The core of this incident is the large-scale death of anchovies discovered on the southern white sand beach of Gyeongpo Beach in Gangneung in the early morning of the 10th. A large amount of anchovies were washed up by the waves, forming a band spanning over 100 meters, and some were even seen fluttering on the white sand beach while still retaining their vitality. Since this was the first large-scale exodus to occur this year, interest from local residents and tourists was even more intense. In the past, there were similar cases along the east coast, including Gangneung, Yangyang, and Goseong, and each time, a unique scene unfolded where residents would bring out scoops or bandu to pick up anchovies. This incident also stimulated the curiosity of many people and made the morning at Gyeongpo Beach noisy.

Experts agree that this phenomenon is a natural ecological activity that repeats every summer on the East Coast. The most likely hypothesis is that schools of anchovies, chased by top predators such as mackerel and herring, desperately tried to escape, lost their sense of direction, and ended up in shallow coastal waters. In fact, the catch of herring has recently increased rapidly along the east coast, so it is very likely that this predation pressure has encouraged the influx of anchovy schools to the coast. In addition, the analysis that the cold water phenomenon, which causes rapid changes in water temperature, may have also affected the migration routes and biological rhythms of fish is gaining persuasiveness. In other words, it is reasonable to view the mass death of anchovies as a result of intense food chain relationships within the marine ecosystem rather than a precursor to a disaster such as an earthquake.

Nevertheless, the reason why public anxiety does not go away easily is because of the earthquake in the Ulsan area that occurred early that same day. As a magnitude 2.9 earthquake was observed in the waters 24km northeast of Buk-gu, Ulsan at around 3:16 a.m., people are expressing concern that the abnormal behavior of anchovy schools may be related to tectonic shifts. In fact, the myth that deep-sea fish rise to the sea level or that the ecosystem is disturbed before a major earthquake is a powerful factor in stimulating public fear. However, the scientific community is resolute in saying that there is no evidence to prove a direct correlation between the anchovy phenomenon and the earthquake. We believe that making unreasonable connections between geological events such as earthquakes and changes in fish behavior is nothing more than vague speculation that lacks scientific basis.

In the end, the commotion over the anchovies on Gyeongpo Beach clearly shows the asymmetry of information faced by modern society and the resulting psychological reaction. It may be a natural human defense mechanism for local residents to think of an earthquake when they see a school of anchovies while walking barefoot. However, rather than blindly trusting fragmented information, we must maintain an attitude of looking at the phenomenon objectively based on expert analysis and scientific verification. Rather than spreading unnecessary social fear by misinterpreting the natural ecological cycle of the East Coast as a sign of disaster, more efforts are needed to observe and understand the changing marine environment. This incident served as an opportunity to once again remind us of the importance of having a correct perspective on nature and making accurate informed decisions.
