On 24 September, a massive sinkhole, up to 160 feet deep, opened on Samsen Road in Bangkok near Vajira Hospital. The collapse, caused by heavy rainfall and nearby underground train construction, swallowed vehicles and electricity poles. No casualties or injuries were reported, but people living or working nearby were evacuated. The sinkhole caused severe local transport disruption. The immediate outlook includes prolonged road closures, recovery operations, and potential utility outages, highlighting the operational and security risks of urban development during monsoon conditions.
