On the earth, earthquakes are no strangers to us. Earthquakes of different sizes occur almost every day around the world. On March 25, another major earthquake occurred around the world, and the tsunami warning has sounded. According to data from China Earthquake Monitoring Network, at 10:49 Beijing time, a magnitude 7.5 earthquake occurred in the Kuril Islands, with a depth of 30 kilometers. According to the European Mediterranean Earthquake Center, Hawaii, the United States has issued a tsunami warning. So, with the attention of friends near the earthquake, this earthquake may have a certain impact. The US Geological Survey also showed that it was a magnitude 7.5 earthquake, and the data was not very different (the data from the Tsunami Warning Center showed magnitude 7.7).
According to the data from the earthquake monitoring network, this magnitude 7.5 earthquake is also the fifth earthquake with a magnitude 6 (including magnitude 6 or above) since March. It is also the second major earthquake since this year (2020), with the strongest being the magnitude 7.7 earthquake that occurred in the southern waters of Cuba on January 29.
In the earthquake data, we can also see that a magnitude 7 earthquake occurred in the Kuril Islands on February 13, so the area is the second major earthquake since 2020 (the same area). This may also indicate that the major earthquakes in the region have been slightly active this year. It was only about a month, but I didn’t expect another major earthquake. After this earthquake, there have been three major earthquakes of magnitude 7 or above (including magnitude 7) in the world this year
According to China earthquake monitoring My data shows that this earthquake has caused the number of earthquakes of magnitude 6 (including magnitude 6 or above) to 20 times since 2020, so there are still many. Of course, this earthquake has issued a tsunami warning, indicating that the impact exists, and I will continue to observe the changes. Overall, the intensity of the earthquake is not low. From the perspective of location, the central area of the earthquake is located in the Pacific Rim earthquake zone, so this is also a normal earthquake. After all, major earthquakes occur almost every year in the Pacific Rim earthquake zone, so it does not mean that our earth is active or unstable again.
Earthquakes occur almost every day, and major earthquakes are relatively rare, but as long as the earthquake occurs, it may have a certain impact. Therefore, everyone should always pay attention to the development of tsunami warning or aftershocks. Earthquakes usually occur due to plate movement. According to data from the U.S. Geological Survey, on March 25, 2020, a magnitude 7.5 earthquake occurred east of the Kuril Islands. It was caused by a shallow "reverse fault" in the Pacific plate directly adjacent to (or below) the Kuril Islands. The Pacific plate subduction under the Okhotsk microplate, so this is how it was formed. Of course, this is also the most common earthquake explanation, and it is indeed the most common situation in natural earthquakes.
In addition to this natural earthquake, there is a relatively few earthquakes around the world, that is, artificial earthquake . This earthquake pattern is mainly because people are prone to trigger in recent mining, such as oil mining, etc., but the same sentence is still relatively few. This earthquake is relatively damaged to geological conditions, so it causes an unstable geological structure, which slowly triggers earthquake factors. Of course, the intensity of artificial earthquakes is not large, so the impact will not be too large. At the same time, scientists are constantly studying how to avoid earthquakes. Therefore, even if mining is required in the future, earthquakes in this aspect may occur much less.
earthquakes cannot be predicted in science. This is not the first time that it has been explained. However, in order to reduce the impact of earthquakes, scientists have developed the mechanism of "earthquake warning". Earthquake warning refers to sending an alarm to the fortified area a few seconds to dozens of seconds in advance to reduce local losses after the earthquake occurs. So it is very helpful. Now the world is constantly increasing the earthquake warning time to maximize the reduction of the impact of earthquakes. That is, we are gradually moving towards the era of "second warning". We are still looking forward to it. This is a situation of earthquakes.
