, China News Service, August 8, according to reports, at 5:28 am on the 8th, a 6.0-magnitude earthquake occurred in Taiwan at 6.0 (Note: Mainland measured magnitude 6.4). The earthquake was 22 kilometers deep in the eastern sea area of Taiwan, and the whole of Taiwan felt. In this regard, Taiwan's meteorological department pointed out that the main earthquake was caused by the Nanyilan crushing zone. In the past, earthquakes with a scale of more than magnitude 6 often occurred at this location. If this is a foreshift, it is not ruled out that there will be earthquakes with a scale of more than magnitude 6.0.
Meteorological department data shows that the maximum earthquake in various places is: Yilan 6, Hualien 4, Beishi 4, Hsinchu 4, Taoyuan 4, Taichung 4, Nantou 3, Miaoli 3, Changhua 3, Yunlin 3, Chiayi 2, Tainan 2, Taitung 1, Kaohsiung 1, Pingtung 1, Penghu 1. Chen Guochang, director of the
Earthquake Measurement and Reporting Center, said that this time, except for the southernmost part of Taiwan and Hengchun, no earthquake was felt, almost all other areas felt shaking.
Chen Guochang said that there were two earthquakes in Taiwan that exceeded magnitude 6.0 this year, which were around the long-term average range, with about 2 to 3 earthquakes in the magnitude 6.0 each year. There will be another time in the second half of the year, and the energy released this time is expected. This is a pretty good phenomenon. There is still a first-magnitude earthquake in Penghu. Penghu is a straight-line distance and it is arriving at Kaohsiung. I have not heard of the disaster yet. I hope that local people in Yilan area near the sea area will be safe.
Chen Guochang said that this area is the area with the most earthquakes in history with a scale of more than magnitude 6. In 1920, the area was located in the broken belt of the Nanyilan tectonics. It has been nearly 100 years since then. The Nanyilan tectonics is a very high earthquake potential.
As for whether there will be aftershocks? Chen Guochang said that if this is a forequake, it is not ruled out that there will be an earthquake with an earthquake of magnitude 6.0 in scale. The energy release this time is still a bit insufficient, but it may not be released today or tomorrow. It is the earthquake that caused the breakage of nearby structures, which will lead to a larger earthquake being connected to the back; if this is the main shock of , the number of aftershocks should not be too many, and the duration should not be too long, and will be closely monitored within a week.
As for whether it is a shallow earthquake? Chen Guochang said that the depth of less than 30 kilometers is shallow, but the Nanyilan tectonic earthquake was often within 20 kilometers.
