3.9 magnitude earthquake recorded in northern Vietnam
VOV.VN - An earthquake measuring 3.9 on the Richter scale shook Da Bac district of Hoa Binh province, a mountainous locality in the north of Vietnam, on December 14.
The earthquake jolted the area at around 3pm at the depth of 12km, said the Earthquake and Tsunami Warning Centre under the Institute of Geophysics of Vietnam.
The quake caused no disaster risk, and scientists are keeping a close watch on its developments, said the centre.
In late November a 3.0 magnitude earthquake also hit Ha Giang province, another mountainous locality in the north of Vietnam.
Hoa Binh and the northwestern provinces are the places with the most frequent seismic activity in Vietnam. This area has many highly active faults such as the Dien Bien - Muong Lay fault, and the Ma River - Tuan Giao - Lai Chau fault.
