A little over four years ago, a week before the 2011 Tohoku earthquake and tsunami, 50 melon-headed whales were found beached in Ibaraki Prefecture, only about 100 kilometers (62 miles) from the earthquake’s epicenter.
Now the same omen of bad things to come has happened again. On April 9, about 150 melon-headed whales were found beached in Ibaraki Prefecture. As emergency teams race to save the whales, one thought is sitting in the back of their minds: is this foreshadowing another giant earthquake?
On April 9, more than 150 melon-headed whales (a type of dolphin) were found beached across a stretch of four kilometers (2.5 miles) of shoreline in Hokotashi City, Ibaraki Prefecture. Most of the whales were in critical condition, though the Ibaraki coast guard has been busy returning those still alive to the ocean. The ones that were too weak to be returned were euthanized.
The reason behind the mass beaching is still unknown, but it is suspected to be due to underwater tremors. Since melon-headed whales tend to prefer deeper waters, they would be more sensitive to plate/tectonic changes than other undersea mammals.
This has people worrying about another earthquake on the same or even higher level as the 2011 Tohoku earthquake and tsunami. There is a theory that beached whales are often a sign of undersea tremors, and the severity of the incoming earthquake can be estimated by how many whales are beached. The coast guard reported that while every year some amount of whales are found beached on the shoreline, this incident is by far the most that they have ever encountered.
The city where the beaching took place, Hokotashi City, has started to take emergency measures against the predicted earthquake and tsunami. It is unclear whether the surrounding areas are preparing as well, but they should seriously consider it. To all our readers in the area, be safe and stay alert for any warnings!
