A series of tremors measuring 4.6 on the Richter scale broke out in the district at 9:42 pm Monday and lasted for about three seconds, said Le Van Tuan, chief of the district People's Committee's Secretariat.
Thousands of locals rushed out of their houses in panic after they heard loud blasts and felt the ground shaking, houses' walls cracking, and things inside the houses falling, Tuan said.
"Many items on a table in my house fell down to the floor and my children cried and screamed when hearing explosions that sounded like the sounds of bombings," he said.
Comment: This earthquake, or whatever it was, does not show up on USGS. The recent quakes may be reservoir induced. There was a similar earthquake September 4th, 2012, that also wasn't registered on USGS. Of course, this in itself isn't proof that there wasn't an earthquake - nor can it be ruled out that some type of 'overhead activity' could have caused the loud explosions.
