe said the government will do its utmost to respond to the earthquake.

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