Map of the epicenter of the earthquake that occurred tonight (February 3) in Chuong My district, Hanoi. According to the Earthquake Information and Tsunami Warning Center (Institute of Geophysics - Vietnam Academy of Science and Technology), at about 19:5241 on February 3, an earthquake with a magnitude of M = 2.6 occurred at the location with coordinates 20.860 degrees North latitude - 105.582 degrees East longitude, with a focal depth of about 8 km. Earthquake occurred in Chuong My district, Hanoi. On the same day, at about 12:4653, an earthquake with a magnitude of 2.6 occurred at the location with coordinates 14.863 degrees North latitude, 108.157 degrees East longitude, with a focal depth of about 8.2 km. The earthquake occurred in Kon Plong district, Kon Tum province, with a natural disaster risk level of 0. According to Dr. Nguyen Xuan Anh, Director of the Institute of Geophysics, the earthquake in Hanoi is different from the type of induced earthquake that occurred in Kon Plong district, Kon Tum province. The induced earthquake occurred due to the water accumulation process of the hydroelectric reservoir affecting the fault system deep underground. The earthquake in Hanoi is considered a natural earthquake that occurred on the Red River fault system. Dr. Nguyen Xuan Anh said that although it is not located in the Pacific earthquake belt like Japan and the Philippines, there are many areas in Vietnam with active faults. The most notable is the Northwest, where there are many active faults such as the Dien Bien - Muong Lay fault, the Song Ma - Tuan Giao - Lai Chau fault. Hanoi and neighboring areas are located in the Red River fault zone, a fault zone that is in a quiet period with a low risk of earthquakes. The earthquake that occurred tonight (February 3) in Chuong My was a small earthquake, with a natural disaster risk level of 0. However, some people living in Chuong My and My Duc districts (Hanoi) may have felt the shaking. The last time in Hanoi, on March 25, 2024, an earthquake of magnitude 4.0 occurred in My Duc district. According to statistics over the past 100 years, within a radius of 50km from this epicenter, 43 earthquakes with magnitudes ranging from 2.5 to 5.3 have been recorded. In particular, an earthquake with magnitude M = 5.3 was recorded in 1958 in Yen Lac district, Vinh Phuc province. Mr. Nguyen Xuan Anh also said that in the coming time, it is necessary to continue monitoring as well as have more in-depth and updated studies on earthquake risk zoning for localities, in order to update and supplement the seismic resistance map nationwide. From there, there are the latest recommendations for localities in the issue of construction works. Also related to the earthquake situation, according to statistics from the Institute of Geophysics, in January 2025 alone, the whole country recorded about 30 stimulated earthquakes with magnitudes from 2.5 to 4.2, mainly concentrated in Kon Plong district (Kon Tum) and Nam Tra My district (Quang Nam). Notably, on January 27, there were 8 consecutive earthquakes, on January 9 there were 6, with the strongest being 4.2. Hoang Giang See more
