Two consecutive earthquakes of magnitude 5 or greater occurred early this morning in the eastern sea. Chen Guochang, director of the Meteorological Office’s Earthquake Observation and Reporting Center, said these two earthquakes belonged to submerged areas. There have been 8 earthquakes of magnitude 5 and higher in the eastern seas so far. Besides the normal energy release, there is another possibility. These can be harbingers of major earthquakes.
Chen Guochang said the 6.1 earthquake on February 7 and the two earthquakes of magnitude 5.5 and 5.7 in the early hours of this morning are all earthquakes generated in the subduction zone. Therefore, the two earthquakes in the early hours of this morning are classified as January 7. Replicas. When a magnitude 6.1 earthquake occurred on February 7, it was predicted that aftershocks of magnitude 4 or more would occur in the next 3-4 days, and this appears to be the case.
Chen Guochang noted that there have been 8 earthquakes with a scale of more than 5 so far this year, and they have all occurred near the Heping Basin. They are all earthquakes in the subduction zone. He also noted that since last year, Earthquakes have occurred more frequently than before. Among them, there are two. One explanation is that it releases energy normally, but not necessarily because large earthquakes occur in submerged areas such as trenches and ocean basins. Earthquakes with a scale of more than 5 have premonitions. Looking at the 311 earthquake in Japan, it happened in the first 7 days. There was a 7.7 earthquake. Japan thought it was the main earthquake, but 7 days later, there was a magnitude 9 earthquake. Therefore, it is not ruled out that these earthquakes of magnitude 5 and above could be harbingers of major earthquakes.
Chen Guochang said that earthquakes suddenly become frequent and occur repeatedly in the same area. We must pay more attention. The Met Office will continue to pay attention to the further development of this area. As for why the national alert for the two earthquakes was not issued in the early hours of this morning, Chen Guochang explained that errors in estimating the earthquakes are inevitable. Please bear with me and we will estimate more accurately in the future.
Chen Guochang said that there are many organizations involved in cell broadcasting. If changes are to be made now, they will have to go through layers of administrative procedures. It is estimated that in the second half of the year, Taipei will adjust to a magnitude 4 earthquake before sending out mobile newsletters, which is the same standard as other counties and cities.
According to statistics, this year there were 8 earthquakes of magnitude greater than 5. They were the 5.7 earthquake in the eastern sea area on January 9, followed by the 5.4 earthquake in the southeast sea area on January 17, the earthquake in 5.2 in the eastern sea. on January 25 and the coastal area of Taitung County on January 28. The 5.0 earthquake, the 5.4 earthquake in the southeast sea area on February 4, the 6.1 earthquake in the east sea area on February 7 and the 5.5 and 5.7 earthquakes in the east sea area on February 9, and the two earthquakes were only 2 minutes apart. The earthquakes became denser and more frequent. Be careful.
