Since July, there have been relatively few earthquakes around the world, which is a very good thing. After all, the impact of a major earthquake can be said to be very large. According to data from China Earthquake Monitoring Network, the strongest earthquake in July occurred on July 14, located in the Hamahela Island area of Indonesia, followed by two earthquakes in the United States, one was magnitude 6.9 (the United States marked magnitude 7.1) and the other was magnitude 6.4. The overall data totals 8 times, which include earthquakes of magnitude 6 and above. Compared with June, the number of earthquakes is much less, and you may see that the earth has become much more stable.
Of course, for earthquakes, most earthquakes occur in fault zones or earthquake zones. Our earth has a "Pacific Rim Seismic Zone", and earthquakes of different sizes occur almost every day. So if you want to look at all the data, you can say that you will feel the earthquake data dozens of times a day, but most of them are not destructive, so don't worry. According to a July 25 scientific report by NASA (NASA), remote sensing scientists analyzed two major earthquakes in the United States and found some displacements.
We all know that during the two major earthquakes, there were no major casualties or infrastructure disruptions in the United States. The main reason, the scientific community has also announced that the earthquake occurred in a rare location, so this may be one of the reasons. However, two major earthquakes, one of which was the strongest earthquake in the region in at least 20 years, the ground underground in Southern California moved violently in early July 2019, which has been measured. After the earthquake, in a few days and weeks, thousands of aftershocks occurred in Southern California , most of which were too small to be felt by humans.
. Some scientific reports point out that stronger earthquakes may occur in the future, which has caused everyone's concern. According to the report of US Geological Survey , the occurrence of earthquakes has released energy in the area about 150 kilometers northeast of the San Andreas fault. The earthquake occurred within the "shear belt" (that is, the fault zone) in Eastern California. In this area, the fault and its connections are not as good as those of San Andreas, so the problem we are most worried about has not occurred. If there is a fault along the San Andreas fault, the problem may be quite serious.
How many times did the two major earthquakes move? According to the ARIA team, the land on the west side of the fault moved 0.8 meters (80 cm), and the red/orange area moved 0.6 meters (60 cm), so the displacement data caused by the two earthquakes is still relatively high. According to the U.S. Geological Survey, the Pacific plate usually moves northwest at a speed of about 48 mm per year (relative to the North American plate). This earthquake is an unexpected move. As for the same sentence, earthquakes are large, as long as they have no impact on humans, NASA provides this type of map to California Geological Survey to estimate where the fault moves deeper and which areas of stress increase, as well as the possibility of future earthquakes.
earthquakes cannot be predicted in science. This is not the first time I have said it, but there are still people who have "reverse" situations. I don't know why. For many earthquake clouds , earthquake fish, and biological abnormalities, there is no scientific basis for this for the time being. In other words, the scientific community has not admitted that these must be related to earthquakes. Therefore, everyone should believe in science. Earthquake warnings are widely used today, and they are constantly implementing "second-level warnings". This will also have more time to defend earthquakes. This is one of the best ways to defend earthquakes today.
