Quake chaos

A powerful earthquake rattled 24 provinces, including Bangkok, where a 30-storey building under construction collapsed, sending a massive cloud of dust over Kamphaeng Phet 2 Road.

Office workers and residents in low- and high-rise buildings across the capital rushed to open spaces as the tremors, lasting about a minute, shook the city.

At Siriraj Hospital, medical staff and nurses swiftly evacuated patients from buildings as a precaution.

The quake also affected numerous high-rise structures.
