Japan tsunami warning as 7.3 tremor hits Fukushima and rocks Tokyo

A huge 7.3-magnitude earthquake has hit Fukushima, Japan, prompting a tsunami warning. Tremors were felt as far away as Tokyo, which is almost 150 miles away from Fukushima.

Parts of Tokyo have endured power outages as a result. It is not yet clear if any people were injured following the quake, or the scale of damage caused.

Reports suggest there were two earthquakes, with the second having more impact and lasting for two minutes. The quake was reported just after 11.30pm local time.

British YouTuber Chris Broad in Sendai, a city just more than 40 miles northeast of Fukushima. He said it was the 'scariest earthquake' he had experienced in 10 years.

In a Tweet, he added: "Had an actual panic attack & thought the whole bloody building was coming down. Started with a big one that died off.

"Then all of a sudden a 2nd massive one that knocked half the apartment over. Fire alarms going off all around Sendai right now."

He went on to share a map of the seismic activity, adding: "For some reference I was inside the red dot. Genuinely astonished that none of the buildings came down. Thank you engineering. You’ve won."

James Reynolds, who describes himself as a British global tropical cyclone interceptor, also lives in Japan. He tweeted: "All safe here - waiting for more information. Looks like powerful earthquake offshore Tohoko Japan. A few things knocked off shelves etc, internet messed up in Tokyo, no doubt much worse further north."

He also claimed the warning system did not provide any warning of the earthquake beforehand.
