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.

Workers at the Fukushima Daiichi and Fukushima Daini nuclear power plants were ordered to evacuate to higher ground on 20 April after offshore seismic activity triggered earthquake and tsunami warnings. Plant operations shifted to emergency protocols, with on-site staff moving from low-lying coastal facilities and seawall areas to designated elevated shelters above projected inundation levels. The incident reinforces the need for robust vertical evacuation routes, redundant power and cooling systems, and clear egress planning for nuclear and other critical coastal infrastructure in tsunami-prone regions.

Completion of a three-year national programme to enhance UK surface water flood forecasting marks a step change in predicting intense, short-duration rainfall events that overwhelm urban drainage and highway networks. The upgraded capability is expected to give local authorities, highways agencies and emergency planners earlier, more location-specific warnings for pluvial flooding than existing river and coastal systems, supporting targeted deployment of temporary defences and road closures. For civil and drainage engineers, this should feed into more dynamic operation of combined sewers, attenuation basins and SuDS, and better calibration of design storms against real-time risk.
