As many as 32 earthquakes have shaken Kon Plong, a district in Vietnam’s Central Highlands, over the past 24 hours, according to the Institute of Geophysics.

Since the early hours of Monday morning, the upland district in Kon Tum Province has been rocked by 11 quakes, the institute said, elaborating that the 10th one took place at 6:56 am at a depth of some 8.1 kilometers and measured 2.6 on the Richter scale.

The district was jolted by up to 21 quakes on Sunday, including a magnitude-five one which occurred around noon and caused vibrations in many neighboring provinces and cities such as Binh Dinh, Phu Yen, Hue, Da Nang, and Quang Nam in central Vietnam.

Authorities said that this magnitude-five quake posed a level-two disaster risk, with multiple houses near the quake’s epicenter in Kon Plong suffering cracks due to shaking.

The quake, which struck at 11:35 am at a depth of 8.1 kilometers, was also felt in Thailand's Ubon Ratchathani and Sakon Nakhon Provinces.

The Institute of Geophysics explained that the magnitude-five quake was induced by human activity.

The agency also noted that the frequency of quakes in the province showed no signs of decreasing.

Its Vietnam Earthquake Information and Tsunami Warning Center is closely monitoring these tremors.

The institute is operating 11 monitoring stations in Kon Tum and undertaking in-depth research to assess seismic activity in this upland province.

In Vietnam, tremors with magnitudes ranging from five to 5.9 are assessed as moderate and capable of causing minor to moderate damage.

Meanwhile, quakes with magnitude-4 to -4.9 are deemed small tremors.
