BANGKOK — When the earthquake that hit Myanmar sent its tremors to Thailand, Naruemon Thonglek didn’t immediately know it also had collapsed a high-rise building under construction in Bangkok.

Seeing images of the debris on television news later, Naruemon immediately recognized the building where her longtime Burmese partner, his son and four of her friends had worked for the past month.

At least 18 people died in Bangkok, Thailand’s capital, more than 800 miles from the center of the magnitude 7.7 quake in Myanmar on Friday, which killed more than 1,700 people there.

In Bangkok, 78 people remain missing. Thai authorities are racing against time to find anyone left alive under the ruins as the crucial 72-hour mark passes. While the authorities have said they detected possible sounds of life, so far only one person was pulled alive from the rubble.

Among those missing are the mother and younger sister of Chanpen Kaewnoi, who had been working at the site for a couple of months. – The Associated Press
