Since January 2020, we have encountered countless natural disasters and problems, including volcanic eruptions, storms and other disasters. At 14:31 Beijing time on January 26, another strong earthquake occurred around the world, that is, the magnitude 6.1 earthquake in Alaska, USA. The earthquake in this area can be said to be "super active". Although this earthquake was magnitude 6.1, it is not the first earthquake in the region within 24 hours. According to scientific statistics from the US Geological Survey website, the same area reached 11 times, and before a magnitude 6.1 earthquake occurred and 2 hours ago, a magnitude 5.7 earthquake occurred in the same area.
It can be imagined that this area is already in an earthquake zone that may be more active for a short period of time. This magnitude 6.1 strong earthquake did not trigger a tsunami warning, and it happened to be in a sparsely populated area, so the impact is not big for the time being.
China marked this earthquake as magnitude 5.9, please refer to the data differences. According to data from China Earthquake Monitoring Network, since January, we have recorded many strong earthquakes. Earthquakes above 6 (including magnitude 6) have reached 9 times. The strongest one is the magnitude 6.8 earthquake in Turkey on January 25, Beijing time, and the second is the magnitude 6.5 earthquake in the waters near Puerto Rico.
So judging from the data of strong earthquakes, there were still many in January. Turkey's magnitude 6.8 strong earthquake has still had a lot of impact, which has caused casualties. Therefore, with Turkish friends paying more attention, we should pay attention to the impact of aftershocks. This earthquake not only affected Turkey, but also had an impact on neighboring countries and regions, so we should pay attention.
According to scientific reports, Turkey is also in an earthquake-prone zone, and has experienced strong earthquakes in history, so this earthquake is a normal situation, but the impact is great, which is what everyone least wants to see. Data shows that in 1999, two consecutive earthquakes of magnitude 7 or above occurred in northwestern Türkiye, killing about 18,000 people. In 2011, a magnitude 7.2 earthquake occurred in a province in eastern Türkiye, killing 644 people. Therefore, these earthquakes have affected a wide range and affected many areas.
We all know that on the earth, there is a Pacific-ring earthquake zone, and earthquakes of different sizes occur almost every day in this area. One of the main factors for earthquakes may be the plate movement or fault zone sliding we are talking about. Almost every time a major earthquake occurs, it must be explained through this.
Of course, many people say that this may not be the case in which earthquakes occur. There are indeed, for example: artificial earthquake , but the magnitude of this earthquake occurs relatively few, which is much more intense than the earthquake induced by plate movement or fault zones, which is basically negligible. As long as it is not in the area of human destruction. As there are so many earthquakes, everyone should know that one of the issues we are most concerned about is that earthquakes cannot be predicted. Many times we see how high the probability of earthquakes occurring in a certain area is. In fact, that is just a basic explanation and does not have the possibility of accurately predicting earthquakes. For example: In the next 30 years, Japan estimates that a major earthquake may occur, which will kill tens of thousands of people and lose millions of people. And this is a basic explanation, and it does not necessarily happen, so it has nothing to do with earthquake prediction.
Earthquakes are unpredictable, earthquake warnings are done more in the scientific community, and earthquake warnings have helped us humans a lot. Earthquake warnings are mainly through the occurrence of earthquakes, and seismic waves propagate and then docked in artificial technology to "competition in time."That is, a warning before the earthquake waves propagate to the target damage area. This data can now be achieved dozens of seconds in advance, or even more than one minute. It is a major breakthrough made by our scientists in earthquakes. In the future, scientists will continue to conduct further research and will fully implement earthquake second-level warnings around the world, so the impact will be lower. So this is very good news. I hope we can effectively reduce the impact of earthquakes in the future. Let's look forward to it together.
