Underground Gold Mine Activity Triggers 3.5 Magnitude Earthquake in Victoria

A magnitude 3.5 earthquake was triggered by underground activities at Fosterville Gold Mine in central Victoria. The quake, felt by 47 individuals across the state, was deemed minor by Geoscience Australia, with no significant damage anticipated. The mine confirmed the event as ‘mine-induced seismicity’ and is actively engaging with the community regarding safety measures.

An underground gold mine activity in central Victoria has triggered a magnitude 3.5 earthquake, occurring at 6:41 AM at the Fosterville Gold Mine, located roughly 26 kilometers northeast of Bendigo, as reported by Geoscience Australia. Tremors were felt by 47 residents statewide, with reports extending as far as Glen Huntly in Melbourne. Senior Seismologist Jonathan Bathgate characterized the quake as minor, noting that it was unlikely to cause any damage or further aftershocks due to its size. Bathgate explained, “The shaking associated with an earthquake of this size would be relatively short-lived and wouldn’t be expected to cause any damage.” He further elaborated that individuals often hear the quake more than they feel it, resulting in a loud boom or short jolt before it subsides. Fosterville Gold Mine has acknowledged the occurrence of a “mine-induced seismic event” attributed to their activities, stressing that they have safety measures in place to address such situations. The mine’s representative indicated their awareness of community concerns, stating that their community engagement team was available for any inquiries. Currently, the Fosterville Gold Mine, which is operated by Agnico Eagle Mines Limited, is evaluating the event’s implications. The mining operation is noted as the largest gold producer in Victoria, with its activities impacting rock pressure, potentially leading to ground vibrations. As of this year, Geoscience Australia recorded 38 earthquakes in Victoria, ranging from magnitudes 1.4 to 4.3, marking the state as one of the more seismically active regions in Australia. Bathgate confirmed that Australia regularly experiences minor quakes, yet larger events like this year’s magnitude fours occasionally arise. The Victorian State Emergency Service has advised residents to drop, take cover, and hold on during such occurrences.

The incident reflects the complex relationship between industrial activities, particularly mining, and seismic activity. Underground mining techniques can alter geological pressure, leading to vibrations similar to natural earthquakes. Fosterville Gold Mine, operated by Agnico Eagle Mines Limited, is recognized as the largest gold producer in Victoria, instigating interactions with the community regarding safety and seismic monitoring. Monitoring systems are in place to track such events, assisting in distinguishing between natural seismic movements and those induced by mining operations.

The magnitude 3.5 earthquake in central Victoria serves as a reminder of the effects of mining activities on geological stability. With appropriate safety protocols and community engagement initiatives, the Fosterville Gold Mine aims to address concerns raised by local residents. Continuous monitoring of seismic activity in Victoria highlights the importance of understanding the dynamics between industrial operations and natural tectonic processes, contributing to community awareness and preparedness.
