Japan is a country with many volcanoes and earthquakes, and large-scale earthquakes often occur. According to Japanese media reports, on February 15th, a large number of dead fish appeared on the beach of Span1span Miyake Island in Japan, as many as tens of thousands, stretching for more than 600 meters. The cause of their death is unknown. People have speculated that it may be related to the earthquake.
At 23:07 on February 13 this year, , Japan’s Honshu , was damaged by a 7.3-magnitude earthquake in the eastern part of the island. More than a hundred people were injured. An earthquake is a violent geological activity that can release a large amount of , radon, methane and other gases into the water instantly, causing hypoxia in the sea water or poisoning of the fish, and sometimes the earthquake will produce loud noises, and high-decibel sound waves propagate in the water , Will also shake the fish to death, so if a strong earthquake occurs in the ocean, it may cause the fish to die.
However, this earthquake is almost certainly not related to the dead fish incident mentioned above, because the distance between the two is too far, Miyake Island and the epicenter of the February 13 earthquake The distance of the location is about 600 kilometers. It is certain that the two events are not related. If there is a direct relationship, then the entire beach on the east coast of Honshu, Japan should be full of dead fish.
However, at around 21:26 on February 15th, another earthquake occurred in the sea near Fukushima, Japan, with a magnitude of 5.3, but the earthquake was also far away from Miyake Island. It's very far, about 500 kilometers, so it doesn't matter.
Many people also speculated whether it was the Fukushima nuclear power plant ’s waste water leakage that caused the death of the fish.The Great East Japan Earthquake with a magnitude of 9.0 on March 11, 2011 caused severe damage to the Fukushima Nuclear Power Plant, causing a large number of nuclear leaks incidents. The Fukushima Nuclear Power Plant was therefore abandoned in order to reduce its internal The temperature can only be cooled with water continuously. Therefore, a large amount of waste water that has undergone nuclear radiation is also produced. At first, a lot of waste water leaked into the sea. Later, the nuclear waste water was stored in large tanks, but Japan has decided Wastewater that is nowhere to be placed will be dumped into the sea. Was this dead fish incident caused by the dumping of nuclear waste water by Japan?
In fact, this possibility is almost impossible, and the reasons mentioned above are almost the same, because the Fukushima Nuclear Power Plant is also very far away from Miyake Island, and the linear distance exceeds 500 kilometers. Since the Fukushima Nuclear Power Plant is near No dead fish appeared yet, so the dead fish that appeared thousands of miles away had nothing to do with it.
Some geologists also inferred that it may be related to certain geological activity anomalies near the Japanese Nanhai Trench . For example, on the eve of a large-scale earthquake, frequent crustal activities will stimulate radon and methane Waiting for the release of gas, the nearby seawater is short of oxygen, causing the death of fish, so this phenomenon is likely to herald the appearance of a strong earthquake.
For example, " king hairtail ", which is called "seismic fish", often appears on the sea on the eve of an earthquake, which is also caused by this reason. Therefore, the appearance of seismic fish is often considered an earthquake The precursor to the occurrence. However, this is still a more likely guess. The cause of the death of fish on Miyake Island in Japan needs further analysis and research.
