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.

An AI-driven data analysis model has identified up to 1.2M buildings in England located outside existing flood defences and therefore exposed to future flood risk. The model combines Environment Agency flood maps with property location data to pinpoint undefended assets, including homes, critical infrastructure and commercial premises. For civil and geotechnical engineers, the findings signal pressure to prioritise resilience upgrades, reassess design flood levels and drainage capacity, and target nature-based or structural defences to specific high-risk clusters.

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.
