On 22 January 1988, three large earthquakes were felt in Tennant Creek. The smallest occurred at 10:06am CST and registered a magnitude of 6.3 on the Richter Scale, whilst the largest occurred at 9:35pm, registering 6.7.

Whilst no one was seriously injured, the quake jolted furniture and created cracks in established walls.

The quakes were felt in Darwin, and effects of the largest quake were noted in Cairns, northern Queensland, and even in high-rise buildings in the capital cities of Perth and Adelaide.

The quakes' epicentres were located approximately 40km southwest of Tennant Creek, limiting the cost of the quake to a mere A$1.2 million, with the main damage being to a high pressure gas pipeline from Alice Springs to Darwin. The quake also resulted in a surface rupture up to a metre high and two metres wide, extending for 35km.

Tennant Creek is a small town of less than 4,000 people on the Stuart Highway in Australia's Northern Territory, approximately 1000 kilometres south of Darwin, and 500 kilometres north of Alice Springs.

The town is surrounded by sandy desert, grassy plains, flat-topped hills and granite boulders. Prior to 1987, there was no history of earthquakes occurring in the region.

The first quake occurred on 8 January 1987 and registered 5.4 on the Richter Scale.
