An earthquake struck approximately 53 kilometres SSE of the town of Mansfield (in the vicinity of the township of Woods Point), in the Victorian Alps of Australia on 22 September 2021, at 09:15 local time.

[1][2][6] The earthquake caused minor structural damage in parts of Melbourne and left one person injured.

This zone formed as a result of plate convergence occurring at the eastern boundary of the supercontinent Gondwana during the Neoproterozoic.

[11] The Governor Fault is a large intraplate fault that runs from mid-western New South Wales, along part of the Murray River bed and cutting through Central North Victoria near Barmah to the Victorian Alps near Mount Buller (near the quake epicentre) down toward the Gippsland Basin near the coast at Saint Margaret Island.

The earthquake occurred when elastic strain accumulated on active fault is released in the form of seismic waves that are felt on the surface as shaking.

[2] Tremors were felt in Adelaide, southern New South Wales, Canberra, and as far as Launceston, Tasmania.

[8][17] According to a geologist at the University of Melbourne, the quake produced ten seconds of strong shaking which was felt by people.

[19] On Chapel Street, the earthquake collapsed the top facade of Betty's Burgers & Concrete Co., which is a brick building and left debris across the road.

[21] In Mansfield near the epicentre, there was minor damage to some buildings including a local ambulance centre.

[23] In the town of Mansfield, Victoria, the quake caused some minor damage to buildings, resulting in no casualties.

[22] Initially, state officials and emergency services said no casualties were caused by the earthquake, but a man in Mount Eliza, a coastal suburb in Melbourne, sustained minor injuries.

The earthquake which lasted 20 seconds in the filming studio caught hosts Michael Rowland and Tony Armstrong by surprise.
