HÀ NỘI — Three small earthquakes have hit the northern region this month, scientists say.
The Earthquake and Tsunami Information Centre under the Việt Nam Institute of Geological Sciences said the latest one, of 2.8 Richter magnitude, struck yesterday in Cao Lộc District of the border province Lạng Sơn.
The earthquake’s epicenter lay at 21.875 degrees northern latitude and 106.773 eastern longitude, at a depth of 12km, the centre said.
It said it is closely monitoring the quake, its aftershocks, and related geological activities in the area.
About a week ago, June’s first earthquake, of 3.1 Richter magnitude, occurred in the Việt Nam-China border area near Cao Bằng Province. This quake’s epicenter lay at 22.997 northern latitude and 105.951 eastern longitude, also at a depth of 12km.
A day later, the second earthquake hit Cẩm Phả Town of the northeastern coastal province of Quảng Ninh, with a measured magnitude of 2.8-3.3 Richter.
Nguyễn Hồng Phương, deputy director of the centre, said quakes of this magnitude were “natural activities of the earth.
“The three quakes happened in the mountainous region and have their epicentres lying more than 10km inside the earth, so it would be hard for people to notice anything. They didn’t pose any threat to human lives or properties,” Phương said. — VNS
