Numerous videos of the moment the powerful 7.4 magnitude earthquake that struck off the coast of Fukushima, Japan on Tuesday have been circulating around the internet. A clip uploaded by newspaper Guardian shows the suspended transit signs at a train station swaying back and forth the moment the tremor hits. Scientists believe the earthquake, which lasted for several second and was felt in Tokyo, was a delayed aftershock of the 2011 tremor that had rocked Fukushima.
