Aftershocks continued after the 7.2-magnitude earthquake in Hualien, Taiwan, on the 3rd of this month. Aftershocks are still occurring this morning. The Earthquake Forecasting Center of the Taiwan Meteorological Administration pointed out on Tuesday (23rd) that the number of aftershocks after the major earthquake has exceeded 1,000, and the total number of aftershocks above magnitude 5 48 times. Wu Jianfu, director of the Earthquake Forecasting and Forecasting Center of the Meteorological Administration, said that the earthquake just started on Monday (22nd) afternoon and is now at its peak, with aftershocks continuing to occur in the next six months to a year. Lee Sidi, a professor at the Institute of Applied Geology at Chung-Ang University, said that the frequency of aftershocks in the past two days has been a bit abnormal, and he is worried about the occurrence of a giant trench earthquake.

Aftershocks have exceeded 1,000 times and magnitude 6 cannot be ruled out

Wu Jianfu said at a press conference today that more than 180 earthquakes occurred in Hualien from Monday evening to 8 a.m. this morning, all of which were aftershocks. The epicenter moved south to the Shoufeng and Fenglin areas of Hualien, which was a post-earthquake stress adjustment. He pointed out that aftershocks after major earthquakes will shrink and decrease over time, but they may still occur in greater numbers. Based on the experience of the 921 earthquake that occurred on September 21, 1999, there will still be aftershocks in the next six months to one year, and the scale will gradually shrink, but it may still reach magnitude 4 or above, and even magnitude 6 cannot be ruled out. People should take precautions Disaster preparedness.

If a giant trench earthquake occurs, “the building will collapse completely.”

Li Xidi posted on social media on Monday that if a giant trench earthquake occurs in Taiwan, not only will the shaking last for a long time, but the amplitude of the swing will also be large, and “the building will collapse completely.” He gave the example of the Hualien earthquake at the beginning of this month, which shook Taipei for 1 minute; during the 921 earthquake, Taipei shook for about 1.5 minutes. However, if a giant earthquake in the trench occurs, Taipei may shake for up to 3 minutes, and the building will swing even more. “A house damaged in an earthquake that shakes for 1 to 2 minutes may collapse after shaking for 3 minutes,” warns Taiwan Prepare early to reduce disaster damage.
