In science, human science and technology currently cannot accurately obtain earthquake predictions and can only be judged through data and measurements. According to researchers from the American Geological Society, San Andreas fault may be the location of the next major earthquake in the United States, because they are speculating on the core point of the San Andreas fault.
According to many scientific researchers in the United States, the southern end of the San Andreas fault, which is more than 1,300 kilometers long, may be the location of earthquakes where the fault fluctuates up and down, resulting in an abnormal state. However, scientists cannot evaluate how powerful the earthquake will occur at this location. What is now observed is a record of geometric changes in the location of the fault zone.
According to the scientific paper of lithosphere , scientist Susanne Jänecke gave a detailed explanation of the geological changes of the San Andreas fault in Southern California, , and about 30 kilometers of southern region. They found lithospheres with high faults, with a fault width of about 1 to 4 kilometers, and a shear ladder-like structure appeared about 3 to 5 kilometers above.
U.S. geologists said that the newly discovered fault zone Durmid ladder structure is at least 25 kilometers long, with dozens of right-side inverse faults and hundreds of left and right cross-section faults, and the ladder structure develops in the northwest, extending from the San Andreas fault in the northeast to the east coast coast fault zone area.
Scientist Coachella Valley observed through data collection that the East Coastline fault is a huge fault zone, and the structural pattern extends southward to the Durmid step structural area, and finally overly at the southern end of the San Andreas fault, a strike-slip fault zone of several kilometers appeared.
Scientific description, the stepped fault zone of the San Andreas fault is likely to produce super earthquakes, such as the 7.7-magnitude Kaikura earthquake in New Zealand in 2016. The range of the stepped fault zone is also very large, with a width of at least 25 kilometers and a length of about 150 kilometers. The interaction between a large number of fault zones may cause ground fault disasters. Therefore, this problem in the San Andreas fault zone in the United States may be a precursor to a super earthquake. In addition, the American Geological Society also announced that it may be the location of the next major earthquake in the United States.
