It shifted land, created liquefaction, created large gaps in the ground etc.
It ruined houses and farm land and made rivers flow the other ways, it also ruined precious buildings that have been very historic and some have been there for over 100 years.
Hope this helps
Originally, it was proposed that there was little reason to believe that natural processes caused the Newcastle earthquake. Investigations following the earthquake suggested that it was triggered by 200 years of underground coal mining. Geoscientists from Columbia University claimed that removal of 500 mega tonnes of coal and 2000 mega tonnes of water removed from the ground reactivated a major faultline underneath the Newcastle's coalfields. Removal of millions of tonnes of coal, and the pumping out of water needed in the mining process, created enough stress to reactivate a fault line beneath the Newcastle coal fields.
However, a 2007 report cast doubts on this theory, which came from a US report. Australian geoscientists believe more factors were involved, as evidenced by the fact that minor earthquakes have occurred in the Hunter Valley coal mining region from time to time, and not necessarily close to the coal mining sites. The epicentre of the quake was simply too far underground to have been caused by coal mining alone.

No. There were no warning signals prior to the Newcastle earthquakes.

Tsunamis are usually caused by an earthquake in the sea, and the earthquake may be caused by a volcano. An earthquake is also a natural disaster, because we did not create earthquake, it comes naturally.
Because they are caused naturally by plate tectonics and can have disastrous results

Tectonic plates caused the earthquake, the Pacific and North American plate were rubbing against each other, and this caused the earthquake. the earthquake caused the Tsunami.
a tsunami
It was caused by natural Earth processes. The movement of the Indian sub continent into the Asian continent driven by mantle convection.

Caused by natural forces!
No it is not. It is caused by man made CFC's.
yes its true!
an earthquake
No. There is no way they could have. It was a natural phenomenon.
the convection and conversion on plate boundaries, the diversion of plates as well
earthquake
The earthquake that struck Newcastle, Australia on 28 December 1989 caused significant damage throughout the city. 35,000 homes, 147 schools and 3,000 other structures in the region collapsed. The most damage happened at the Newcastle Workers Club when walls and multiple floors collapsed, dropping 300 tonnes of concrete onto the ground-floor car park, killing 9 people.
The Tsunami was caused by the large earthquake that preceded it.
