A magnitude 3.5 earthquake, caused by activities at the Fosterville Gold Mine in Victoria, was recorded today without significant damage. Geoscience Australia confirmed its minor nature, with no expected aftershocks. The event underscores the connections between mining operations and seismic activity in the region.
In central Victoria, an underground gold mine has triggered a magnitude 3.5 earthquake registered by Geoscience Australia. The quake, localized near the Fosterville Gold Mine approximately 26 kilometers northeast of Bendigo, occurred at 6:41 AM today. It was felt by 47 individuals across the state, with reports extending to Glen Huntly in Melbourne. Geoscience Australia’s Senior Seismologist, Jonathan Bathgate, categorized the incident as minor, indicating that aftershocks are unlikely. He explained, “The shaking associated with an earthquake of this size would be relatively short-lived and wouldn’t be expected to cause any damage.” Additionally, he noted that people often perceive the sound of these events more than the shaking itself, typically described as a loud boom or a brief, impactful jolt. The Fosterville Gold Mine acknowledged the occurrence, labeling it a “mine-induced seismic event.” A spokesperson clarified, “Mine-induced seismicity is complex, the mechanisms are similar to an earthquake, however, they are related to our mining activities.” They emphasized the safety of personnel and the establishment of protocols for such events. In an effort to address community concerns, Fosterville Gold Mine has organized engagement initiatives, including a marquee in Axedale where local residents can voice their inquiries. The mine, operated by Canadian-based Agnico Eagle Mines Limited, is Victoria’s largest gold producer. This seismic event is attributed to the operational alterations affecting rock pressure and vibration within deeper subterranean levels, as outlined on their company website. Geoscience Australia revealed that, so far this year, the state has experienced 38 earthquakes ranging from magnitudes of 1.4 to 4.3. Bathgate remarked, “Victoria, we would consider it to be one of the higher seismicity states in Australia, along with South Australia and south-west WA.” He further noted that minor seismic activity is frequently recorded, with occasional larger tremors, such as the recent events in Victoria. To ensure public safety, the Victorian State Emergency Service advises residents to adopt the Drop, Cover, and Hold On strategy in the event of future quakes.
The event is a clear demonstration of the geological complexities associated with mining activities. Gold mining, particularly in regions like Victoria, alters the pressure exerted on underlying rock structures, which can result in seismic events resembling natural earthquakes. Such occurrences have been noted in Victoria, which is recognized as one of Australia’s more seismically active regions, alongside South Australia and western Australia. The significance of monitoring these activities becomes paramount for both the safety of the workers and the surrounding communities.
In summary, the magnitude 3.5 earthquake in central Victoria resulted from activities at the Fosterville Gold Mine, although it posed no significant threat to safety or property. Continuous monitoring and community engagement remain vital for addressing concerns arising from such mine-induced seismicity. With comprehensive protocols in place, mining operations continue while ensuring the welfare of both personnel and residents in the vicinity. The incident highlights the intricate relationship between mining activities and geological impacts.
