Week 16: Final Hazard Report The most dangerous natural hazard in Australia is a heatwave. More people pass away from heatwaves than any other thing. Addressing heat waves is significant as the destruction is immense. Heatwaves can lead to water shortage, ruin crops and increase health risks. Heatwaves can cause extreme effects on earth. The country of Australia must take action and mitigate the effects of the heatwave. The government should make green roofs more accessible to its citizens. Designing buildings with cool roofs that reflect sunlight away from structures. The government should give funds so the city can plant trees. The city should make shaded areas accessible so people can cool off. The first place I would offer help in Melbourne and Adelaide. I would target those areas where heatwaves are long-lasting in southern Australia. I would also take into consideration desserts where heatwaves are common. I would make sure help would reach out to all subur...

Week 13: Coastal Hazards Anyone who lives along the coast should consider the risks of flooding, rising sea levels, and erosion. Australia's coast is at risk due to a rise in sea levels is a threat we will constantly face. Australia is the country most affected by beach erosion. Australia has around 11,426 kilometers of coastline that face risk. More than 40% of beaches are at risk of being lost. Coastal environments have been affected by pressure such as extreme weather and human development. Coastal floods will increasingly occur due to smaller storm surges and ties alone under average oceanographic conditions. Cities like Sydney, Melbourne, and Perth have been affected by flooding. People must be aware of the government meteorological organizations and stay tuned to warning protocols. Australian citizens should carefully consider insurance that covers weather hazards that include flooding. NGIS has developed a tool to help people visualize how their homes and neighb...
Week 10: Extreme Weather Australia experiences different forms of severe weather depending on its regional area. Australia's extreme weather usually occurs from October through April as droughts and thunderstorms are seasonal. The wettest regions are around the west coast of Tasmania. The effects of a wide varied rainfall pattern and Australia's drainage system can cause parts to begin to drought. The warming over the upper northern part of Australia creates low pressure and rising air. As a result, it brings moisture from nearby oceans. The northern ocean of Australia particularly around Indonesia is warmer. It can lead to moisture-rich air flowing toward Australia. It increases the chances of having heavier rainfall. Phenomena weather can cause significant damage to homes and communities. It's critical to take safety precautions during any natural hazard. It's always beneficial to act in advance before a disaster occurs. There should be plenty of safety measures pla...
Landslides are due to heavy rain saturating soil on a hillside. Landslides occur when vegetation can no longer support the soil’s weight against the force of gravity. Compared to other countries, Australia experiences minimal landslide activity. Australia usually receives minimal rainfall. Areas that experience landslides include cliffs along the ocean that receive large amounts of showers. Australia takes certain precautions to minimize the effects of landslides and increase the chances of survival. The Australian government looks at past tragic events that help them impose stringent planning. When building new structures they look for areas with a low risk of slope instability. They map out those areas that are vulnerable to landslides. Taking the correct measurement of precaution can protect us from any vital damage.

Week 5: Volcanoes
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.

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.
