Thai authorities said they are investigating why a single office tower under construction in Bangkok collapsed during an earthquake on Friday that otherwise caused limited damage in the capital.

Bangkok governor Chadchart Sittipunt visited the site as heavy equipment pulled away rubble from the 30-story building in hopes of finding survivors among the 78 people still missing.
