. On the earth, the global earthquake zone activity seems to have been in a high incidence period. It is hard to say whether 2018 will be a year of high incidence of earthquakes. Although prediction is like this, prediction is also a matter of probability. The earthquakes in additional plates caused by earthquakes in the entire fault zone have begun to become prominent. Compared with the recent days, seismic belts around the world have been much more active, including the Chilean fault subduction zone in the largest earthquake in history.
According to data from the US earthquake monitoring network, on April 12, there were three major earthquakes in Japan in one day, with magnitude 4.8, magnitude 4.9 and magnitude 5.1 respectively. The two are in the direction of the Japanese trench, with one in the northwest of Japan. Scientists once proposed such a correlation: after each major earthquake, earthquakes in distant areas may be triggered, and these three earthquakes may be related to the magnitude 6.1 earthquake in Japan.
In the scientific record, as an active seismic zone around the world, Japan has also given a lot of research technology in recent years to support the prediction of earthquakes. The key Japanese trench areas are also the most concerned. As early as a year ago, Japan responded to the low-frequency vibrations in the trench. Scientists from the University of Tokyo in Japan proposed to install 12 seismometers for underwater monitoring and conduct real-time monitoring. Once a pre-earth earthquake occurs, Japan is likely to be swallowed up most areas, because the scientifically predicted trench earthquakes are all above magnitude 9.
Through scientists' monitoring of earthquakes, we can also find that our Pacific Rim seismic belt seems to become active, of course, this is in progress regardless of location. For example, Japan, Chile, and , Papua New Guinea, and other areas are all earthquakes of magnitude 6 or above, but the scientific community has not given this conclusion whether it is related to the activeness of our earthquake belt.
According to scientific records, Japan and Chile are one of the active areas in the world's major earthquake zones, with several super earthquake records in history. Papua New Guinea is also a newly added high-incidence earthquake area. There are small earthquake fluctuations almost every day, and it has become one of the new active earthquake areas ever.
From a scientific data perspective, the activity of earthquakes can be said to have fluctuated a little high-magnitude recently. Has our earthquake zone really entered a period of high incidence? Will there be a new major earthquake? The last two major earthquakes have been presented in the major earthquake areas in Japan and Chile. Whether there will be stronger super earthquakes next time has not been given a clear explanation or prediction at present.
