Coastal Problems

 To begin to get you to know what coastal problems are in Australia, it is coastal erosion. What is Coastal Erosion? It is when the ocean takes away things, for example, the waves hit the shore and take away a certain amount of sand or a rock, making the beach smaller or emptier. It is usually driven by waves and currents; however, coastal erosion is often associated with bad weather.


Many beaches in Australia are vulnerable to coastal erosion. There is an event called "La Niña". They call it this because it is the weather pattern that affects Australia. This typically happens in the spring and summer months. They had done a study of four decades with satellite imagery.  Dr Javier Leon is a lecturer in physical geography at the University of the Sunshine Coast. HE has estimated that in the past 3 years, the shoreline has retreated by 20 meters and sand dunes receded between 7cm and 10cm.


Australia is developing and understanding Coastal erosion. They developed methods and tools that can help support the coastal risk assessments, and they also support national initiatives to manage the coastal environment. Overall, they contribute the programs that will help them prevent, if not give notice to the residents.

    Hi Adrian,
    Thanks for sharing this informative post! Coastal erosion is definitely a serious issue, especially in a country like Australia with so many popular beaches. I didn’t know that La Niña had such a strong impact on shoreline retreat. It’s great to hear that researchers and national programs are working on solutions and tools to monitor the risks.

    Hello Adrian,
    It is surprising to read that the shoreline of Australia has changed 20 meters in just 3 years. It is good to see that Australia is using tools to help with monitoring coastal erosion.

    Hello Adrian,
    I enjoyed reading your discussion and learning about the impact tit has had from the event of La Niña. Similar to my country Chile where other weather events have impacted our coastlines where erosion has increased. It is important to be able to do more studies about erosion to be prepared for any sudden movement and destructions. Great post thank you for sharing!

    Hi Adrian, It’s good to know that Australia is not only aware of the issue but also actively developing tools and strategies to assess and manage the risks. I wonder what kinds of warning systems or policies are already in place to protect residents and coastal ecosystems. Coastal erosion seems like a slow-moving threat, but it clearly has real consequences for communities and the environment.

    Coastal erosion in Australia is a major issue, especially during La Niña weather patterns, which bring stronger waves and storms. It causes beaches to shrink as sand and rocks are pulled away by ocean currents. Studies show some shorelines have retreated up to 20 meters in just three years. To address this, Australia is using satellite data and new tools to assess coastal risks. These efforts aim to protect the coastline and keep communities informed and safe.

    Hi Adrian,
    It seems like coastal erosion is a big problem in Australia, I would expect it does because it is surrounded by water, i wonder how they have adapted over time to contain or solve these problems

    Interesting report! The Dominican Republic also has coastal erosion that affects the country. It can be a big problem for areas. Nice job!

Earthquakes

 Earthquakes do not occur as often in Australia. They don't experience earthquakes as much because they sit in the middle of the Indo-Australian tectonic plate. they are away from the boundaries and other tectonic plates where major and more frequent earthquakes occur. There have been a few that have happened frequently in 2021 Victoria got an earthquake that was 5.8 and 4.3 and western Australia was hit with a 5.3 that same year. the year after, another one had a magnitude of 4.8 in western Australia, and in March they had one in the south. Although they don't experience many earthquakes Adam Pascale is the chief scientist at Seismology Research Centre. He stated although there have been more earthquakes than usual, it is fine because they are happening in normal return time.  Below average Normal range Above average Although we don't get earthquake activity as much; the Indo-Pacific region experiences more disasters. However, Australia is working along their side to imp...

Extreme Weather Events

 Many extreme weather events are going on in Australia. Queensland is in the middle of a severe flood, there is a tropical cyclone going on in the Western part of Australia, and a lot of bush wildfires going on that were caused by storms and the hot and windy weather. However, we will be talking about the heat waves they have experienced.  In 2022 the Western part of Australia has gone through many heat waves. A town called Onslow In January they experienced a temperature of 50.7C and the conversion to Fahrenheit it will be 123 degrees Fahrenheit; another town called Perth had six days of 40 C temperature. The average temperature in Australia is 20-37 C. In 2015-2016 summer Perth had a record of 7 summer days that exceeded 40C. However, in 2021-2022 the city Perth surpassed that. Due to the major heat waves they experience they also experience the Winds and dry weather from the desert. Heatwaves are one of the major natural hazards that they experience in Australia. The reason...
