A sinkhole roughly 8–10 m wide and several metres deep has opened on the AJ Burkitt Reserve sporting oval in Heidelberg, directly adjacent to the North East Link tunnel alignment in Melbourne’s northeast. Victorian Infrastructure Delivery Authority has confirmed the “surface hole” is in the vicinity of active tunnelling operations, leading to a work pause while engineers and emergency crews carry out geotechnical investigations and monitoring. No injuries or structural damage have been reported, but the area remains fully cordoned off pending cause determination and stability assessment.

A magnitude 7.8 earthquake struck offshore Mindanao, Philippines, at a depth of about 32 km, killing at least 19 people and injuring more than 130 across Surigao del Sur, Davao Oriental and neighbouring provinces. Strong shaking triggered widespread liquefaction, lateral spreading and coastal slope failures, damaging bridges, port facilities and low-rise reinforced concrete buildings with soft-storey behaviour. Engineers are prioritising rapid assessment of pile-supported structures on reclaimed land, stability of coastal embankments and the integrity of lifeline corridors linking key mining and agricultural areas.

South West Water has been fined £1.85M at Exeter Magistrates’ Court after a Cryptosporidium contamination at the Hillhead treatment works left tens of thousands of Devon customers without potable tap water in summer 2026. The DWI prosecution centred on failures in disinfection and monitoring barriers required under the Water Supply (Water Quality) Regulations, including inadequate protozoa control and delayed public notification. Other water companies are now ramping up enforcement and risk reviews of treatment works, with particular focus on UV systems, filtration integrity and contingency planning for microbial outbreaks.
