Weishan weather forecast

The northeast volcano has been sleeping for 500 thousand years. Why is it ready to move now?

Living on the earth, human beings can not only enjoy the magnificent beauty of nature, but also face some unknown disasters. The earth we live in has existed for 4.6 billion years, and many natural disasters have occurred in the evolution of the earth. Serious disasters even lead to biological extinction, such as great oxidation events and volcanic eruptions. These natural disasters are beyond human control. There are volcanoes all over the world. Friends who have seen the movie 20 12 may know that there is a super Yellowstone volcano in the United States. The last large-scale eruption of this volcano was 640 thousand years ago. Although the super volcano has not erupted so far, the geological activities around Yellowstone National Park in the United States are indeed very active today. The US Geological Survey tracked the 107 earthquake in only one month. This has further aggravated people's concerns about volcanic eruption. In the eyes of ordinary people, this active geological activity may mean that this super volcano may have woken up from a deep sleep.

Because in a short period of one month, the US Geological Survey not only monitored 107 earthquakes in Yellowstone National Park, but also the strongest earthquake reached 3. 1, which indicated that the geological movement at the bottom of the volcano was under way. In addition to seismic activity, the US Geological Survey also investigated three large eruptions in nearby geysers, with boiling pool water spewing hot jets. Fortunately, after further investigation by USGS, the conclusion is that the seismic activity in Huangshi National Park is still at the background level, that is to say, the seismic activity near Huangshi National Park is still within the normal range, and the earthquakes near Huangshi National Park are almost brittle failure events caused by crustal stress, which does not mean that Huangshi volcano is preparing to erupt.

After learning about Yellowstone Volcano, let's learn about a volcano in China that is a little eager to move. During the investigation, scientists found a volcano named Weishan in Wudalianchi area. They found two huge magma sacs at the bottom of the volcano. According to the data, the melting degree of these magma has reached 15%. If it continues to expand, reaching more than 40% may trigger a volcanic eruption. Of course, after careful exploration and research, scientists said that there is no need to worry too much about this situation, because it takes a long time for magma to melt, and this time span may reach 654.38+ million years. Therefore, it can be judged that this volcano will not cause a big explosion in a short time.

According to scientists' calculations, it has been 500,000 years since the last eruption of this volcano. Because this volcano has not erupted for a long time, most people take it for granted that it is an extinct volcano. If scientists hadn't discovered this volcano by accident, many people wouldn't even know it existed. Volcanic eruption can be said to be a very serious natural disaster, and human beings can predict the time of earthquake in advance through science and technology in order to leave enough time to escape.

That is to say, although natural disasters are inevitable, we humans can make predictions after exploring and studying in advance, thus further increasing the escape time to avoid natural disasters. This can be seen from the human weather forecast. With the continuous development of science and technology, the accuracy of current human weather forecast is becoming more and more accurate. When encountering droughts, floods and typhoons, we can basically make predictions in advance, which greatly reduces the losses caused by natural disasters. Although scientists predict that Weishan volcano will not erupt in a short time, we should pay close attention to the volcano's every move in order to prevent it in advance.
