Recently, there has been a shocking news circulating on the Internet: in 2020, Japan's volcanic eruptions, groundwater pollution and other reasons have caused a large-scale odor phenomenon for a period of time. Does this mean that there will be a mega earthquake in 2021?
The first thing we need to understand is that the relationship between earthquakes and odors does not necessarily exist. Although both may occur at the same time in some cases, they cannot be used as a criterion for predicting earthquakes.
According to experts, this is mainly due to the many volcanic activities that took place in many parts of the country, especially Mt. Fuji in Fukushima Prefecture. These volcanic eruptions release large amounts of sulfur gases that mix with the surrounding air to form a strong pungent odor that we call "odors."
In addition, some areas have contaminated groundwater, which is also part of the cause of odors. Some pollutants such as industrial wastewater and agricultural fertilizers enter the groundwater, and after a long period of accumulation and reaction, they produce an unpleasant taste.
Although the causes of odors may seem complex, they are actually changes in the natural environment. This change does not directly cause an earthquake. Scientists generally believe that earthquakes are caused by crustal movements in the Earth's interior and require certain geological conditions to trigger.
Therefore, we should remain calm in the face of such news and not easily believe rumors. For future natural disasters, we should pay more attention to prevention and improve our ability to respond to disasters.
Overall, the odor phenomenon in Japan in 2020 was the result of a combination of factors, but it does not predict that a mega earthquake will occur this year. We should look at these problems rationally and take precautions and responses in a scientific manner.
