  Week 5: Volcanoes  Australia is quite unique when it comes to volcanoes.  Australia counts 150 volcanoes mostly none of them have erupted in 4,000 to 5,000 years. Australia's inactive volcanoes are due to the island's location concerning a tectonic plate. One of the largest volcanoes found in Australia is located in Heard There are only two active volcanoes in Australia. These volcanoes are located 4,000 kilometers southwest of Perth in the Australian Antarctic. Geoscience in Australia uses expertise to help those who are affected by volcanic eruptions. They start monitoring the volcano and eruption forecast. The objective is to make sure they analyze the impact of a hazardous volcano.  Sources:  https://lisbdnet.com/how-many-volcanoes-in-australia/ https://www.ga.gov.au/scientific-topics/community-safety/volcano https://www.bbc.com/news/world-australia-60027360

 Week 3: Earthquakes   Australia is not commonly known for earthquakes but, they do occur. Earthquakes are most common in the Eastern Highlands of Australia. Earthquakes occur along with the pacific plates where the Indo-Australian plates crash among each other. The largest earthquake in Australia happened in 1988 with a magnitude of 6.6. Earthquakes are caused by how rapidly the Australian Plate moves. Earthquakes are a form of vibration caused by those rocks that become shattered with stress and pressure. It is essential to monitor and analyze every time an earthquake happens. Those who study earthquakes use seismometers to help them detect earthquakes. When collecting data, we look for the size and location of the earthquake. The study of earthquakes can reduce the chances of a claustrophobic event. Around 100 earthquakes of magnitude 3. are recorded each year in Australia.  Sources:  https://www.usgs.gov/search?keywords=Australia+earthquakes+ https://www.ga.gov.a...

  Australia northeast is a generally convergent boundary. The Australian Plate is a major tectonic plate. The Australian tectonic plate includes Tasmania, New Guinea, New Zealand, and the Indian Ocean. The Indo-Australian plate fused with the Indian Plate underneath the Indian ocean. Australia doesn't experience many earthquakes as it has no major fault lines. Large magnitude earthquakes usually happen once a year. The force build-up of pressure within the plate usually causes earthquakes.  Australia may be the world's most troublesome continent. Over time the county of Australia occasionally moves. Since the year 1994, the country of Australia has moved 4.9 feet northward. Australia is constantly moving because of the shifting of tectonic plates. Australia is one of the fastest-moving pieces of land.
