Volcanic activity

Image
  There aren't any active volcanoes in Australia. Volcanoes occur closer to the tectonic plate boundaries. The reason why Australia rarely has any volcanic activity is because there are no plate boundaries. However, this doesn't mean they do not have active volcanoes near them. The Heard and McDonald Islands are volcanoes that are on Australian territories. They are located on the southern ocean. Although they are active and not on the mainland it still causes damage to Southern Australia. This can cause blizzards, strong winds, and temperatures that can be dangerous. Since Australia very rarely has any volcanic activity they work on reducing risk to the community. They help by coordinating with the Department of Foreign Affairs and Trade and the Department of Defence offering to support them during any volcano eruption. https://whc.unesco.org/en/list/577/#:~:text=Big%20Ben%20on%20Heard%20Island,significantly%20in%20size%20since%20inscription . https://www.ga.gov.au/education/n...

Earthquakes

Image
 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...

Indo-Australian Plate

Image
 Tectonic To better understand what is going on in this picture. Convergent means where two plates are moving towards each other and colliding. Divergent   is when two plates are moving from each other Transform is when one plate passes by another tectonic plate. In less confusing words, they slide by each other but do not collide. Australia's Tectonic plate is the Indo-Australian plate, one of the 7 major Tectonic plates. Australia is the 6th largest tectonic plate. it is 8,900,000 square kilometers (22,700,000 square miles). The Australian Plate is combined with the Indian Plate however they are viewed as two separate tectonic plates. The Tectonic plate stretches to India and also goes into the oceanic crust of the Indian Ocean. As you can see in the image the Eurasian plate is outlined and this is because the Indo-Australian plate collides with it and this rises the Himalayan Mountain. If you take a look back at the first image you can see earthquake activity alon...
