Government spokesman Jirayu Huangsub said in Chiang Mai on Monday that the March 28 earthquake in Myanmar affected three buildings in Chiang Mai.
One was Duangkamol condominium in Muang district. The eight-storey building has 102 units and is more than three decades old. It was evacuated and cordoned off due to distortion and structural cracks seen on the first floor. Public works officials will instruct the property owner to improve the building, Mr Jirayu said.
The other two were 22-storey condominium buildings and showed only cosmetic damage. The buildings were evacuated pending repairs, he said.
