Residents across the Barossa Valley were shaken awake in the early hours of Monday morning after a magnitude 2.8 earthquake struck near Tanunda.

The earthquake was recorded at approximately 2:26am on Monday, October 19th, with its epicentre around 1.5 kilometres northwest of Tanunda and approximately 21 kilometres northeast of Gawler.

The tremor registered a magnitude of 2.8. While classified as a relatively minor earthquake, residents close to the epicentre described loud noises, rattling windows and noticeable movement inside their homes.

Reports emerged from across the region, including Tanunda, Nuriootpa, Greenock, Lyndoch, Kapunda, Daveyston and Eudunda, with some residents saying the shaking was strong enough to wake them from their sleep.

In the Barossa Valley Community Chat Facebook group, a post asked whether the region had just experienced an earthquake attracted more than 200 reactions, with locals sharing their experiences.

Nadia, who was in Nuriootpa, described the shaking inside her home.

“Yeah our whole bed and windows rattled probably went for about 10 seconds at Nuri,” she wrote.

Another resident, Sharon, compared the experience to a large vehicle moving through her home.

“That was a big one whole house sounded like truck was driving through it. Scared my big dog onto me in bed, Was a long one also.”

Residents in nearby Greenock reported particularly noticeable noise and shaking, with Sue describing the earthquake as “so loud”, while Tricia said it “felt quite strong.”

The earthquake was also reported by locals further north, including Kapunda and Eudunda, suggesting the tremor was noticed well beyond the immediate Barossa Valley.

Despite the relatively small magnitude, the earthquake was widely felt across the region, with dozens of residents submitting reports to earthquake monitoring services.

The Barossa Valley is no stranger to seismic activity, although most earthquakes recorded in the surrounding region are relatively minor.

The Barossa Valley experienced a magnitude 2.5 tremor near Kapunda in July 2025, which was felt by residents in Nuriootpa, Tanunda, Gawler and surrounding towns. South Australia has a long history of seismic activity, with a magnitude 3.7 earthquake striking near Mount Barker in March 2022, prompting more than 12,000 reports from people who felt the shaking. One of the state’s most significant earthquakes occurred on March 1st, 1954, when a magnitude 5.4 tremor struck Adelaide, damaging around 3,000 buildings and resulting in more than 30,000 insurance claims.
