Six earthquakes in Hualien, Taiwan


Taiwan’s hualian Shoufeng earthquake, with a magnitude of 5.5 on the Richter scale, occurred last night (the night of the 15th). After the whole station felt the earthquake, there were six more earthquakes in Taiwan since the early morning of today (the 16th). The epicenter of the earthquake was located in Shoufeng Township, Hualian County, with shallow earthquakes. Among the six earthquakes, the largest one was magnitude 4.9. As for the maximum magnitude (earthquake intensity) of 4 (Note: Taiwan Meteorological Department divides the magnitude into 10), they all appear in Hualian County.
According to the report, the six earthquakes are in chronological order as follows:
According to the latest information from Taiwan’s meteorological department, an earthquake with a magnitude of 3.1 on the Richter scale occurred at 5:40 on the 16th, with a focal depth of 8.4km. The epicenter of the earthquake was 20km south by west of Hualian County Government (located in Shoufeng Township, Hualian County), with a maximum magnitude of 2.
At 4:50 on the 16th, an earthquake with a magnitude of 3.8 on the Richter scale occurred, with a focal depth of 7.9 kilometers. The epicenter of the earthquake was 19.1 kilometers (located in Shoufeng Township, Hualian County) to the west by the south of Hualian County Government, with a maximum magnitude of 4.
At 4:13 on the 16th, an earthquake with a magnitude of 3.7 on the Richter scale occurred, with a focal depth of 8.4 kilometers. The epicenter of the earthquake was 19.5 kilometers (located in Shoufeng Township, Hualian County) to the west by the south of Hualian County Government, with a maximum magnitude of 4 in Hualian County and 1 in Nantou County
At 3:20 on the 16th, an earthquake with a magnitude of 4.9 on the Richter scale occurred, with a focal depth of 6.2km. The epicenter of the earthquake was 18.5km (located in Shoufeng Township, Hualian County) to the west by the south of Hualian County Government, with a maximum magnitude of 4 in Hualian County, 2 in Nantou County, 2 in Taichung City, 2 in Yilan County, 2 in Yunlin County, 1 in Taidong County, 1 in Jiayi County, 1 in Zhanghua County, 1 in Xinzhu County, 1 in Miaoli County and 2 in Nantou County.
At 3:16 on the 16th, an earthquake with a magnitude of 4.0 on the Richter scale occurred, with a focal depth of 8.2km. The epicenter of the earthquake was 18.5km (located in Shoufeng Township, Hualian County) to the west by the south of Hualian County Government, with a maximum magnitude of 4 in Hualian County, 1 in Nantou County and 1 in Taichung city.
At 0:56 on the 16th, an earthquake with a magnitude of 3.1 on the Richter scale occurred, with a focal depth of 10.1km. The epicenter of the earthquake was 14.5km (located in Shoufeng Township, Hualian County) to the west by the south of Hualian County Government, with a maximum magnitude of 2.
According to the report, Hualien County has had several successive earthquakes at the same place. According to the Taiwan Meteorological Department, Hualien has always been an area with frequent earthquakes. Two plates, Eurasia and the Philippines, have been squeezed continuously, causing the earth’s crust to be broken. Hualien is in the broken zone, so it is easy to be affected by the release of energy from the earth’s crust, resulting in an earthquake. In the next two weeks to a month, we are afraid that the energy will continue to be released, which does not rule out the possibility of large aftershocks.
