Kon Plong District in Vietnam’s Central Highlands province of Kon Tum was hit by nine tremors on Friday, with the strongest one measuring 4.4 on the Richter scale, according to the Vietnam Earthquake and Tsunami Warning Center under the Institute of Geophysics.
The ninth tremor, with a magnitude of 3.0, occurred at around 12:47 pm.
Previously, the eight other quakes, measuring between 2.6 and 4.4 on the Richter scale, hit the district from 5:00 am to 10:30 am, with the 4.4-magnitude one recorded at 7:45 am.
Residents in neighboring areas such as Kon Ray District and Kon Tum City in Kon Tum Province and Chu Pah District in Gia Lai Province also felt the tremors.
The Institute of Geophysics is monitoring the aftershocks of these tremors, which posed no disaster risk.
Recently, Kon Plong was struck by six other tremors on Tuesday and Thursday.
Since February 2021, quakes have become more frequent in this Central Highlands district than before, the Institute of Geophysics said.
The largest one to hit the district was reported in August last year, measuring 4.7 on the Richter scale.
The district will likely experience stronger quakes with a 5.5 magnitude, the institute forecast.
In Vietnam, earthquakes measuring between 2-2.9 and 3-3.9 are classified as weak. These will cause almost no damage to humans and properties.
Those with magnitudes of 4-4.9 are moderate quakes, which will slightly shake household facilities but cause almost no damage.
