'Scary': Videos Show Japan Earthquake That Killed Four, Injured Dozens

Videos show a 7.4 magnitude earthquake hitting Japan, which killed at least four people, injured dozens more and left millions without power.

The earthquake hit off the coast of Fukushima prefecture at 11:36 p.m. local time on Wednesday at a depth of 57km, according to the Japan Meteorological Agency. It struck two minutes after a smaller 6.1 magnitude quake.

A tsunami warning, which has since been lifted, was triggered for the Miyagi and Fukushima prefectures, amid fears the country would witness devastation similar to that following a 9.1 magnitude earthquake in 2011. That earthquake, the biggest the country has experienced and the third largest in the world since 1990, triggered a tsunami and sparked a nuclear accident at Fukushima Daiichi nuclear plant. Over 18,000 people died.

Prime Minister Fumio Kishida told a parliamentary session on Thursday that four people had died and a further 97 were injured following the earthquake. He said the deaths were being investigated.

Power Outage

About 2.1 million people were without electricity by midnight on Wednesday after the initial earthquake caused power generation equipment to shut down, according to Tokyo Electric Power Company Holding, the country's largest electricity provider. By 2:52 a.m. on Thursday power had been restored to all households, it said.

The company is in charge of the Fukushima Daiichi nuclear plant and said on Wednesday that it was running as normal.

The tremors were felt outside of Fukushima, in areas including Miyagi and Tokyo. Videos of the impact soon emerged online.

One video from Koriyama, a city in Fukushima, showed an apartment violently shaking, with glass appearing to smash in the background. The caption on the Twitter post read: "The earthquake was big" alongside a shocked face emoji.

Another taken in a 10th-floor apartment in Tokyo's Heiwadai residential area showed an ornamental bell ringing as the building shook.

Twitter user @sheslovelie wrote alongside the video: "Was really scared. Hope everybody is safe."

John Daub, a YouTuber known for his ONLY in JAPAN channel, was in Tokyo at the time and shared footage of items including computer monitors and plants trembling.

"Strong M7.3 earthquake rocking Fukushima, this is my desk in Tokyo now—you can hear the whole apartment building shaking. Scary," he wrote.

He later tweeted: "Bad memories of March 11, 2011 for us but we're fine in Tokyo."

Instagram user morino_medaka, a killfish breeder in Miyagi, shared footage of what appeared to be water tanks being shaken.

The caption read, according to Google translate: "Thank you everyone for your concern. I couldn't stand this shaking! The indoor gallery is collapsing, just waiting for tomorrow. Life is safe. It was a ridiculous shake." Morino_medaka later shared photos of collapsed shelves.
