Japan was yet again rattled by a 7.4 magnitude earthquake, Thursday night. A tsunami warning was immediately announced after the quake was felt.

Broadcasters of Japan’s public news network told people living in the northeastern shore of the country to evacuate to higher grounds and as far away from the shore as possible. One hour after the quake hit Japan, no tsunami was observed hitting the shore.

Officials of Fukushima Dai-ichi nuclear plant (a nuclear plant that is still managing the damages caused by the previous tsunami that hit Japan barely a month ago) said that they see no immediate signs of additional problems from the recent quake. No one in the plant was injured as the workers were immediately relocated to a quake-resistant area inside the complex.

Government officials said that the aftershock hit 50 kilometers off the coast of Miyagi prefecture. Buildings in Tokyo shook for as long as a minute. In Ichinoseki, a place closer to the Miyagi prefecture compared to Tokyo, shelves and furniture were knocked out. Right after the quake, electrical supply to that area was cut to prevent accidental fires.

The earthquake shook Japan at 11:32 in the evening, local time. A little earlier than that, Japanese TV already announced a warning for a possible quake and loudspeakers warned residents of the western suburbs in Tokyo.

Experts are not expecting an ocean-wide tsunami but they emphasized that quakes that strong may cause local waves that can cause vast damages.
