Earthquake off the coast of New South Wales.

On Monday 10 September 2012, slightly before 4.25 pm, Geoscience Australia recorded a Magnitude 3.2 Earthquake roughly 60 km of the coast of New South Wales, at or close to the seabed (which may reflect a submarine landslip). This is to small and to far offshore to present any danger, and Geoscience Australia estimate that it should not have been possible to feel it from land. However local newspaper the Express Advocate was reportedly 'inundated' by reports from people who felt the quake, and the United States Geological Survey received witness reports from as far away as Sydney and Newcastle.

Witness statements can help geologists to understand Earthquakes and the geological processes that cause them; if you felt this quake you can report it to Geoscience Australia here.
