Magnitude 7.3 #earthquake off the coast of Fukushima Prefecture, Japan at 1:10pm EDT US time. Felt from Tokyo to northern Japan.

Japanese authorities have issued a tsunami advisory for Fukushima Prefecture, expecting a 1-meter (3-foot) tsunami by 1:40pm EDT US time.

Just a coincidence? This is from earlier this week:

IS THE discovery of rare "sea serpents" off the coast of California at the weekend a sign of an impending disaster?

Carcasses of two of the sea snake-like creatures, of 5.5m and 4.2m in length respectively, were discovered washed up along the state's coast last week.

According to Japanese folklore the so-called 'monsters of the deep' rise to the surface of the ocean and beach themselves to warn of a coming earthquake, CBS Los Angeles reports.

In the months before the Fukushima earthquake disaster, over a dozen slender oarfish washed ashore or were caught by fisherman on the country's northern coast near the quake's epicentre.

"Japan is bracing itself after dozens of rare giant oarfish - traditionally the harbinger of a powerful earthquake - have been washed ashore or caught in fisherman's nets," the UK's Daily Telegraph reported at the time.

[...] Scientists, however, disagree with the ancient fable and say there is no scientific relationship between sightings and seismic activity.

"It's probably just a coincidence," Rick Feeney, a zoologist at the US Natural History museum said.
