Singleton, NSW – A magnitude 4.6 earthquake struck the Hunter Valley region of New South Wales in the early hours of Wednesday, April 24, 2025, jolting residents awake across a wide area of eastern Australia, with tremors felt as far away as Sydney and Canberra.
Geoscience Australia reported that the earthquake occurred at 2:55 AM local time near Singleton, approximately 200 kilometers north of Sydney. The quake had a shallow depth of 10 kilometers. Initial reports estimated the magnitude at 5.1 but it was later revised down to 4.6.
While no significant injuries or property damage have been reported, around 3,800 individuals from areas including Canberra and Tamworth reported feeling the shaking. The NSW State Emergency Service (SES) received numerous calls from concerned residents and responded to a single incident of a burst water pipe in Rutherford, near Maitland, where sandbagging was required.
The Hunter Valley is known for experiencing moderate seismic activity, although Australia is not typically prone to large earthquakes. Senior seismologist at Geoscience Australia, Phil Cummins, described the event as "pretty large for Australia" and "significant."
The location of the earthquake's epicenter, approximately 36 kilometers from Liddell, a decommissioned coal-fired power station site proposed by opposition leader Peter Dutton as a potential location for a nuclear power plant, has drawn considerable attention. Dutton had previously identified Liddell as a candidate site under the Coalition's plan to replace aging coal infrastructure with nuclear reactors, making the region a focal point of the national energy debate.
Despite the minimal physical damage caused by the earthquake, its proximity to the proposed nuclear site has immediately reignited concerns regarding the safety of constructing nuclear reactors in seismically active areas. The Hunter Valley has a history of seismic activity, including a magnitude 5.4 earthquake in 1994 near Ellalong and the devastating magnitude 5.6 Newcastle earthquake in 1989, which resulted in fatalities and widespread damage.
In Sydney, residents in high-rise buildings reported feeling the tremors more distinctly due to the amplification of seismic waves in taller structures. Dr. Ehsan Noroozinejad Farsangi, a seismology expert, explained to The Guardian that this heightened sensation in high-rise buildings is a normal characteristic of earthquake effects.
Authorities indicated that aftershocks might be felt in the coming days, although none have been officially recorded so far. The Joint Australian Tsunami Warning Centre confirmed that there was no tsunami threat associated with the earthquake.
Geoscience Australia data reveals that the Hunter Valley region has experienced at least 11 earthquakes of magnitude 3 or greater in the past year, suggesting an increasing trend in seismic activity in the area. The magnitude 4.6 earthquake is considered a continuation of this heightened activity.
This relatively significant earthquake, felt across a large part of eastern Australia, has understandably raised public anxiety. Its occurrence near a proposed nuclear power plant site is likely to significantly influence future discussions on energy policy. Experts emphasize the need for continued monitoring of seismic activity in the region and preparedness for potential future events by the government and relevant agencies.
