According to the Center for Earthquake Reporting and Tsunami Warning, the first quake, measuring 4.5 on the Richter scale, has the potential to create a Category 2 disaster risk, causing many homes to shake. This earthquake occurred at 9:22 am 36 seconds this morning (March 14) in Hanoi time in Dien Bien Dong district of Dien Bien province with a depth of about 13.2 km, coordinates: 21.123N-103.184E .

Right after that, at 11:52 a.m. 00 a.m. this morning (Hanoi time), another 3.4-magnitude earthquake continued to occur in Dien Bien Dong district with a depth of about 8.1km. The damage caused by the two earthquakes is not yet available. However, according to people’s reflection, many places felt the house shake clearly.

According to experts, after the main trigger, there may be more smaller earthquakes, called aftershocks. Therefore, this area may receive more earthquakes smaller than 4.5 in the near future.

According to Dr. Nguyen Xuan Anh, director of the Center for Earthquake Alerts and Tsunami Warnings, the Northwest region is home to many highly active faults such as the Dien Bien – Muong Lay fault, the Song Ma – Tuan Giao fault. Lai Chau. This place has recorded many strong earthquakes such as the 1935 earthquake with a magnitude of 6.9 in the Dien Bien basin, a 6.7-magnitude earthquake that occurred in Tuan Giao town in 1983 and a strong earthquake. 5.3 degrees in Dien Bien Phu city in 2001.

Mr. Xuan Anh suggested that people here need to beware of possible large earthquakes. The construction of buildings and houses should meet seismic resistance requirements that have been developed and recommended by the Institute of Geophysics. fox.

Mr. Xuan Anh also said that in the coming time, there should be further and more updated studies on earthquake risk zoning for localities in order to update and supplement seismic resistance maps across the country. From there, there are the latest recommendations for localities in the construction of works. “Earthquake is an unpredictable problem, there are geological areas, faults that lie dormant for a long time and then become active again. Therefore, localities need to comply with the warning requirements on seismic resistance to minimize the consequences if it occurs,” said Xuan Anh.
