Underground Gold Mine Causes Magnitude 3.5 Earthquake in Victoria

A magnitude 3.5 earthquake was triggered by underground activities at Fosterville Gold Mine in Victoria. The event, occurring at 6:41 AM, was reported by residents up to 26 kilometers away. Geoscience Australia and Fosterville officials confirmed the quake’s minor nature and reassured the community of safety protocols in place.

An underground gold mine in central Victoria was responsible for a magnitude 3.5 earthquake, recorded at 6:41 AM by Geoscience Australia. The earthquake originated from the Fosterville Gold Mine, approximately 26 kilometers northeast of Bendigo, affecting residents in various locations, including Glen Huntly in Melbourne. Senior Seismologist Jonathan Bathgate noted that the earthquake was minor and unlikely to cause damage, with reports from 47 individuals who felt the tremors across the state. Bathgate highlighted that such small earthquakes often produce more audible sounds than significant shaking, likening the experience to a loud boom or brief jolt. Fosterville Gold Mine confirmed that the seismic activity was classified as a “mine-induced seismic event” which occurs due to the mining operations rather than tectonic movements. A spokesperson emphasized the safety of personnel and the existing protocols to manage such situations. They also reassured the community, highlighting the availability of a dedicated engagement team for addressing any public concerns. The mine is currently reviewing the seismic occurrence, underscoring the complexity and intricacies associated with mine-induced seismicity. Agnico Eagle Mines Limited operates Fosterville and is Victoria’s largest gold producer. As part of their operations, the mine employs an underground seismic monitoring system to track such events. This year alone, Geoscience Australia has recorded a total of 38 earthquakes, ranging from magnitudes of 1.4 to 4.3, emphasizing that Victoria is among the states in Australia with notable seismic activity. Bathgate added that earthquakes, while often minor, can vary in magnitude, occasionally exceeding the threshold of 4. In response to the seismic event, the Victorian State Emergency Service reminds residents to correctly respond during earthquakes by dropping to the ground, taking cover, and holding on. This promotes safety and preparedness for individuals residing in earthquake-prone areas.

This report pertains to recent seismic activity in Victoria, specifically relating to an earthquake caused by mining operations. The shaking, while perceivable to the public, is categorized by experts as a minor earthquake, usually resulting from mining-induced changes to underground pressure. Fosterville Gold Mine is an important site, operated by a Canadian mining company, and its activities significantly contribute to the regional economy while simultaneously impacting geological stability. The continued monitoring of seismic activities in Victoria underlines the importance of geological and emergency preparedness in areas with notable mining operations.

In conclusion, the magnitude 3.5 earthquake in central Victoria was a result of activities from the Fosterville Gold Mine, marking an event that is classified as minor by experts. While the seismic event raised concerns among individuals, authorities and the mining company reassured the public regarding safety measures and protocols in place. Continuous monitoring of seismic activities reinforces the need for preparedness among residents, particularly in regions known for mining operations.
