Two Earthquakes In Australia
Earthquakes in Australia
Australia is a very lucky country that suffers very few earthquakes or volcanic eruptions. Earthquakes are caused by converging plates (usually subducting), and there a 4 different types of waves in two categories; firstly there is Body waves which are broken into primary and secondary waves (these travel through the earth) Surface waves travel through only the crust and are called Love and Rayleigh. These Waves (the earthquakes) are measured by a seismograph/ a device that monitors the Earth’s vibrations. There are hardly any earthquakes in Australia and only even a minority of them have caused major damage. Within this century there has only been 1 or 2 earthquakes which caused a great amount of damage and deaths …show more content…
As shown in this map Australia encounters many earthquakes (most under magnitude5) and the majority of them occur around the South-eastern coast. Other quakes occur in the ocean which explains why the waves from South Australia to Western Australia can be so good at certain times of the year. The way the earth is evolving today may lead to big changes within 100 years and who knows till then Australia could be in the middle of a tectonic plate boundary and there may be many destructive earthquakes within 100 …show more content…
It is in the middle of the Indo-Australian plate which makes it difficult for a quake to be created. As you can see from earthquakes in Australia over a 4-5 year period we became more conscience of saving lives of our citizens. in 2010-11 that was when one more earthquake or tremor occurred which shook the nation and as a result disaster response rose. When you compare disaster response to the other categories on the chart we realise the earthquakes are very un common and that if they do strike it is usually with very little force. Earthquakes can happen anywhere but mostly occur on plate boundaries that are converging and subducting tectonic plates. It would be an outburst to say that no dangerous earthquakes occur in Australia, or none at all as recently stated by the one in Newcastle.
By looking at statistics and evidence it is shown that the world will evolve and change, it is in constant movement. Australia may end up in the ring of fire (one of the most dangerous areas of volcanic and ground activity). It is too hard to tell if Australia will encounter a major geological event such as a large earthquake, but anything is possible. Cities will expand into wider Australia and maybe those earthquakes that are powerful but don 't affect much will have a large impact on
