A 4.9-magnitude earthquake struck off the coast of South Australia early Tuesday morning, causing noticeable shaking across Adelaide and surrounding areas. The tremor was recorded at 7:48 a.m. local time by Geoscience Australia, with its epicenter located approximately 100 kilometers offshore between Kangaroo Island and the mainland, south of Victor Harbor and west of Kingston South East.

Residents across the region reported feeling the quake, which was also sensed as far north as Kapunda and in Beachport to the south. Geoscience Australia senior seismologist Jonathan Bathgate described the event as a "significant earthquake," noting that while the area has a history of seismic activity, this level of shaking is unusual and explains why it was felt over a wide area.

Despite the magnitude, officials confirmed there was no tsunami risk following the quake. Bathgate cautioned that aftershocks might occur, typically smaller and less frequent, but the possibility of more substantial seismic events cannot be ruled out.

Eyewitness accounts from Adelaide included descriptions of furniture and office equipment moving during the tremor. One resident from Reynella recalled spilling their coffee when their bed suddenly shook, while an office worker on the top floor of a city building said monitors visibly wobbled. In Normanville, a local noted unusual behavior in their animals, reporting that their fish had been lingering at the bottom of their tank in the days leading up to the quake.

The event highlights the seismic potential along the South Australian coastline, a region that, while not frequently affected by earthquakes, remains susceptible to episodes of moderate shaking. Authorities continue to monitor the situation for any further activity.
