Overview

• The collapse opened a roughly 50‑meter‑deep hole about 30 by 30 meters on Samsen Road in front of Vajira Hospital, swallowing a crane and exposing underground structures.
• No injuries were reported, and Bangkok’s governor said three vehicles were damaged as the roadway gave way and utility poles fell into the cavity.
• Authorities declared an exclusion zone, evacuated nearby buildings including a police station, cut electricity and water, and shut the road to traffic.
• Vajira Hospital suspended outpatient services for at least 48 hours as emergency and inpatient care continue, with local reports saying about 3,500 appointments were canceled.
• Officials say the cause remains under investigation, with initial findings pointing to earth movement and underground water at the junction of a tunnel and station works as crews work to stabilize the site during monsoon-season rains.
