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.

EDF has been granted a six-week extension by the Office for Nuclear Regulation to comply with an improvement notice issued after an incident at the Hartlepool nuclear power plant that left workers hospitalised. The notice concerns shortcomings in safety management and procedural controls during operations at the AGR (advanced gas-cooled reactor) site, where strict radiological and conventional safety regimes are mandatory. Civil and nuclear engineers involved in plant maintenance and modification work can expect tighter scrutiny of method statements, permit-to-work systems and contractor oversight on similar UK nuclear facilities.
