Bangkok Governor Chadchart Sittipunt on Wednesday declared the collapsed road in front of Vajira Hospital a no-entry danger zone and announced seven urgent measures to address the disaster.

Collapse Details and Immediate Action

Chadchart invoked the authority of the Bangkok Metropolitan Administration (BMA) to declare the large collapse site on Samsen Road in Bangkok’s Dusit district a dangerous zone prohibited from entry. The road collapsed around 6.30 am, creating a massive hole approximately 50 metres deep and 30 x 30 metres wide.

Concerns Over Further Rain and Soil Movement

Chadchart also expressed concern that additional rainfall could wash more soil into the tunnel, prompting him to establish a panel to consider measures should further rainfall occur. He explained that the collapse was caused by soil entering the underground metro tunnel at the junction between the tunnel and the station.
