An earthquake measuring 3.2 on the Richter scale shook Moc Chau District of Son La Province in northern Vietnam on Thursday morning.
The quake occurred at 1:37 am, the Institute of Geophysics said, adding that the tremor did not pose a disaster risk.
Many residents of Moc Chau District reported that they felt the tremor while they were sleeping.
“I was waken up because the bed shook violently, making loud noise for about 30 seconds,” a local named Tuan said, adding that this is the third earthquake in the last five days.
The first two quakes occurred on October 2 and 3, measuring 3.3 and 3.1 on the Richter scale, respectively.
The Earthquake and Tsunami Warning Center under the Institute of Geophysics said it continued to monitor aftershocks.
In 2020, Moc Chau District was also hit by several quakes, including a magnitude-5.3 one on July 27, 2020. People living at high-rises in parts of Hanoi and north-central Thanh Hoa Province, about 160km away from Moc Chau, could also felt the vibration.
Moc Chau is vulnerable to earthquakes as it is located in the fault zone of the Da River.
The district may experience more powerful quakes in the future, according to forecasts.
