An earthquake is the sudden release of energy and ground shaking resulting from rocks breaking and moving along a fault line under stress from plate tectonic forces. The focus is the initiation point of the earthquake deep within the Earth, while the epicentre is the vertical projection of the focus on the Earth’s surface. Earthquakes most commonly occur near the boundaries of tectonic plates, such as around the ‘Pacific Rim of Fire.’ However, they can also occur within stable tectonic regions, like Australia. It is important to remember that large earthquakes can occur anywhere in Australia, and without warning, even in regions of low levels historical seismicity. At 10.27 am on Thursday, 28 December 1989, Newcastle was devastated by an ML 5.6 (MW 5.4) earthquake. This was one of the most significant natural disasters in Australia’s history. This flyer was prepared for the Newcastle Museum to mark the 30th anniversary of this disaster.
