Multiple Earthquakes Strike Northern Vietnam's Cao Bang Province; Experts Urge Safety Measures

Three consecutive earthquakes, with magnitudes ranging from 3.2 to 3.6, have occurred in Cao Bang Province, northeastern Vietnam, from July 30 to August 3. The earthquakes were reported by the Center for Tsunami Warning and Forecasting (Institute of Earth Sciences, Vietnam Academy of Science and Technology). All seismic events were classified with a natural disaster risk level of 0. On August 3 at 3:19:58 PM (local time), an earthquake with a magnitude of 3.2 struck Bao Loc commune, with coordinates at 22.929 degrees North latitude and 105.683 degrees East longitude, and a focal depth of approximately 16.8 km. Prior to this, on July 30 at 7:44:45 PM, an earthquake of magnitude 3.6 occurred in the same commune of Bao Loc. Another earthquake of magnitude 3.2 was recorded on August 1 at 8:51:21 PM in Hung Dao commune. Dr. Nguyen Xuan Anh, Director of the Institute of Earth Sciences, noted that the epicenters of these three earthquakes are located within the influence zone of the Thai Nguyen-Bac Kan-Yen Minh fault system. Scientists from the Institute of Earth Sciences are continuing to monitor and analyze this seismic sequence. Earthquakes in Vietnam are primarily divided into two categories: tectonic and induced. Earthquakes with magnitudes between 4 and 5 are considered minor. During such events, objects indoors may vibrate and make noise, and many people can clearly feel the tremors. Those outdoors might experience mild shaking. Generally, these do not cause significant damage or only minor damage. Dr. Nguyen Xuan Anh recommended safety measures for when earthquakes occur. If indoors, individuals should "Drop, Cover, and Hold On." Specifically, people should lower their center of gravity to avoid falling, get under a table or stand close to an interior wall, use their hands or other objects to protect their head and neck, and stay away from objects that could fall. If outdoors, people should move to an open area, away from tall buildings, power poles, and large trees. If driving, it is advised to reduce speed, stop in a safe location, and avoid bridges, tunnels, and power lines. For schools, offices, and apartment buildings, it is crucial to have evacuation plans, conduct regular drills, and provide clear instructions to prevent panic during shaking.
