A huge earthquake measuring 7.8 in magnitude has struck off the coast of Japan, according to the United States Geological Survey (USGS).
The quake struck off Japan’s Bonin Islands but tremors were felt around the country including in Tokyo.
CNN’s Tokyo correspondent Will Ripley tweeted: “Strong #earthquake right now in #Tokyo. Earthquake alarms going off at the gym.”
He added that there were no immediate signs of structural damage from the quake.
That quake was DEEP and powerful at 590km. No Tsunami but nearly everyone in Japan got a taste of it. pic.twitter.com/F1mZhIrcw2— Robert Speta (@robertspeta) May 30, 2015
It is thought that because the quake was so deep, the aftermath may be limited.
A tsunami warning has not been issued.
There were no reports of any casualties.
Both runways at Tokyo’s Narita airport were closed while inspections took place in the aftermath of the tremors, and railways were also examined, according to AFP.
We had a very strong earthquake here in Japan and I hope everyone is ok. Please use caution.— Johnny Weir (@JohnnyGWeir) May 30, 2015
Just felt the entire building sway from the 8.5 magnitude earthquake - 51st floor of the Ritz in Tokyo. Bracing for aftershocks— Silvanus Lee (@dreamspiel) May 30, 2015
