	1989 Newcastle earthquake - Wikipedia, the free encyclopedia
		The 1989 Newcastle earthquake was a magnitude 5.6 earthquake occurring on Thursday 28 December 1989, at 10.27am.
		The Newcastle earthquake was caused by a build up of intra-plate tension in the southern part of the Indo-Australian Plate.
		If the earthquake had struck during the evening when 2000 people were expected at a pop concert at the Workers Club, or if it had happened a month later when thousands of students had returned to school, a great many more deaths and injuries could have resulted.

	Newcastle, New South Wales - Wikipedia, the free encyclopedia
		Newcastle is the sixth largest city in Australia and the second largest in the state of New South Wales.
		On December 28, 1989, Newcastle experienced an earthquake measuring 5.6 on the Richter scale which killed 13 people, injured 162 and destroyed or severely damaged a number of prominent buildings which had to be subsequently demolished.
		The estimated population of the City of Newcastle at June 2004 was 145,633 (Australian Bureau of Statistics), but its neighbour, the City of Lake Macquarie, was actually larger, with an estimated 189,196 residents as of June 2004 (ABS).

		At 10.27am on the 28th December 1989, Newcastle, Australia's sixth most populous city, was devastated by a moderate earthquake measuring 5.6 on the Richter Scale.
		1989 earthquake effects were felt from: Albury, Cooma and Bermagui, in the south; to Temora and Narromine in the west; and Coonabarabran, Inverell, Armidale, Coffs Harbour, in the north (up to 550km from Newcastle).
		Newcastle revealed that a lethal earthquake can occur in a part of Australia traditionally considered of low seismic risk and that there is a strong correlation between geological conditions and potential for damage.

	Earthquake Damage Repair and Strengthening of Christ Church Cathedral, Newcastle NSW
		Intraplate earthquakes had previously occurred in Australia in sparsely populated regions and, according to the applicable Australian Standard in 1989, Newcastle was located in a "zero" seismic zone, as was most of the populated eastern seaboard.
		One of the big differences, of course, is that in Newcastle the energy was released at a depth of about 14 km beneath the surface: typical interplate earthquakes occur at depths of the order of 100 km, so there is a lot more between them and the surface to absorb and deflect the energy.
		The impact of the 1989 Newcastle earthquake and its effect on the physical fabric and social history of the Cathedral enhances the historic nature of the Cathedral as a centrepiece of cultural sentiment for the people of Newcastle, the region, the State and the nation.

	Mineral Resources - Minfact 21
		Earthquakes occur throughout the world, but mostly along narrow belts, from a few tens to hundreds of kilometres wide, that mark the boundaries of the lithospheric plates.
		If we are to minimise the damage from future earthquakes, we must be able to estimate the risk of them happening, so that buildings can be designed and constructed not to collapse during their expected life in the event that an earthquake does occur.
		In assessing seismic hazard (or expected intensity), the key factors in forecasting ground movement are the magnitude of the earthquake, the distance from the earthquake hypocentre, and the soil conditions.

	Earthquake hazard assessment (Site not responding. Last check: 2007-11-02)
		The extrapolated earthquake rates and information on how fast ground shaking decays with distance is used to assess the long term earthquake hazard in engineering terms (typically a horizontal ground acceleration with a 10% probability of exceedance in a 50 year interval).
		This "probabilistic" earthquake hazard assessment method ignores any knowledge of the physics of earthquakes and may fail to predict future areas of high hazard as illustrated by the occurrance of the large Tennant Creek earthquake in an area considered to be seismically quiet.
		Collaborative research between QUAKES and Chinese groups presented at international conferences during 2000 indicates that both the Newcastle 1989 earthquake and the Burra SA 1997 earthquake were forecastable in the intermediate-term (months to a year prior to these events).

		Earthquakes are the sudden fault movements that occur when the stress along a fault has built up sufficiently to overcome the frictional resistance which opposes slip.
		The Queensland earthquake map shows that the State is seismically active and suggests the highest hazard region lies along the populated eastern coast and near offshore regions.
		For example, the occurance of few earthquakes in any given region may be due to the inability of the seismic network to detect earthquakes, low seismicity and hazard, or a period when little stress is being relieved through small earthquakes and a large event is about to occur.

		This earthquake proved that even Australia is not immune from damaging earthquakes causing significant human and economic loss.
		Until recently Newcastle was a steel manufacturing city, (BHP Steel closed late 1999) but at the time of the earthquake the steel mills were not severly damaged and gas and electricity sub stations did not incur major damage.
		The collapse of the Newcastle Workers Club began at the top of the club causing the building to cascade into itself trapping patrons and workers within the building.

		The debris which blocked our way in the dark were parts of a Grand Piano which had stood in the lounge before the earthquake, and now stuck firmly halfway into the mouth of the mine shaft.
		We later established that it was 4.5 metres across and 40 metres downwards to the bottom of the coal mine.
		According to my estimation, the earthquake shock waves had first forced the water in the coal mine up the mine shaft and then dropped the column of water all its way back down the mine.

	Print the story (Site not responding. Last check: 2007-11-02)
		Earthquakes are caused by sudden and violent movement along faults and most occur at the edges of the huge tectonic plates due to slow movement of these plates relative to one another.
		Scientists had long understood why earthquakes happen where tectonic plates meet (the plates are forced against each other by movements in the mantle beneath the Earth’s surface), but the causes of earthquakes — such as the 1989 Newcastle earthquake — in apparently ‘safe’ areas in the middle of the plate had remained a mystery.
		The research by Dr Schellart and colleagues in Melbourne and the United States showed these earthquakes were caused by transfer of forces generated at the plate boundaries, in particular near Sumatra, where the subducting Indian Ocean transmits up to 10 per cent of its force back to the surface.

		Four years after the 1989 Newcastle Earthquake, the city's administrators advocated that many old buildings would need to have seismic upgrading to satisfy the new earthquake code.
		Incidentally, "anticipated" earthquakes in a well known seismic zone may not necessarily be classified as an "unexpected" natural disaster.

	EARTHQUAKE DAMAGE MITIGATION GUIDELINES
		Earthquakes are caused by the differential movement of the tectonic plates which form the earth's crust.
		These types of earthquakes are limited to about the top 50 kilometres of the earths crust, are random in their location, and are generally smaller in magnitude, whereas intraplate earthquakes that are associated with tectonic plate movements may be reasonably determined in there location and magnitude.
		Specific pockets where earthquakes have occurred have higher hazard ratings while western areas due to the lack of earthquake records are considered as having a low hazard rating.
