A massive sinkhole measuring approximately 50 meters deep suddenly opened on a busy road near Vajira Hospital on Samsen Road in Bangkok, Thailand, on Wednesday, causing widespread alarm. Authorities immediately closed off the area as the collapse led to downed electric poles, dangling power lines, and broken water pipes that flooded the vicinity. Cracks were reported in nearby buildings, and social media videos of the incident quickly went viral, showing the scale of the destruction and traffic disruptions.
Bangkok Governor Chadchart Sittipunt attributed the collapse to ongoing underground railway construction in the area. While no casualties were reported, three vehicles were destroyed, and precautionary measures included relocating patients from Vajira Hospital and residents from nearby apartments to safer zones. Electricity and water supplies in the affected area were temporarily shut off to prevent further hazards.
