The quakes, measuring between 2.7 and 3.6 in magnitude, occurred between 12 pm and 9. 51 pm local time. The strongest, a 3.6-magnitude tremor at 1821, caused widespread shaking across the region.
Residents in mountainous areas such as Son Tay, Ba To and Son Ha reported noticeable tremors, while shaking was also felt in lowland and coastal areas including Duc Pho, Nghia Hanh, Long Phung and An Phu, as well as My Khe and Dung Quat.
Nguyen Quoc, a resident of An Phu, about 80 kilometres from the epicentre, said his family felt the ground shake several times at around 6.20 pm, accompanied by rattling windows.
“At first, I didn’t think it was an earthquake. But after seeing reports of a 3.6-magnitude tremor and others sharing similar experiences, I realised what it was,” he said, adding that while no damage was reported, the widespread tremors surprised many.
Since 2021, the former Kon Plong District of Kon Tum Province, now part of Quang Ngai, has recorded hundreds of induced earthquakes. The largest, measuring 5.0, occurred on July 28, 2024.
Local authorities said earthquakes have been occurring frequently in recent months, often on a daily basis, though no casualties or damage have been reported.
